tool. To date, many people have to replace the heating or plumbing system with a new one, because the metal communications have become rotten or clogged. Many people prefer to change pipes to metal-plastic ones, they are smelted, or again to metal ones. As practice shows, stacking of polyethylene pipes is the most affordable and easy option.
Installation of polyethylene pipes with their own hands will require the availability of such tools: pipe shears, soldering iron, gas keys, flax. The soldering iron is sold with a set of nozzles for various diameters. Scissors, if desired, can be replaced with a jigsaw, although it is better they.
When cutting the pipes with scissors, the edges are straight, without jags and burrs. A gas wrench will be needed when mounting the connecting elements from metal to polyethylene.
Despite the variety of other means, flax is used for reliable pipe connection, because such connections are always dry. The tool for installing polyethylene pipes can be bought at any construction shop. A soldering iron with a set of attachments is often sold together with scissors in one set, specifically they will not have to be searched for.
What should I do before starting work?
When everything is available, you can start creating a project for a water, gas, sewer or heating system, depending on what is needed. The technology of laying polyethylene pipes is quite simple. Let's consider the installation of such pipes using the example of a heating system.
Calculation of the number of required materials should be carried out depending on the number of drops, angles. First, it is necessary to close all water supply valves, then arrange all available materials according to the project and proceed to the installation.
It is necessary to start laying from the boiler, if the house has autonomous heating. It is required to determine the dimensions and produce a spike of scraps of metal pipes with connecting fittings. The connection of polyethylene pipes is also made by soldering iron. It is not difficult to learn how to use the soldering iron correctly. There are many technical nuances that include the installation of polyethylene pipes, the video on our portal will help visually present the described operations.
Do the installation correctly
The technology of installing polyethylene pipes is as follows: from the edges of a pipe of the necessary length, previously cut with special scissors, at an angle of 45 degrees, the chamfer is removed. After that, the prepared edge is inserted into the soldering iron on the nozzle at the same time as the connecting fitting, which is put on the other nozzle.
For a few seconds, the heating occurs simultaneously, after which the heated parts are quickly removed from the nozzles and connected. The main thing is simultaneous heating and the necessary temperature of the soldering iron. Usually put 270 degrees Celsius. After this, the compound should be allowed to cool for a couple of minutes. Do not use forced cooling, because this will affect the quality of the seam.
It is necessary to pass along the entire perimeter of the completed project, consistently connecting pipes with fittings and radiators. The spike ends at the boiler on the output element. After that, the system is filled with water and the boiler is turned on. It is necessary to methodically inspect all connections for leakage. Then put the required pressure on the boiler, and let the air out of the radiators.
