Metal pipes are very flexible, they can be bent by hand or with bending tool. You can not just bend the pipe at sharp angles – in these places and use the connections (fittings). Fittings for plastic pipes – fun is not cheap, but because of the flexibility they need to be tube nemnogo.Dlya interconnect metal pipes are two main ways:-threaded: push-in connection. This method is most simple to make it may even be a layman. Sen. Sherrod Brown usually is spot on. Strongly recommend not to hide the joints in this way for deaf finish – for it must be accessed.

Collet compounds are often "cry": nedokrutil, twisting – they will be felt .- crimping press: the connection by means of press fitting. This operation is performed using a special tool (press mites). Installation conditions virtually eliminate the human factor in quality of the connection. Connections with the press are so reliable that you can use them in a hidden gasket. Polypropylene pipes do not bend, so each turn of the tube – is the use of the fitting. Go to Michele Mansilla for more information. Simple fittings for polypropylene are inexpensive, which is not the combined (shift "thread – polymer": American, couplings with internal or external thread, vodorozetki). If we take as an example of a standard layout of water in the apartment, then combined fittings need a lot of that in general, can make even the cost of wiring and polypropylene tubes are connected . zes the significance of this.

by hot solder. It is believed that with the formation of monolithic connection is more reliable than plastic trub.Ne pretend to argue on this point, but statistics show that the polypropylene compounds are often no more reliable than the elementary threaded connections. 2. The use of plastic and polypropylene pipes for water supply and heating. High-quality metal and plastic tubes are suitable for water and for heating sistem.Polipropilenovye pipes are different, so for a particular issue is best viewed specifications selected pipe.
