The aluminum-plastic composite pipe has good thermal insulation performance, and the inner and outer walls are not easy to corrode. Because the inner wall is smooth, the resistance to fluid is very small; and because it can be bent at will, it is convenient for installation and construction. As a water supply pipe, the aluminum-plastic composite pipe has sufficient strength. If the lateral force is too large, it will affect the strength, so it should be constructed as an open pipe or buried in the wall, or even buried in the ground (the aluminum-plastic composite pipe can be buried underground, for example, the pipes used in floor heating are aluminum-plastic composite pipes). The connection of the aluminum-plastic composite pipe is a ferrule type (or a compression type), so in the construction, one must pass a strict pressure test to check whether the connection is firm; the other is to prevent frequent vibration; Install the amount so as not to pull off.
