PEX-B also features an increased resistance to chlorine, making it a good choice in areas where water is highly chlorinated.What's the multilayer pipe?Multilayer Pipe, also called multilayer composite pipe MLCP, or composite pipe, has been widely used for hot & cold water plumbing systems, underfloor heating systems & indoor gas distributions.,etc.Multilayer pipes are a "composite pipe", which are made of composite materials with a five layers' structure. The inner & outer layers are regularly made of PEX/ PERT (or HDPE) material, middle layer is aluminum core, which is welded in a seamless laser welding technology or overlap welding technology. To bond the PEX layers to aluminum layer, a special adhesive shall be used.The aluminum-plastic composite pipe has good heat preservation performance, the inner and outer walls are not easy to corrode, because the inner wall is smooth, the resistance to fluid is small; and because it can be bent at will, it is convenient to install and construct. As a water supply pipe, the aluminum-plastic composite pipe has sufficient strength. If the lateral force is too large, the strength will be affected. Therefore, it should be constructed with exposed pipes or buried in the wall, or even buried in the ground.What types of multilayer pipe can HEWAI provide?
