  Repair of steel pipes. Repair of pipes of water supply in the apartment Repair of steel pipes

If there was a need to find a heating pipe repair organization, you came to the right address. The Center for Personal Services specializes in the repair of water pipes and heating.

The presence of a huge variety of pipes in the plumbing market, from polypropylene to copper, has led to the need to find a way to repair pipes of various materials and diameters. While some failures are minor and can be repaired quickly, repairing pipes hidden in a wall in an inaccessible place may require a lot of effort and a lot of time, and repairing sewer pipes may not be possible at all.

In many cases it is possible, but one of the most inconvenient and time consuming. And yet, in most cases, metal pipes are a distant past and may require a complete renovation of bathrooms and toilets with the replacement of pipes.

The best choice for high-quality work of heating. And the repair of copper pipes is much easier to carry out than the repair of pipes made of metal. In this case, for example, soldering a pipe with a specialized welding machine is available.

Although the quality of the pipes themselves can be quite high, their repair is the most difficult, especially if we talk about repairing the pipe under the bathroom. The complexity is due to the peculiarity of the device soldering tools for the pipe.

From plastic it is possible only with the help of their partial replacement. If the pipe is damaged too much, then it will have to be changed entirely.

This is the lot of plumbers of the old school. Although such repair is possible in principle, it is better to replace cast-iron pipes with modern ones.

Repair of a pipe of a heat-insulated floor and other metalplastic and polyethylene pipes is similar in its own way. Breakdown with a drill or an accidental breakthrough at the point of inflection can be repaired with special parts. Repair of a metal-plastic pipe in the wall can be a particular difficulty.

Fortunately, the number of call repair masters can be reduced to a minimum. First of all, be careful when drilling holes in the bathroom, in the immediate vicinity of the pipes. Use coarse filters and water hardness. Even this minimum of rules will reduce the necessary pipe repair to a minimum.

Both pipes and any plumbing has a very inconvenient property to flow at the most inappropriate moment. And it's good if this happens in your presence, and if you are at work and at home there is no one? Alas, you will definitely flood your neighbors, and an impressive hole will form in the family budget.

Nevertheless, let us imagine that you are still at home and here it is - a sharp leak, and such that water splashes out like a fountain. What to do?

Water overlap

First of all, of course, you need to shut off the water supply as quickly as possible. What kind of valve you need to turn? It depends on the specific type of sewage in your house or apartment.

Often the desired valve is located next to the pipe or plumbing, where a leak is found. Sometimes it is a common valve that supplies water to the whole apartment or house.

Look for the right valve, looking through the pipe that supplies water to the bath or sink. In addition, there are separate valves on small pipes, to which washing machines are connected.

Faucet to supply water to the toilet

Is the right valve found? Turn it counterclockwise immediately to shut off the water. When the water pressure is stopped, it's time to start the repair.

Drain water

The leakage is temporarily stopped, but it is still too early to start repairing - all remaining water should be removed from the plumbing system.

As a rule, this should (if you have not already done so) cut off the water supply throughout the apartment.

Now open the tap that is below all other taps. Then gradually open other taps, thanks to which air will be supplied to the plumbing system and the water will merge faster.

How to quickly repair leaking pipe

The water is blocked and drained - it is time to patch up the pipe, which began to flow inappropriately.

When such a copper pipe begins to flow, you need to start repairing it immediately.

Let's see how this can be done.

  1. If there is water in the pipe, it should be drained.
  2. In the place where the pipe is leaking, put a thick piece of rubber or cut such a piece from an old garden hose. Such a patch should be larger than the leakage zone by 5-6 centimeters in each direction.
  3. Fix the patch with a wire or plastic zippers.

How to quickly repair cracked pipe

  1. Hose clamps and a fragment of a conventional garden hose.
  2. Rubber or a piece of garden hose, tightly tied with wire.

Protective sheath and neoprene rubber allow temporarily forget about leakage

  1. Tighten the clamp with the bolts.
  2. Pipe clamp.
  3. Neoprene rubber.

Specialized plastic protective sheath for the repair of cracked pipes. To use it, place the shell exactly in the center of the crack and secure in place.

A more versatile and reliable option is to purchase a special protective sheath for pipes that will last much longer than your old garden hose. However, this is still a temporary solution and the pipe will have to be replaced.

How to repair cracked water pipe

If the steel water pipe is cracked, then it must be overhauled. For this, the cracked pipe fragment is replaced with a whole.

If steel pipe cracked

To connect this fragment with a pipe, as a rule, a fixing coupling is used.

To overhaul a metal pipe that has cracked, it is necessary to remove the cracked fragment and install a new one. Fixing couplings are applied to fastening.

  1. Coupling for connecting pipes made of steel.
  2. Incision in the tube.
  3. Remove both pipe fragments to the right and left of the incision.
  4. Use a pipe wrench to hold the fittings and unscrew the pipe with another wrench.
  5. New pipe sections.
  6. Assembled coupler.
  7. The coupling nut is screwed onto the pipe.
  8. The second coupling nut is also screwed onto the pipe.
  9. The coupling nut is screwed onto the coupling nut.

In this case, the steel pipe segment is replaced with its galvanized version.

Repair of cracked copper pipe

If the copper pipe is cracked, the repair is done in the same way. The damaged fragment is cut out, and a coupling is mounted instead. Sometimes it is necessary to cut the entire fragment to the nearest connection, especially in the case when the coupling is not enough to cover an overly large crack.

To overhaul a copper pipe, the damaged segment is cut out, and a special coupling is installed instead.

  1. Disconnect the pipe end from the fitting.
  2. The damaged segment needs to be cut.
  3. Solder the new fitting.
  4. Solder the new coupling.
  5. Add a new pipe segment if the damaged segment is longer than the coupling.
  6. Water from the damaged part of the pipe must be drained.

Such a cracked and swollen copper pipe requires an immediate overhaul or a complete replacement.

Change the cracked plastic pipe

Repairing a cracked plastic pipe is somewhat more difficult. As a rule, it is not possible to remove the plastic pipe from the fitting, so a cracked segment should be cut out of the pipe, after which a new segment should be installed.

At the same time, the new segment is established thanks to the couplings, which are mounted on a special glue.

The overhaul of a plastic pipe involves cutting out a damaged segment and replacing it with a new segment, which is mounted with clutches “planted” on glue.

  1. Cut a long enough piece of pipe in order to install both the new piece and the two couplings.
  2. Coupling.
  3. New pipe fragment.
  4. Coupling.
  5. Cut a piece of pipe.
  6. Insert a new piece containing two couplings and a short pipe segment.

Replacing a plastic pipe segment placed under the sink. Of course, working with plastic is much easier than with steel or copper pipes.




  Steel pipes are usually used in utility or technical rooms. Often they have a large diameter, and this feature makes it possible to carry out repairs in a peculiar way. What to do if there is a fistula in the steel pipe? Apply the following options:
  • repair with the help of a bolt: the place of the fistula is drilled, threaded and screwed up;
  • elimination of leaks using a temporary bandage or clamps with a gasket (impose, if damaged
  • the site has a significant area);
  • repair with adhesive bandage - glass cloth impregnated with sealant wraps the damaged area (impose at least 6 layers);
  • flange connection.

The system is previously shut off and the coolant is drained. Repair work is carried out on a dry and cooled area.

At the same time it is extremely important to comply with the established norms and rules for carrying out repairs.

It should be noted that the independent performance of these works can lead to serious consequences during the operation of communication systems. Virtually any malfunction in the operation of pipelines leads to the fact that being in a room becomes not very comfortable, and also material and moral damage can be caused to people living in the neighborhood.

Repair of pipes in the bathroom

   In the event of a leakage in communication systems where pipes made of cast iron are used, it is possible to carry out routine repairs of these pipes with the help of traditional metal clamps. In this case, the rubber gasket is applied to the pipe in the place where the crack was formed, and then tightened with a yoke. Care must be taken to ensure that the gasket completely covers the crack that has formed. It should be noted that this repair of pipes for heating or water supply is temporary, so for a more serious repair it is necessary to use a welding machine or completely change the pipes.

Repair of pipes "open installation" to 25DU  - from 2000 rubles.
Repair of pipes "flush-mounted" to 25DU  - from 2500 rub.
Repair of steel pipes for welding "open installation"  - from 2500 rub.

There is also a way to repair cast iron pipes, when their socket is sealed with asbestos cement. It also uses asbestos fiber, which is mixed with Portland cement. It must be borne in mind that the brand of this cement can not be lower than four hundred. In addition, the sealing of the sockets should begin with the fact that the hemp tar tar bundle is pre-applied to the places where the pipe joints are located.

Repair of steel pipes in the bathroom

   Damage to steel pipes, as a rule, is associated with the occurrence of fistulas - foci of pitting metal corrosion.

To eliminate these damages, it is necessary to carry out a number of operations:

  • The movement of water through the valve is blocked.
  • Fistula is expanding through the use of a drill or core.
  • Using a tap, a thread is cut and a bolt is screwed into a hole that has been prepared.
   In some cases, fistula has an oval shape. You cannot use the method described above here. To solve the problem, it is necessary to impose a temporary bandage that has rubber sealing gaskets. This bandage is tightened with bolts or clamps. In addition, such damage can be eliminated through the use of glass fiber based on epoxy glue.

When gluing pipes, they must be pre-cleaned of rust and dirt using a file, sanding paper or a brush. Then the ends of the steel pipes should be rubbed with gasoline or acetone, and then they need to dry for about fifteen minutes.

Repair of copper pipes for heating and water supply

   Copper pipes, despite their durability and functionality, are subject to wear and corrosion, which leads to the need to repair these pipes. Most copper pipes have damage to the bend, which can be eliminated through the use of sealant. In the event that damage is serious, then it is necessary to replace the copper pipe, which will avoid problems in the future.

In the event that there is a separation of the copper pipe, soldering can be used, which is divided into two types: high-temperature and low-temperature. When high-temperature soldering is carried out, a solid solder is used, which makes it possible to increase the service life of copper pipes. At low-temperature soldering, special low-temperature solders are used.

When installing copper pipes, it is necessary to remember that there are certain parameters of their bending. For example, in the event that the diameter of a copper pipe does not exceed 1.5 cm, the bending radius should be 3.5 diameters of this pipe and more.

Repair of PVC water supply pipes

   PVC pipes are not only fairly durable, but can be used much longer than traditional cast iron pipes. During the repair of PVC pipes, glue is used, with the help of which they are connected to the socket. The ends of the sockets and tubes are prepared by stripping and degreased with a solvent.

In the case when PVC pipes have no axial movement, you can apply repair in an oblique joint. To do this, use a hacksaw, which is cut at an angle of forty-five degrees, both in the workpiece and in the pipe. Then the pipes are connected, pressed and fixed with a coupling.

It is possible to carry out surface repairs of PVC pipes, in which a bandage of adhesive tape is applied. In addition, in this case, you can use a universal adhesive designed for bonding plastic surfaces. Before carrying out this repair, pipes are cleaned and degreased. Similarly, quite often repairs are carried out in the bathroom.

PVC pipes can also be repaired by welding, which is carried out with a nail or knife, which is preheated to a red-hot state. Under the influence of high temperature, the edges of pipes made of plastic melt, which leads to the filling of existing holes. By installing the water supply or heating pipes, you can weld the pipe parts to each other. To do this, they need to hold over the burner fire. It should be remembered that a material such as PVC cools quite quickly, so all the work must be carried out promptly.

The cost of repairing pipes

  The cost of work related to the repair of heating pipes, water supply, sewage, depends on which pipes need to be repaired, the complexity of these works and the equipment used. The cheapest is the temporary repair of pipes, which uses fairly simple means.

What is the most common cause of damage to steel pipes?
  Most often, steel pipes are damaged by so-called fistulas, which are formed as a result of pitting corrosion.
Can I repair a steel pipe with a fistula?
Damaged pipe should be replaced. However, if for some reason it is impossible to do this at the moment, temporary repairs are carried out. To do this, first block the flow of water to this section of the pipeline, and then expand the fistula formed on the pipe using a core or drill. After that, using a tap, a thread is cut and a bolt is screwed into the prepared hole.
  If the fistula is oblong in shape and repair is impossible in the manner described, it is possible to eliminate the leak by applying a temporary bandage with rubber sealing gaskets. Bandages are screwed on one or both sides. The same can be done with clamps.
  You can impose adhesive bandage compound, which is based on fiberglass impregnated with epoxy glue. The adhesive bandage also allows joining pipes together.
  Fiberglass cut into ribbons, the length and width of which depend on the diameter of the pipeline and the size of damage to the pipe. The tape must be of such length that the tube can be wrapped with it at least 6 times. The width of the tape should be greater than the diameter of the pipe by about 30-40%.
  To the edges of fiberglass do not crumble, the edges of the cuts are impregnated with BF-2 glue. After that, impregnate the tape with epoxy glue. To do this, put glue with a spatula evenly on one side of the tape.
How to temporarily repair a leaking pipe?
  Water is drained from the pipe, a piece of rubber is put in place of the leak, it is clamped with hose clamps, wire stranding (fig. 1) or pipe clamp (fig. 2).

How to perform a major repair of copper pipe?
  A section is cut out of the cracked pipe and a clutch is put in its place. If the crack is large, the pipe section is removed before the first joint (Fig. 4).

Fig. 4. Overhaul of copper pipe: a - damaged pipe; b - the repaired pipe; 1 - damaged area; 2.4 - fitting; 3 - coupling.

How to perform a major repair of plastic pipe?
  It is impossible to remove the plastic pipe from the fitting, so it is necessary to cut out the damaged section and install a new section with couplings at the ends instead (Fig. 71).

Fig. 5. Overhaul of plastic pipe: a - damaged pipe; b - the repaired pipe; 1 - damaged area; 2.4 - clutch; 3 - new section

How to defrost the pipe?
  To prevent pipe rupture in the event of long-term shut-off of heating in winter, drain the water from it. If this is not possible, the pipe is urgently defrosted. If the pipes are laid inside the house, turn on the heating and allow them to warm up with the room.
  Pipes located outside the house are defrosted using electric heating tape, electric blankets, a hair dryer or an electric heating lamp. You can also use a propane torch with a flame divider.

What tools do you need in your house for temporary and capital repairs of pipelines?
  The following tools will be needed to repair the heating system:
  - flat and cross-head screwdrivers;
  - pliers and pliers;
  - kiyanka;
  - hammer;
  - chisel;
  - adjustable wrench;
  - spanners;
  - pipe wrench;
  - files for metal;
  - electric hacksaw;
  - cable for pipe cleaning;
  - plastic sealing tape;
  - pipe bending device;
  - pipe cutter;
  - propane burner;
  - device for flaring.
