Natural gas riser

A weldable riser is composed of high density polyethylene pipe.

Inside, the connection end is protected by a metal pipe.

The connection end without a protective anode is fitted on the outside with an embossed tube with slots to collect and evacuate any accidental leaks of natural gas.

Natural gas service connections (‘Risers’) are used to bring natural gas pipes buried above ground to allow access to the gas flowing through them. Once the natural gas service header emerges from the ground, a valve is usually threaded onto it to control the flow of natural gas ahead of the meter or regulator.
