New Hailong multilayered pipe is five-layer composite pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. The inner layers and outer layers of mutilayered pipes are made from HDPE or Pex-b materials, which are tightly boned with middle aluminum layer by using a special glue.The aluminum core is absolutely diffusion tight;it reliably prevents oxygen/gases from permeating into pipe.

New Hailong multilayered pipes are wildly used in plumbing systems for cold and hot water supply, underground heating systems, solar water systems, gas systems, etc.
