Metal-plastic pipes have characteristics that are not inferior to either plastic or metal pipes, at the same time, it is very easy to assemble a water pipe from them, it is enough to see how it is done once. Next, it will be described how the connection of metal-plastic pipes is made.
First of all, you need to figure out what you need to work. Naturally, the pipes themselves are needed. They are sold in skeins, and in appearance they resemble white hoses used for watering. Diameters can be as follows: 16, 20, 26, 32 and 40 millimeters. You must decide which diameter is best for you. The connection of metal-plastic pipes for a private apartment water supply system is usually carried out using pipes with a diameter of 16 or 20 millimeters. The sale of this type of material is carried out by meter, so it is worthwhile to determine in advance the required length of the water supply. You are unwound with one whole piece exactly as many meters as required. The next thing you need
is fittings, which means couplings, tees and elbows. Fittings are selected depending on the
diameter of the pipes. It is worth noting that if you need to connect metal-plastic pipes with metal, then you must purchase couplings and elbows. You only need to clarify the diameters of both pipes in the store so that the seller issues adapters of the right size.
If you are interested in joining metal-plastic pipes, then you need a gauge designed to slightly increase the diameter of the pipe, so that the fitting cone will fit freely into the pipe, and the gaskets will not be subject to strong pressure. If you do not calibrate, there is a high probability of a gap in the gasket. Another important tool that you will need for your work is a
hacksaw for metal (or special scissors). You should also pick up keys of different sizes to suit your needs.
To perform the connection of metal-plastic pipes, it is necessary to perform a number of simple manipulations. First, put a nut with a crimp washer on the end of the plastic pipe. After that, with the help of a caliber, it is required to make the pipe diameter a little larger, for which it should be screwed into the pipe lumen with uniform movements in a circle. A fitting cone can be inserted into a calibrated pipe. Next, you need to tighten the nut, which will allow the washer to slowly squeeze the pipe.
Fittings and pipes can be mounted using threaded connections or press systems. The first case involves the use of a sharp cutter, calibrator, as well as an adjustable wrench. Press connection of plastic pipes involves the use of special equipment. This process is much simpler, but the connection is less reliable. For work, you will need to use press tongs. The press fittings have a special plastic insert having a spacer 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 supply system by cutting pre- sized pipe sizes, as well as picking up fittings.
