Do-it-yourself air conditioner pipe repair
In detail: do-it-yourself air conditioner pipe repair from a real master for the site my.housecope.com.
Repair of car air conditioning pipes can be carried out both because they are broken, and because they are dirty and cannot be cleaned. In winter, when the air conditioner is not running, aluminum hoses and pipes can become clogged, especially between the engine radiator and the air conditioner radiator. Contaminant particles can accumulate that can contaminate the lines. And all this in combination can interfere with the proper circulation of the refrigerant and mixing of refrigerant and moisture is simply inevitable.
The tubes themselves are made of aluminum, so external factors can destroy this material. Temperature fluctuations, violation of the level of moisture, the presence of reagents - all this can lead to the destruction of aluminum. And besides this, there are sealing rings and rubber gaskets, which, under the influence of various factors, can collapse even faster.
The performance of aluminum tubes is affected by the climate of the country, temperature, road surface or lack of it, the overall load on the car and getting into traffic accidents.
All this negatively affects the operation of the cooling unit, and as a result, the repair of auto-conditioner tubes is simply inevitable.
You may mistakenly think that nothing depends on the performance of the tubes, but its durability will depend on how timely the repair of the tubes of the auto-conditioner is carried out. Tightening can cause the compressor to depressurize and you will have to perform a complete replacement of the device. Worst of all, if during the wear process the car owner does not notice this and the climate system becomes contaminated with particles of compression rings. In this case, not only the entire system is endangered, but the health of the passengers of the car will be impaired. Many have already felt for themselves that there can be real health problems from the cooling system.

Repairing air conditioning pipes is easy if the cracks are very small, which are barely visible to the eye. In this case, you can not use argon-arc welding, but use special compositions. The so-called soldering of holes in the form of patches is performed. Such mixtures can be applied in several layers so that their thickness is 2-3 millimeters. Thus, we achieve high-quality repair of the air conditioner of the car.
Welding of air conditioner tubes will be needed if the dimensions of the cracks exceed the norm of 2-3 millimeters. In this case, we acquire argon-arc welding and go to work.
Soldering a car air conditioner pipe

If you want to save a lot on repairing air conditioning pipes, you will have to do it yourself. I want to note that this will still require soldering experience, albeit a small one. It is important to stock up on a specific tool: a pipe cutter, a special bending machine and welding. Please note that a pipe cutter can also be replaced with a metal file, but this will not be the quality that we expect in the repair of auto air conditioning pipes.
The pipe bender can be both universal (for different diameters) and specific (for a certain diameter). When choosing this tool, it is worth knowing what sizes are used in your machine. Often this is a 6, 8, 10 size, which corresponds to the inner diameter in millimeters. You can look at the size on the car system or in the technical documentation.This is a fundamentally important repair issue, since different machines use different measurement systems.
Repair of auto air conditioning pipes begins with the fact that you need to buy or make parts. Next, cut off the required length and bend them with a bending machine. When the tubes are ready, we cut the fittings and connect it all into a single system. Before soldering, it is worth rewinding the parts with electrical tape and see if you did everything right. If everything fits, then we start soldering.
When repairing car air conditioning pipes, it is not always possible to resort to the above method. Sometimes the air conditioner tubes are replaced with hoses that are made of rubber. Although they are made of a less resistant material, replacing them will be very quick, simple and cheap. Welding of air conditioner tubes is not used here, usually the hoses are screwed in.
Welding of air conditioner tubes is also used if they are made of copper. The copper type of connections is more resistant than aluminum, but it is expensive. In this case, it is necessary to perform flaring. And this is a job for professionals with a high-quality specific tool (it is present only at good service stations). Sometimes insulation is performed for such parts, which saves from freezing in winter and performs thermal insulation of the system.
At the end of the article, I would like to note that you need to monitor the cooling system very closely: listen to the sounds in the operation of devices, to smells and to general performance characteristics. All this can tell you in time about problems that are easy to fix in the early stages. Take care of your car and it will serve you for many years!
On the recording, an auto expert shows how to properly solder the copper pipe of an automobile air conditioner.
Repairing car air conditioning pipes is a common problem that every driver has to deal with at some point. Minor damage to the tube leads to the fact that freon begins to leave the system, due to which, in turn, the air conditioner ceases to function. Armed with knowledge, the necessary tools and finding some free time for all this, you can fix the pipes and pipes of the air conditioner with your own hands.
Tubes can be repaired not only due to mechanical damage, but also in case of severe contamination, when the product cannot be cleaned. In winter, for example, when the air conditioner is not in use, all aluminum connections can become clogged. Often, the area between the radiators of the air conditioner and the car engine suffers from clogging.
Note!During the operation of the vehicle, the lines can become contaminated due to the accumulation of small particles. This leads to a violation of the circulation of the refrigerant in the air conditioning system, as a result of which moisture begins to mix with the coolant.
Air conditioner tubes are mainly produced from aluminum - it is a light, reliable and relatively inexpensive material. But various external factors can adversely affect the product. Exposure to reagents, increased humidity or sudden changes in temperature - all of these factors, together or individually, contribute to the destruction of aluminum. In addition, the design of the system contains rubber gaskets and rings, which, when exposed to all the same factors, are destroyed much faster than tubes.
Dirty air conditioning pipes
There are other causal factors that reduce the performance of the aluminum tubes of the car's air conditioner. The most common of these include:
participation in an accident;
driving style;
total load on the system;
the quality of the road surface;
the impact of the temperature regime;
the climate of the region where the car is operated.
Rust on air conditioning pipes
All these factors negatively affect the performance of the air conditioner and all its components, so the tubes of the cooling unit sooner or later have to be repaired or replaced.
With a small refrigerant leak from the system, it is quite difficult to recognize damage to the pipes in the early stages, since the system will then function normally. But at the same time, the system will require more energy and time to cool the interior of the car. Also at this stage, when the air conditioner is on, fuel consumption will be slightly increased, which cannot be overlooked when operating the car.
Diagnostics of the car air conditioner
If there is practically no gas left in the system, but this is enough for the system to work, then the air conditioner will work without any signs of malfunction. Cooled air will flow from the air ducts into the passenger compartment, but the car will no longer be able to be cooled. With a complete leak of freon, various symptoms may occur. Many modern models are equipped with systems that alert the driver of a possible problem. Also, these systems turn off the air conditioner on their own to avoid serious damage to it.
On a note!If there is a complete leakage of coolant from the system, it is necessary to turn off the air conditioning compressor. This is necessary if you plan to continue to operate the vehicle with the air conditioner not working. Otherwise, the included compressor can lead to breakage of some components of the system.
Even though there are a large number of high-quality car services in every city in the country, many motorists prefer to fix minor problems on their car in garage conditions. Avid motorists spend all their free time repairing their swallows, because self-repair is not only money saved, but also a real hobby and new experience gained.
Depending on the severity of damage to the air conditioning tubes, different repair methods are used, for example, argon welding, special repair compounds and ready-made kits purchased from a specialized store. Let's consider each of these methods separately.
A common way to repair damaged air conditioning pipes, but its implementation requires a welding machine, which not every motorist has. It is necessary not only to have such a device, but also to be able to use it, so that repair work has at least some efficiency. The repair process is very simple: you need to remove the damaged tubes of the air conditioner and, having carried out their visual assessment, “patch” all the holes that have formed.
What does argon welding look like
If small cracks appear on the part, then they can be repaired with the help of special repair compounds. Most of these products are available in the form of an aerosol, so they are easy to use. It is enough to apply a small layer of repair agent to the damaged section of the tube and wait.
Air Conditioner Radiator Internal Repair Sealant
For complete solidification of the composition requires at least 10 hours. After this, the product must be installed back on the air conditioner, and the system itself can be fully operated.
For most car models in specialized stores, you can buy air conditioning pipes made of rubber or aluminum. The difference between them lies not only in the material used, but also in the complexity of the installation process and the price of the products. If you want to get the job done faster, but at the same time the repair budget is small, then rubber pipelines are worth choosing.
A/C pipe repair kit
Important!The operation of a car of early years of production implies frequent repair of pipelines (it is necessary to carry out repair work every 1-2 months).In such cases, it will be much easier and cheaper to replace the damaged air conditioning tube than to regularly waste your time trying to fix it.
Provided that the area of \u200b\u200bdamage to the pipelines of the air conditioning system is small, all repairs can be successfully carried out on their own, without having experience. Also, repairs are carried out without outside help, the main thing is the desire and some free time.
Repair of car air conditioning pipes
The cost of repairs in a car service depends on several factors, for example, on the model of the car and the difficulty of installing system elements, as well as on the region in which the repair will be made. It's no secret that in Moscow or St. Petersburg the prices for car repairs are much higher than, for example, in less populated cities. This must be taken into account if you still decide to entrust the repair to specialists.
Result of air conditioner repair
Provided that all actions are performed correctly, the performance of the car's air conditioning system will be fully restored, and you will again be able to drive on hot city streets in conditions of increased comfort.
During the operation of the air conditioner, various troubles occur. The most common problem is tube repair.
When using the air conditioner in cooling mode, when the outside temperature is below zero, an ice plug may form in the drain pipe, blocking the condensate drain hole. The main consequence of this circumstance will be a leak from the indoor unit. In this case, no repair is required. You just need to wait until it gets warmer outside, and the cork will melt itself.
More serious difficulties are caused by damage to the pipes for the refrigerant of the air conditioner, arising from the following reasons:
violation of the integrity of the surface of the tubes due to mechanical damage;
rubbing of the inner tubes due to strong vibration during increased operation of the compressor or fan;
deformation or destruction of the walls of the tubes under the influence of the environment (UV radiation, wind, precipitation and other factors).
The split system is designed so that the most vulnerable area is the highway connecting its main modules. As soon as a refrigerant leak is suspected, the first step is to visually inspect the freon route. Usually it consists of tubes that should not react with freon and oil. In this case, it is necessary that they be protected from corrosion.
Copper is the best suited for such purposes. When interacting with chlorine contained in freon, copper is oxidized and covered with a protective layer that prevents rust.
It works through the use of human muscle strength, has several types of semicircular nozzles.
There is not always a special tool at hand, so in order to bend the tube, you can use another method. For example, using a spring.
First you need to choose a spring. If the tube diameter is large, then a smaller diameter spring is used, which is pushed into the tube. For a thin tube, you can take a large spring and put it on top.
2. Then heat the tube with a gas burner or blowtorch.
3. When the metal darkens, you can start bending.
4. Leave the workpiece to cool completely.
The aluminum tube is also widely used in the installation of air conditioners and for the supply of refrigerant, as it has several advantages over copper:
low price;
better flexibility;
speed and ease of soldering, saving effort and time, as well as the consumption of solders and gas;
low thermal conductivity;
higher corrosion resistance;
softness allows you to spend less effort on flaring.
The properties of aluminum are such that its surface is rapidly oxidized under the influence of oxygen and a protective oxide film appears on it.This film interferes with the soldering of aluminum tubes.
Therefore, the question often arises: how to solder the aluminum tube of the air conditioner? If such a need arose, it is recommended to use fluxes and solders. With them, the seams are smooth and durable.
For soldering aluminum parts you will need:
gas balloon;
solder for soldering aluminum (for example, Castolin 192 FBK);
gas burner or blowtorch.
back to index ↑
Surface cleaning from oxide film and contaminants. This is done in two ways: mechanical (using a grinder, sandpaper, metal mesh or brush) or chemical (using chemicals - fluxes).
Putting parts in the right position relative to each other.
Applying flux to the joint.
Heating a tube with solder with a blowtorch or gas burner.
Solder application. At the same time, overheating should be avoided, as a result of which the parts to be joined can melt. It is necessary to control the process of heating to the operating temperature by constantly applying solder. When its tip begins to melt, then the temperature is optimal.
If the flux is not used, then the tip of the solder should be made with a striking movement. This measure will help get rid of the oxide film and make the seam more durable.
Soldering helps to solve the problems of repairing worn parts, leaking tubes, without resorting to the expensive help of qualified specialists.
Automobile air conditioning is one of the most significant and significant achievements of modern automotive industry. The ability to cool the air inside the machine is worth a lot. The use of an air conditioner is especially important for countries with a hot climate, where high ambient temperatures persist throughout the year.
Heat has a depressing effect on the human body and with age, negative factors tend to intensify. The presence of an air conditioner in the car allows you to adjust the air temperature to optimal values. The air conditioner, like any air cooling unit, has its own system for distributing cooled air masses throughout the vehicle interior.
The elements of the freon gas transport system, which is used to lower the air temperature, are pipelines running in the engine compartment. For the manufacture of pipelines used aluminum. This is a rather "capricious" material with low resistance to temperature extremes and external factors. During long-term operation of the vehicle, it may become unusable in some areas.
Damage to the air conditioner pipelines leads to freon leakage. It is a gas that cools the air circulating through the car's ventilation system. Freon leakage can lead to failure of the vehicle's air conditioning system. That is why it is very important to know how to repair the air conditioner pipe with your own hands.
The pipeline of the vehicle air conditioning system is located in the engine compartment of the vehicle. In modern cars, it is impossible to stick even a finger under the hood. All working elements of the engine and other systems are located very tightly. Not surprisingly, when repairing a car, there is a risk of damage to the air conditioning pipes.
Often the active operation of the vehicle leads to wear of the elements of the air conditioning system. Despite the fact that the tube is made of aluminum, it is quite easily damaged by careless handling by car service specialists or external factors (temperature changes, corrosion, friction and vibration).
Freon begins to leave through cracks in the pipelines of the air conditioning system. It is a volatile gas that evaporates quickly. Visually or by smell, it is not possible to determine the leakage of freon.
The peculiarities of the country's climate suggest seasonal operation of the air conditioner.Active use of air cooling occurs only 4 or 5 months a year. The rest of the time the air conditioning system is inactive. During the idle period of the air conditioner, the system piping becomes contaminated with dust or dirt. All this negatively affects the efficiency of the system in the future.
Despite the emergence of a sufficient number of car service stations, garage repairs are popular among the majority of drivers. Some car enthusiasts spend the whole weekend on fixing their "iron horse". This is a real national hobby that combines excitement and a real opportunity to save money.
In most vehicles, one press of a button is enough to activate the air conditioner and cool the air. If warm air flows from the ventilation system, then the air conditioning compressor is not working. You need to look for the cause of the malfunction.
If you have any concerns regarding the performance of the air conditioning system, do not hesitate. Early diagnosis makes it possible to quickly identify malfunctions and take measures to eliminate them.
Connecting special equipment for diagnosing the air conditioning system of the machine allows you to determine the location of the freon leak. It is very convenient and saves a lot of free time for the motorist.
Detecting a refrigerant gas leak allows the vehicle owner to take other steps to repair the air conditioning system.
Small cracks on the surface of air conditioning pipes are easier and faster to repair using special repair compounds. As a rule, they are sold in aerosol form and applied to the site of damage through spraying. It does not take much time to harden the working substance of the repair composition. After 12 hours, the air conditioner can already be used.
The presence of a welding machine, despite its availability, is not common. The device must be able to use it correctly, otherwise the repair efficiency will tend to zero. If the pipelines of the air conditioning system resemble a sieve, it is best and more profitable to use welding.
If the car is of early years of production, it is often necessary to repair pipelines. Often a month does not pass without repair work. In this case, it is easier to replace the air conditioning piping than to try to “pat it up”. It will be cheaper and more efficient.
For almost all vehicle models, aluminum or rubber air conditioning piping is available. The difference lies in the cost and complexity of the installation. Rubber piping is more affordable and easier to install.
The choice of means for repairing the pipeline of the air conditioning system is wide and varied. That is why it is difficult to make the right choice and acquire an effective remedy. Savings will have a negative impact on the repair effect, as it will be short-lived.
We can distinguish the following popular means among motorists for repairing car air conditioner tubes:
1. Mannol Epoxidkitt Stahl + Metall.
Special repair compound for restoring the surface of air conditioning tubes. Convenient for quick do-it-yourself repairs. All damage is effectively filled. Suitable for repairing metal elements. Complete hardening of the composition occurs after 15-20 minutes, depending on the ambient temperature.
2.MANNOL EPOXY-METAL (30 gr.).
Special repair composition on epoxy resin. Provides fast bonding of damage on the surface of air conditioning piping. Complete curing of the product occurs after 5 minutes.
3. Self-sealing rubber tape Mannol MULTI-TAPE 5M.
Insulates and protects the elements of the pipeline of the air conditioner from corrosion.The tape is resistant to mechanical stress, temperature extremes and aggressive environments. Easy-to-use and effective tool for repairing the air conditioning system.
If desired, and a small area of \u200b\u200bdamage to the air conditioner pipelines, all repair work can be done independently without outside help. Actions will help restore the efficiency of the vehicle interior cooling system.

Car air conditioning tube repair is an inevitable problem that every motorist faces sooner or later. If the tube is cracked or defective, freon will leave the system, which will lead to the failure of the car's air conditioner. Armed with the necessary tools, materials, patience and time, repairs can be done independently.
Many car models are designed so that the pipeline leading to the air conditioning compressor runs next to the exhaust manifold. Due to the constantly high temperature, gradual burnout, cracking and drying of these elements occurs.
The winter period is characterized by blockages in pipes and hoses, as a result of which the space between the radiator that cools the engine and the car's air conditioning system is filled with dirt. In addition, aluminum tubes are significantly affected by factors such as exposure to road chemicals, temperature changes, increase and decrease in humidity.
When repairing a car air conditioner, in many cases argon-arc welding is necessary, especially when it comes to large cracks. However, minor damage can be dealt with without the use of a welding machine. In this situation, special compositions are used that are sprayed onto the surface in several layers. Thus, a kind of patch is obtained. It will only take you a few minutes to make.
After applying the funds, it is necessary to put on a rubber tube of a larger diameter, which would completely cover the repaired part.
In many cases, making new car air conditioning parts will cost significantly less than buying them. If you decide to take this step, it is very important to correctly measure the necessary parts and have the right tools. In order for the manufacture to go smoothly, you must have a high-quality pipe cutter, pipe bender and several other tools in your arsenal. The pipe cutter will allow you to achieve high-quality trimming of the edges of the tube, and the pipe bender will make it possible to bend it at different angles without the risk of breakage.
An equally important point is the choice of tubes directly. Be careful - the manufacture of parts should be carried out in the measuring system that is indicated in the vehicle's data sheet. Drivers often confuse inches with meters. To select suitable elements, it is necessary to measure the part on the fittings of the system, cut and, if necessary, bend in the right places, and also connect by welding.
Some vehicles are equipped with air conditioning systems that cannot be repaired in the manner described above. Rescue hoses for car air conditioners made of rubber. This material, as you know, tends to crack and dry out, in addition, rubber, in comparison with metal, is much more susceptible to mechanical damage.
In case of slight damage to the rubber hose, it can also be patched with special tools and compounds. However, with large defects, the hoses for the car's air conditioners must be replaced with new ones, fortunately, their manufacture will cost you a small amount.
It is very important to carry out repairs related to the car's climate system on time, otherwise malfunctions can lead to depressurization of the air conditioning compressor. And this, in turn, will cause clogging of the car’s climate system with particles of compression rings, which can lead to more serious damage and financial repair costs.
The air conditioning system consists of many elements that can wear out over time and lose their primary functions. One of these is the tubes through which cold air and gas are transferred, which are necessary for the normal operation of the conder. In what cases is the repair of tubes of car air conditioners carried out and how to do this task with your own hands - find out from this article.
The need to repair the tubes of the car air conditioner may arise as a result of their breakdown or contamination. Moreover, the pollution can be so serious that the hoses themselves can no longer be cleaned. In the cold season, when the air conditioner practically does not turn on, the system lines can become clogged, especially pollution collects in the area between the radiator devices of the motor and the air conditioner. Accordingly, contamination of the tubes of the car's air conditioner can interfere with the optimal circulation of consumables, which will subsequently lead to mixing freon and moisture.
The mains of the air conditioning system are usually made of aluminum, respectively, various external factors can adversely affect this material. Due to temperature changes, violation of the moisture level, as well as the presence of various reagents, aluminum can simply collapse. In addition, the tubes of the system are also equipped with gaskets and seals, which, in turn, are also destroyed, only even stronger and faster. The service life of the tubes depends on many factors - the conditions for using the car, the climate of the region, temperature, the load on the car as a whole.
So, for what reasons tubes fail:
due to temperature changes;
as a result of exposure to road chemicals;
due to contamination;
due to changes in humidity;
as a result of severe frosts;
when a car is involved in an accident.
If air conditioning hoses are being repaired, then, as a rule, cracks can be patched using argon-arc welding. In particular, if the cracks are sufficiently large in size. As for smaller damages, you can get rid of them without a welding machine. To remove such damage, you can use special compounds that must be sprayed onto the surface of the tube in several layers. It is desirable that when welding air conditioner pipes, the total thickness of the patches is about 2-3 mm.
It should also be borne in mind that usually the process of producing new pipes for the Conder is much cheaper for the car owner than purchasing them. For manufacturing, it is important to correctly calculate all dimensions and prepare the necessary tool. So that the production process does not cause difficulties, it is necessary to prepare in advance a high-quality pipe cutter, as well as a pipe bender. The first one will allow you to cut the edges of the pipe with the highest quality, and the second one can be used if necessary to bend the pipe at an angle (the author of the video is Denis Chesnokov).
If you decide to repair hoses, then first of all you need to decide whether you will buy parts or make them yourself. During production, you need to be careful and correctly measure in accordance with the technical documentation for the machine. In practice, our compatriots quite often confuse meters with inches, as a result of which the repair procedure can be difficult.
A few things to keep in mind when renovating:
In any case, if you want the air conditioning system to work for a long time and without complaints, its condition should be monitored, especially during the off-season.You should always pay attention to the sounds that appear during the operation of the conder, as well as the smells that may come from the blowers. Of course, you also need to pay attention to the efficiency of the system - if you notice that the conder has become less efficient, this may indicate various malfunctions. Moreover, as practice shows, most often they are best eliminated at the initial stages.
The video below shows the process of repairing car air conditioning hoses (the author of the video is the Tim Service channel).
And so, today I learned from specialists that the repair of the tube costs about 15,000 rubles.
Armed with my knowledge, I made it with my own hands.
Everything will be in the photo. The repair is shown on landcruiser100 from 2005 to 2007 two zone (two climate control)
who knows and who doesn't - these years of production, illness, on the passenger side near the threshold. The high-pressure tube rots (thin)
1)two couplings
2) a piece of aluminum tube (preferably in foam protection)
3) time two hours and accuracy.
We look at the photo. (In the last photo, these are the remains of the tubes, and two couplings are N.C.)
Great idea. I am from Yekaterinburg, we have a problem with an aluminum tube for condos, a copper shaft. I found aluminum tubes in Leroy Merlin for 90 rubles per 2 meters, but they are tough to bend. There are also softer tubes on the bases. The question is, what brand did you use, the diameter and wall thickness of the tube. The connecting nipples are commercially available from gas workers, but they are 8=8, 10=10, and I didn’t find them to use the transition from a smaller to a larger one. What materials did you use. I have a 2000 Kruzak car. The tubes stood for 15 years = there were no problems.
I bought nipples (compression sleeves) 8mm = 8mm Lovato for 350 rubles, a heater tube 6 * 12 foamed rubber from air conditioners for 17 rubles / meter. By the way, it is put on a tube with a diameter of up to 9.25 mm. the aluminum tube bends after heating with a thermal gun to 400 degrees without creases, I put on a spring for insurance from the outside to exclude cracks and creases. After bending, I just took it off. Cooled in the air. I'm going to install everything next week. By the way, the couplings can withstand pressure up to 23 atmospheres. Practice will show what will come of all this. While the costs are ridiculous 2 tubes of 90 rubles each, two couplings of 350 each and a heater 4 meters of 17 rubles each Total 948 rubles. I bought everything in reserve. Let lies you never know what will go wrong in the service.
I found an aluminum pipe Brand AMG2M 8 * 1 OST 1.92096-83 1 meter costs 68.75 rubles. In the garage they suggested looking for couplings for connecting pipes 8 = 8, in a store for Kamaz, they have pneumatic pipes 8 and 10 mm. I'll check out the prices. Tomorrow I'm going to collect the designer.
I went to the service, a technological sink, replaced the tubes, added 1 liter of antifreeze, refueled the air conditioner. Total: 2500 rubles. Special thanks to xekxek
Hello, I really liked your method of repairing pipes, but where to buy couplings?
I bought from people who install HBO on cars, they have a large assortment, there are steel, there is bronze, I chose the second option = does not corrode)))
The connection of the nodes of any air conditioner is carried out by tubes and high pressure hoses.
Any destruction of the pipeline causes freon leakage and breakage of the "heart" of the air conditioner - the compressor.
Repairing the high pressure pipe of an air conditioner is not a difficult process, but it can only be done with special equipment.
Welding of cracks and open seams is possible only in an argon environment and is carried out by argon-arc welding.
Diagnostics is carried out when the air conditioner fails.
It is practically impossible to independently determine the condition of the pipeline. Freon leakage can occur through microcracks formed in high-pressure pipes or hoses. They are not noticeable to the eye, and freon is colorless. You will not see it without special detection devices.Specialized service stations have equipment that allows you to accurately determine the location of a refrigerant leak.
Sequence
diagnostics:
visual inspection;
measurement of freon pressure in the system;
determination of the place of destruction of the tube by a leak detector;
ultraviolet diagnostics.
As you can see, the diagnostic process requires special equipment. There is no way to independently detect the place of freon leakage from a tube or hose. Such equipment for pipeline diagnostics is available at our service.
Repairing aluminum air conditioning tubes on a car is a problem that every motorist has to face. Some try to make it on their own. True, in most cases they still have to seek help from the service station and correct what was done with their own hands. The process of restoring aluminum tubes is carried out in two ways - by welding cracks and by spraying several layers of a special composite onto microcracks.
In argon-arc welding, all
the welded surface of the tube section is in an inert gas environment - argon. It is not possible to weld aluminum without it. The work is performed by a special welding machine designed for welding non-ferrous metals.
If the crack is small, barely noticeable to the eye, it is sealed. A special composite is applied in layers to the crack. When the total thickness of the layer reaches 3 mm, the work is considered completed.
Depending on the damage during the diagnosis, a decision is made on how to eliminate it. A situation may arise when replacement becomes more expedient and cheaper for the client than welding or soldering auto air conditioning pipes.
Defective rubber hoses must be replaced. On the Internet, you can find tips from “craftsmen” on how to repair a hose with your own hands, but you should not do this, since rubber is rubber. After a week or two, its gap will come out again, since the internal pressure of freon in the system is quite significant.
The pipeline of the conditioner has rigid fastening. It would seem that tubes and hoses (for example, an aluminum tube for car air conditioners) should last forever. Unfortunately, this is far from the case. There are several reasons here:
piping next to the outlet the collector cracks and burns out over time;
pollution and temperature fluctuations;
influence of road reagents;
significant fluctuations in humidity;
constant vibration from a running engine.
These and other factors have a devastating effect on aluminum tubes and rubber hoses. Therefore, sooner or later there comes a moment when they cannot withstand the load and become unusable.
Pipeline Maintenance
car air conditioning will not cause difficulties even for a novice motorist.
Keeping clean, periodic inspection - that's all you need to do to extend the life of pipes and hoses for several years. The only thing that must be strictly observed is the use of neutral materials for maintenance. To do this, water, a wooden scraper and a hair brush are suitable. The use of solvents and detergents is not recommended.
At our service, you can carry out high-quality repairs of tubes and high-pressure hoses of air conditioners of any brand. The service is equipped with the most modern equipment, including the restoration of pipelines. Highly qualified welders and mechanics perform work quickly and with high quality. Numerous thanks and positive reviews confirm this.
