The connection of plastic pipes is a reliable and easy way to quickly install a water pipe. While such tubes are longevity in terms of durability, copper pipes, and in terms of strength, are plastic, they remain a very accessible material for the replacement of obsolete water supply systems, which is due to the simplicity of the connection technique, as well as moderate cost.
For the production of plastic pipes, a particularly durable plastic is used, it does not deform, it can not be destroyed. This material is not able to affect the chemical composition of water, can resist salt formations, can not be corroded. Installation of plastic pipes should not be made for heating systems, although a number of modern plastics are designed for use in environments with high temperatures.
At the moment, plastic pipes made of different materials are on sale. As the most popular can be identified polypropylene, polyethylene, as well as polyvinyl chloride. Pipes made of different plastics require different technologies for connection. Before you begin the installation of plastic pipes, you need to determine the configuration of the upcoming wiring, as well as prepare pipes of different lengths and the required number of fittings. In addition to specialized equipment, for joining pipes, you will need a tape measure, rags, markers and the like. The installation of plastic pipes is carried out using a variety of brackets and fixtures to accommodate pipes on various surfaces. Fasteners are selected depending on whether the pipe is horizontal or vertical. Installation of plastic pipes can be carried out with bends, which will allow to achieve a suitable configuration. In the process of bending, you must observe the measure, because the pipe can crack or burst. Plastic properties depend on which brand of plastic was used for the production of pipes.
It is worth saying that the installation of plastic pipes from polyethylene should not be made close to the wall, it is worth keeping the distance between them and the surface at least two centimeters. While calculating the system, one should look at the properties of linear expansion of plastic under the influence of different temperature regimes, for which it is important in the system to provide a compensating loop. The process of soldering plastic pipes in itself is not complicated, however, it is worth remembering that everything should be done accurately and accurately, as there will be no possibility of correcting the mistakes made.
The cooking process takes place with the use of scissors, as well as a welding set designed specifically for fusion welding of polypropylene pipes. All this is done in four basic steps: cutting; heat; compound; cooling.
Installation of plastic pipes can be carried out and by means of "cold" welding, which is done by using a special aggressive glue. Pipes should be cut and prepared, as for welding. The glue must be applied to both parts, after which they must be quickly connected and pressed as much as possible for 15 seconds. The system should be in a state of complete immobility for a little more than an hour, after which it can be fed with water. On the strength of such a connection is not inferior to welding.
