PE-AL-PE Multilayer Pipes and Fittings for Gas, Indoor Use

The PE-AL-PE multilayer pipes and fittings are specially designed to form an indoor gas piping system. They are composite pipes constructed with 5 layers of materials by co-extrusion technique. Inner and outermost layers are PE, central layer is overlapped welded aluminum, and between them are adhesives. This forms a construction of PE-Adhesive-Aluminum-Adhesive-PE. The PE-AL-PE pipes can be installed for transporting natural gas, LPG, coal gas and other gases, with the maximum allowable working pressure up to 0.4Mpa.

PE-AL-PE multilayer pipes and fittings from Kingbull are all made to GB/T 18997.1-2003 and ASTMF1282 standards. They have gotten the competitive edge in performance with similar foreign products.
