How and what is the connection of metal-plastic pipes

Metal-plastic pipes have characteristics not inferior to plastic or metal pipes, at the same time it is very easy to mount a water pipe from them, it is enough to see how it is done once. Next, you will learn how to connect the metal-plastic pipes.

First of all you need to understand what you need for work. Naturally, we need pipes. They are sold in coils, and in appearance they resemble white hoses used for irrigation. The diameters can be the following: 16, 20, 26, 32 and 40 millimeters. You must decide which diameter best suits you. The connection of metal-plastic pipes for a private apartment water pipe is usually carried out using pipes with a diameter of 16 or 20 millimeters. Sale of this type of material is carried out by the meter, so it is necessary to determine in advance the required length of the water pipe. You will reel off one whole piece of as many meters as required. The next thing you need is fittings, which are muffs, tees and corners. The fittings are selected depending on the diameter of the pipes. It is worth noting that, if you need to connect metal-plastic pipes to metal pipes, then you must purchase couplings and angles. You only need to specify in the store the diameters of both pipes, so that the seller has issued adapters of the right sizes.

If you are interested in joining metal-plastic pipes, you will need a caliber designed to slightly enlarge the pipe in diameter, so that the fitting cone will fit freely into the pipe, and the gaskets will not be subject to strong pressure. If there is no calibration, then there is a high probability of rupture of the gasket. Another important tool that will be required for your work is a metal hacksaw (or special scissors). You should also choose keys of different sizes, suitable for your needs.

To perform the connection of metal-plastic pipes, it is necessary to perform a number of simple manipulations. To begin with it is necessary to put on a nut with a collapsible washer on the end of a metal-plastic pipe. After this, with the help of a caliber, it is required to make the diameter of the pipe a little more, for which it must be screwed into the tube lumen by uniform movements in a circle. A fitting cone can be inserted into the calibrated tube. Then it is required to tighten the nut, which will allow the washer to slowly squeeze the pipe.

Fittings and pipes can be mounted by threaded connections or press systems. The first case involves the use of an acute torch, a calibrator, and a swivel wrench. The press connection of metal-plastic pipes involves the use of special equipment. This process is much easier, but the connection is less reliable. For work you will need to use a press pliers. The press fittings have a special plastic insert, which has a separating ring, designed to control the relative position of the fitting and the pipe, as well as to insulate the inner layer of the pipe.

According to one of these principles, it is possible to connect a water pipe, cutting the previously required pipe sizes, and also picking up fittings.
