Crack repair by cold welding
Modern household communications are increasingly equipped with plastic pipes: this is especially true of sewer and plumbing systems, most of them consisting of polypropylene or PVC products. Like any other plumbing, these systems need periodic repairs.
First steps to take if a leak is detected
If on a heating pipe or high pressure there is a leak, it is necessary to immediately block the system with shut-off valves. To solve the problem, how to close a hole in plastic pipe, you can apply a clamp. Such designs are characterized by a very simple use, which consists in putting on a damaged area and tightening the bolts.
More old way is to use rubber: in this way heating and water pipes. This involves wrapping a piece of rubber around the damaged area, for which you can use an old car tire.
Clamp is used for clamping thin wire or strong cord. It also applies to the usual Oil paint, which is smeared on a fabric pre-wound over a leak (read also: "How to fix a leak in a plastic pipe - options for sealing a leak"). All these methods have only a temporary effect, since the leak will definitely make itself felt later. The best option how to close a crack in a plastic pipe is to completely replace the problem area, especially since in the case of plastic pipes this is not difficult to do.
Use of sealant and epoxy glue for plastic pipe
The appearance of cracks or leaks in the plastic pipeline can contribute to whole line factors. These are mistakes made at the stage of system installation, and violation of operation. Yes, and yourself plastic parts may be defective.
If the size of the resulting crack is small, then it is not necessary to change the entire pipe. You could try sealing it first. silicone sealant, especially if we are talking about non-penetrating damage.
How to seal cracked plastic in the refrigerator?
Most often, sewer systems are repaired in this way.
In this case, you need to act like this:
- Clean up and expand the damage. This is done for deeper penetration of the sealant.
- Carry out degreasing and drying of the repaired area.
- Apply the desired layer of sealant and allow it to dry well.
However, it happens that the pipe receives through damage. How to seal the sewer plastic pipe in this case?
This is done using a two-component epoxy composition, in compliance with the following sequence of work:
- The place where the damage appeared must be cleaned, degreased and dried.
- To prepare the bandage, you will need fiberglass or another dense and flexible material.
- The crack itself and the place around it are wrapped with a prepared bandage, with a good margin. Wrap the material around the pipe at least 5 times.
- At the final stage, epoxy glue is applied.
Except sewer systems, thus it is possible to repair water pipes and heated towel rails.
How to seal a hole with duct tape
With this modern material it is possible to qualitatively eliminate small leaks on the pipes located in the bathrooms. Outwardly, it is an adhesive fabric impregnated with special substances. Most often, joints and connecting elements are sealed with sealing tape. As for straight sections, they can also be repaired in this way.
When using sealing tape, it is important to follow the following sequence of work:
- The damaged area must be thoroughly cleaned and dried.
- After stretching a small piece of tape, it is wrapped around the pipe. It is important that this procedure is accompanied by constant tension in the tape, otherwise wrinkles will occur.
- When winding, each new turn should be laid on half of the previous one. It is best to pack the pipe with two layers of sealing tape.
The main disadvantage of this method is the insufficient resistance of the repair material to sunlight. To achieve a good service life, the wound tape is coated with additional protection.
Crack repair by cold welding
At present, specialized stores offer special cold welding for sewer pipes. It is made specifically for repair. plastic products used in the organization of water pipes, cooling systems, heating communications.
With the help of cold welding, damage of almost any degree of complexity can be repaired. In this case, thermal exposure is not required, since a chemical reaction is used to bring the constituent components into working condition.
The work itself to repair a damaged plastic pipe has the following sequence:
- It all starts with surface preparation, for which the entire problem area is treated with an emery cloth. This is followed by degreasing the base with alcohol-containing liquids. If this procedure is neglected, the applied patch will serve many times less.
- It is necessary to calculate exactly how much material is required for high-quality embedding. For this, a simple visual inspection is usually enough: the main thing here is that the repair mass can cover the entire problem area.
- The substance must be taken into hands, which are previously put on protective rubber gloves, and start kneading. This procedure is continued until the material is stained in a specific brown shade. Another sign of the readiness of the material is the mass reaching the state of plasticine.
- The finished plastic material must be well repaired damage by pressing it with a tourniquet. Then a pause is made in the work, for about an hour: during this time, the repair mass solidifies. It must be made so strong and dense that any drilling, cutting and other influences on its surface are completely safe.
It is important to take into account the presence of components harmful to the human body in the composition of cold welding. For safety reasons, it is recommended to get protective gloves and goggles in advance. To speed up the process of solidification of the plastic mass, some experts recommend acting on it warm air using a building or regular hair dryer.
Cold welding for sewer pipes is suitable for repairing damaged plumbing. For example, if a piece of material has broken off from a sink or toilet bowl, cold welding will help glue it back with high quality. When buying this universal remedy, you should check its expiration date, composition features and the availability of a quality certificate.
How to solder a plastic container
Is it even possible to seal a container or gas tank made of plastic?
How to solder a plastic container? In our time, there are many invented methods for welding cracks, holes, burst seams, equipment for such repairs is also diverse from a soldering iron to a hair dryer, whoever is much better. It can be repaired with such tools, but where is the guarantee that it will not leak again. Such repairs will be just decorative and in the future the owner will incur new costs. It takes knowledge of the material and practice. Our craftsmen use professional equipment from a well-known Swiss company and give a guarantee for the repaired tank, reservoir, tank, gas tank made of plastic.
Plastic containers are made mainly from materials such as polyethylene and polypropylene, it is almost impossible to glue anything to these materials due to their chemical characteristics, and trying to seal a container from these materials is a waste of time. With large volumes of plastic containers from 2 cubes, this type of repair will not help at all, in this case only welding with special equipment will ensure the sealing of the container!

How to fix a crack in plastic?
Usually the problem is solved with a plastic container repair kit, but remember that if you want to use this method for a long time, such a repair will not help you. All capacitive products in 95% of cases are made of two materials - polypropylene (PP) and polyethylene (PE), which in turn have very low adhesion, that is, they are very resistant to chemical attack. Almost no glue is glued to them, and no one patch with glue will provide quality repair, required professional repair with welding!
How to seal a plastic gas tank?
How to seal a plastic gas tank is a serious matter, not every car service has specialists who can restore a plastic fuel tank, and also give a sealing guarantee! You can repair it yourself, for this again you need equipment and a simple building hair dryer is unlikely to save here, where will they give you a guarantee for your repair? Our workshop both repairs and gives a guarantee for the repair of the fuel tank, specialists go to the place of repair, if necessary, by agreement.

at 7:45 If the hole is small. you need to look in construction stores for welding for plastic or liquid plastic in tubes. Welding was tried when two large buckets and a two-bucket basin were reanimated. Now we keep a supply of water in them in case of blackouts. Nothing flows. Only it is necessary to do everything strictly according to the instructions, without deviations.

at 9:02 as an option. You can also try soldering the way bumpers on cars are soldered. A heat gun with additives for heat sealing is used and a reinforcing mesh is also needed. Come to the service station and consult with the master. As far as I have seen such repairs, the process is generally not complicated.

at 13:50 I have the same trouble, although the container is smaller - only 50 liters - last winter I took in water, pulled the container through the snow and lightly hooked an ice floe - a crack of about 15 centimeters. I think to close up with glue for polyethylene.

at 15:07 Maybe a stupid way, but it seems to me that on top of the hole put a cut out plastic circle. Slightly wider holes. And try to solder this circle. As mentioned above, use solder from plastic. It is sold in hardware stores. Soldering only the hole will not help. Checked.

at 7:09 You can also try. Only now, under the plastic "patch", it seems to me, it is necessary to throw a fine mesh - as a reinforcement. There is one for solder. Then, perhaps, the place of soldering will be kept.
Dear guest, stay!
Many people are already making money just by talking on our forum!
For example, like this. Or like this.
You can start chatting on the forum right now. Just log in via Vkontakte or register, it will take one minute.
Any vehicle wears out over time. This applies to all elements of the car, including the car tank. In particular, used cars may have small crack or even a hole in the tank.
Of course, in no case should such a malfunction be ignored, since, firstly, it is very dangerous for the life of the driver and his passengers, and secondly, this is a very costly business (fuel will constantly leak through the hole).
In fact, do-it-yourself tank repair is within the power of any car owner. There are several ways, resorting to which, you can repair the hole in the tank yourself. To do this, he needs patience and a number of the following things: soap, thinner, cold welding, epoxy glue, fiberglass, soldering iron and solder, as well as welding machine with electrodes.
Instructions for action:
1. If the hole is small, then you can repair the hole in the tank with your own hands using ordinary laundry soap. You just need to rub the entire surface of the tank in the area of the defect laundry soap.
2. To use the following method, it is imperative to stop the flow of fuel from the gas tank first. Only after that you can try to close the crack in the tank using cold welding. In the event that it is not possible to remove the gas tank itself from the car, you can again use laundry soap and rub the defect site with it. For a while, the flow of fuel will be suspended. Next, remove most of the soap with acetone and degrease the surface. After that, it is necessary to carefully treat the surface of the tank near the crack. sandpaper. This is done to improve grip. Now you can take cold welding and close up the hole, while capturing the edges for a couple of centimeters.
3. Fiberglass is needed to improve the insulation of the gas tank. Before gluing the surface of the tank with this material, it should be moistened with epoxy glue. Fiberglass is applied exclusively to dried cold welding. This usually takes about fifteen minutes. Experts recommend gluing 3-4 layers of fiberglass to achieve the best effect.
4. If the hole is large enough, it must be soldered. Before you start soldering, you need to completely stop the flow of gasoline and, if possible, drain it as much as possible. After that, the surface around the defect is treated with sandpaper and degreased with acetone. Next, you should tin the hole with tin and a suitable plate of tin, treated with emery. Now you can solder the hole. The soldered place is additionally tinned with tin.
5. To ensure greater reliability, experts recommend additionally welding a hole in the gas tank, after completely expelling fuel vapors from the unit. To do this, put it on the exhaust pipe and give it a good gas. Now you can weld the hole.

How to seal a plastic water barrel
August 4, 2016November 19, 2017Buckets, basins, barrels and other household equipment are made of plastic. This material is practical, easy to use, but short-lived.
Any drop or mechanical impact can lead to cracks. A container that passes water becomes useless. But it is quite possible to seal a plastic water container so that it will serve properly for some time.
It is quite possible to seal a plastic barrel at home. Consider two options for how to fix holes in plastic barrels and other containers.
Option 1
Required to work the following materials and tools:
- stainless mesh (you can take aluminum, copper),
- scissors,
- soldering iron 100 watts.
Operating procedure:
- Cut off a piece of mesh with scissors.
- We fix the mesh at the site of damage to the depth of the mesh thickness.
- We align it along the seam, moving along the entire plane. At the same time, we solder the mesh with a soldering iron in parallel, hold the free edge with a knife, immediately after soldering we cool it with a heat exchanger (knife) - this important rule so that the mesh does not bulge.
- We introduce the entire mesh into the seam using this method.
- At the end of the work, the seam is completely sealed and reinforced, which gives it a fortress.
- We repeat the procedure with reverse side containers.
VIDEO INSTRUCTION Option 2
If you have to repair a container with water under pressure, you can resort to another method.
For work you will need:
- flexible plastic patch
- building hair dryer,
- protective gloves.
Operating procedure:
- We wipe the area with damage, remove dirt.
- We begin to heat with a hairdryer at low power so as not to burn a hole, a place with a defect.
- We heat the patch with a hair dryer from the side that will be adjacent to the crack. We heat already at a higher power.
- We apply a patch to the place of damage and continue to warm up with a hair dryer, adding more power. Wear protective gloves on your hands to avoid burns. It is important not to overheat the surface.
- We smooth the patch with our fingers and wait for it to cool. We pour water and check the quality of work.
Final sealing and smoothing of irregularities on a repaired plastic tank 
We close up cracks on the tank RELATED VIDEO The first method proved in practice the greatest efficiency. The second is more suitable as a temporary measure.
How to seal a plastic tank or a barrel for water - the choice of an epoch
If the defect in the plastic container is small, you can use epoxy glue. A two-component epoxy adhesive will effectively solve the problem of a leaky plastic tank.
Highly resistant to moisture and chemicals, polymerizes in just 1 hour, non-flammable.
Need to cut off right amount glue, knead with clean hands until a homogeneous mass is obtained, fashion a cone from it and insert it into the opening of the tank. Hold securely for a few minutes.
Then you need to wait 2 hours, after which the container can be operated.
Features of epoxy adhesive "Contact":
- restores the shape of products, and also hermetically fills voids,
- is not afraid of not only water, but also oils, solvents,
- the repaired tank can be used at temperatures from -40C to +150C,
- within 3-5 minutes, the adhesive can be corrected, and after an hour it can be cleaned, turned and subjected to other mechanical influences,
- The adhesive is sold ready to use.
The cost of this composition is from 150 rubles per pack of 50 g.
Adhesives "General Purpos Permapoxy PERMATEX" (from 314 rubles per 25 ml) and "Plastic Weld Permapoxy PERMATEX" (from 320 rubles per 25 ml) also have similar properties.
Epoxy adhesives can be purchased at most hardware stores, as well as online.

How to fix a hole in a tank
A common problem with used cars is a crack or hole in the gas tank. Ignoring this defect is not easy expensive, because gasoline will leak, but dangerous. There are several ways to close a hole in a tank. 
- - laundry soap;
- - cold welding;
- - acetone;
- - fiberglass;
- - epoxy adhesive;
- - soldering iron;
- - solder, tin, soldering acid;
- - welding machine and electrodes.

Repair of plastic tanks can be divided into 2 types: extrusion and bar (soldering with a hot air gun). Other repair methods are not effective (glue, sealant, foam, etc.).
Soldering gasoline and diesel tanks (gas tank) has its own characteristics. The gas tank from special equipment must be removed from the car before repair. Some gas tanks can be repaired directly on the car, it depends on the nature of the damage and the location of the fuel leak.
Polymer water tanks do not require special preparation during restoration, they must be drained, the damage site must be protected from liquid ingress and cleaned of mud deposits (if any).
Extrusion is performed using specialized equipment. Loaded products are repaired using this method (gas tanks of tractors, trucks and cars, tanks with a volume of more than 0.5 cubic meters and tanks operating under pressure). Products after welding do not lose their operational and strength properties - the service life after repair is unlimited.
hot air welding(with hot air gun and plastic additive) less effective method, usually they cook not heavily loaded plastic parts. The service life after soldering is from 1 month (depending on the load). This method, in view of the overheating of the repaired area, is not as durable as extrusion, but its undoubted advantage is its lower cost.
Professional restoration of a plastic tank is carried out as soon as possible, if necessary, with the departure of a specialist welder to the place of work. Water tanks, fuel tanks, plastic expansion tanks, vertical tanks, storage tanks, plastic containers of large volume, as well as containers for reagents and other chemical compositions.
Most modern cars, tractors, construction equipment are equipped with plastic fuel tanks, which for a number of reasons break through, crack and break. The cost of gas tanks is quite high, plus the order and delivery of the product can take a long time, the price of work allows you to avoid high costs and restore a damaged gas tank with minimal losses. Soldering fuel tanks takes about an hour of your time. An example of welding a fuel tank is the repair of the gas tank of the JCB excavator, shown in the first photo, the tank was pierced by iron fittings, after restoration, the properties and shape of the gas tank remained the same, the equipment runs smoothly.
To weld a gas tank (fuel tank), the customer must provide certain conditions - the tank must be drained, dried from fuel (open the neck and other outlets for several hours, keep it open during transportation for the release of gasoline or diesel fuel vapors). We solder gas tanks for trucks and cars, snowmobiles, tractors, trucks, buses, truck cranes and other special equipment.
Self-restoration of polyethylene fuel tanks is impossible if you are looking for something to seal a plastic container with - do not try, there is simply no glue for polyethylene and polypropylene, and manufacturers claiming that glue or sealant can seal a crack in these materials are cunning. Polyethylene or polypropylene are repaired only by welding, if a guarantee and tightness of fuel tanks are needed, then it can be achieved exclusively by extrusion welding. There are no special conditions for soldering a plastic water tank, it must be dry. Wondering - how to seal a plastic tank? - take your time! Due to a number of properties, polyethylene and polypropylene containers do not stick together, sealants, glue and epoxy resins will not help you in solving this problem, and the deterioration of the quality of the surface due to unprofessional repair can increase the cost of subsequent work to restore the product (see photo 3).
A plastic fuel tank is repaired by welding polymers using a welding extruder. Modern plastic containers are made from high quality polymer raw materials. Welding technology makes it possible to repair containers and gas tanks made from almost all types of raw materials. Polyethylene is usually used as the basis for polymer containers, it is known for its resistance to fuel and chemicals, as well as to shock and external loads. Polyethylene containers are distinguished by their durability in use, storage in polymer containers food products and drinking water safe for human body, this is due to the fact that polyethylene does not emit toxic substances and practically does not decompose. Due to the unique chemical and mechanical properties polyethylene and polypropylene, many manufacturers of agricultural, construction and special equipment have adopted polymer capacitive equipment for re-equipment to replace obsolete metal ones.

However, the owners of the corresponding containers are spared their characteristic shortcomings. These disadvantages include a certain fragility of the material.
Under the influence of various external factors, careless impacts, sharp or heavy objects, and if certain heavy objects fall directly into an open tank, when a hydrodynamic shock is created, such tanks can be damaged.
Damage can be either very small and pinpoint, such as from a prick with a sharp object, or extensive, which appear in large cracks that can break structures almost in half.
Such a spectacle is extremely deplorable and especially unpleasant when it comes to the largest reservoirs, since their price is not so small. However, it is not necessary to discard the entire structure when such a problem occurs.
There are opportunities for efficient and convenient restoration of tanks with a full return to their original functionality.
Material Features
Many are accustomed to the fact that they consisted of an extremely slippery and glue-resistant material. It is called polyethylene, however, when repairing, it is necessary to clarify as accurately as possible the specific material from which the corresponding container is made.
In fact, containers can be made from three types of plastics. First of all, of course, it is worth talking about polyethylene. This material perfectly combines hardness and ductility, which greatly simplifies the procedure for its processing.
Polyethylene low pressure well retains its functions and characteristics in the range from -50 to plus 80 degrees Celsius.
Tanks of increased hardness, which is felt even when touched, are most likely made of polypropylene. It is extremely tear-resistant and has high rigidity.
Polyvinyl chloride structures are not operated at temperatures below zero and above 60 degrees Celsius.
In addition, such blocks tolerate contact with chemically aggressive environments well at sufficiently high levels of hardness and strength. Usually information about the material is indicated directly on the tank itself.
Based on knowledge of the material itself, the very principle of restoring a specific container is chosen, there are a number of specialized technologies by which the restoration is carried out.
Of course, first of all we will touch on polyethylene containers, which are the most widespread.
Many are accustomed to the indispensability of plastic adhesives and epoxy compounds. However, in the case of polyethylene, they are completely useless.
Small cracks and damage can be repaired with bituminous waterproofing tapes. Another possibility for gluing polyethylene tanks is the use of BF-2 and BF-4 glue.
This substance has the ability to dissolve external structures and ensure its adhesion to materials. Of course, in this case, it will be necessary to clean all the relevant areas as carefully and efficiently as possible, as well as prepare patches from plastic pieces.
In this case, surface preparation, degreasing and ensuring maximum adhesion are key to effective work glue.
Polypropylene plastic tanks can be repaired by taking fiberglass patches and pouring molten polymer from them with an appropriate glue gun.
In this case, cleaning is also required, and in addition, additional heating of the damaged area with building hair dryer. Always take into account the pressure of the water itself from the inside, calculate the required amount of patch and the required adhesive material for a secure fit.
Extremely effective method which perfectly copes with any kind of plastics is welding.
Considering that materials are freely capable of passing from a solid to a viscous state, it is quite possible to try to melt the plastic to a certain depth, and then simply fill the damaged area with the same heated plastic or specialized bundles to a certain depth.
Of course, in this case, extremely thorough cleaning of the surface is also necessary. In addition, it is desirable to completely empty all tanks on which restoration work is carried out.
