Gas Poly

Gas Poly Piping. This polyethylene pipe is commonly called gas poly piping because of its nearly exclusive use by the natural gas industry for is distribution lines. This is due to several of its characteristics. It has excellent diffusion resistance. It can be installed with bends over uneven terrain in continuous lengths without additional welds or fittings. It is extremely resistant to scale build up, and is impervious to most aggressive chemicals and corrosive elements. Its exceptionally smooth inner surface offers minimal resistance to flow over the life of the pipe. This pipe can be joined by a several methods, but heat fusion is preferred. Polyethylene pipe can also be joined with mechanical and flanged connections.
