Approved and certified by SAI Global and SGS for gas distribution in homes and other buildings, Rifeng Gas System combines Rifeng multilayer pipe and fittings. The continually-welded middle layer of AL makes Rifeng multilayer pipe able to stand Hi-working Pressure and assures no as(oxygen) permeabliity, it's bendable to decrease fitting attached, thus no leakage.

Today's stringent technical standards for gas distribution in homes,makes multilayer pipe a natural choice for compressed air,gas and oxygen supply.In outdoors installations, the pipe's resistance to rupture and other technical properties permit the use of innovative techniques such as "no sand - no dig" intallations.In most applications,even under very tough environmental conditions,the Rifeng multilayer pipe will remain more resistant and safer that a conventional polyethylene gas pipe.
