What does "aluminum plastic composite pipe" 1216-l mean?
Aluminum plastic composite pipe is the earliest water supply pipe replacing cast iron pipe, and its basic composition should be five layers, namely, inside and outside are plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic. Now the domestic aluminum pipe quality leading areas: Foshan region. Famous domestic brands are: HSBC, Fengtai, meifeng.
Aluminum plastic composite pipe has better thermal insulation performance, internal and external wall is not easy to corrosion, because the inner wall is smooth, the fluid resistance is very small, and because it can bend freely, so the installation and construction is convenient. As the water supply pipeline, the aluminium plastic composite pipe has enough strength.
If the lateral force is too large, it will affect the strength, so it should be used for the construction of the pipe or buried in the wall, and even buried. (aluminum-plastic composite pipe can also buried underground, such as floor heating pipe is used in plastic composite pipe) aluminum-plastic composite pipe connection is card sleeve (also card type), so the construction is to pass a stringent test pressure, test connection is solid. Two is to prevent frequent vibration, so that the sleeve loose. The three is the length of the installation should be sufficient volume so as not to pull off.
