Connection of plastic pipes.

The availability of more convenient and easy-to-use materials, virtually displaced from the use of the use of cast-iron pipes. But if you still had to deal with this particular design, then a flange is used as a connecting element for the frame. This part is a piece of pipe, the internal diameter of which coincides with the outer diameter of the pipe into which the insert will be made. The connection of these two parts is carried out with the help of welding equipment or clamps. To ensure airtightness, epoxy resin is used. Implementation of the frame in cast-iron water.

And what if the pipe that will be crashed consists of plastic, on which the welding method can not be applied. There are two options:

  • If there is a bell on the pipe, you can use a special rubber adapter, on which the sealant is applied. After this, a plastic pipe is inserted into the adapter and the entire structure is fixed into the socket.
  • If there is no bell, it is necessary to put the rubber adapter on a cast-iron pipe. On top of it, a special adapter is attached, into which a plastic system is then inserted. Its advantage is in the ease of dismantling, if necessary.

For the work on insertion into the plastic pipe, the first thing to do is to purchase special connecting flares with a rubber seal, which will exclude the possibility of leakage. A pipe with a branch pipe is inserted into it. This method is complicated by the fact that it requires the crushing of an entire long pipe into two short ones. This is done in order to install a tee on their joint with each other. Implementation of the frame in cast-iron water.

If this method seems too complicated for you, then there is a simpler option. Prepare a piece of pipe with a branch pipe of the appropriate diameter. A hole is made in the embedded pipe, the edges of which are covered with a sealant. Using clamps, which as much as possible tighten, connect your construction with the pipe.

Cutting into an existing metal plumbing.

If the pipes are metal, but the method that is used in the case of cast-iron pipes is suitable. The flange is self-made, the diameter of which, for a more tight fit, should correspond to the diameter of the pipe into which the tie-in will be made. Implementation of the frame in cast-iron water.

You can use the ready-made tee, which is sold in the store. Even if it is more than the diameter you need, the problem can be eliminated by cutting off part of it that does not have a branch pipe.

For fixing the flange to the pipe it will be necessary to apply to the services of an experienced welder who can do it qualitatively. If, nevertheless, during the operation of the pipes, water leakage was detected - it can be removed with the help of a sealant. The same sealant can be used if, for some reason, there is no possibility to conduct welding operations. For reliability, the construction is additionally secured with clamps.

Use of connection adapters.

Simply put, adapters( fittings) are special adapters. They greatly facilitate the whole process of inserting pipes.

Advantages of using adapters:

  • They are used for fastening pipes from different materials( for example, from metal to plastic and vice versa);
  • Capable of joining structures of different diameter;
  • Convenient in installation, do not require special skills;
