Traditionally, black iron schedule 40 gas pipe was coated in water proof green teflon coating. This product, known as “Green Pipe”, was expensive to produce and could not be cut to length on site. Nowadays, consumers have much more affordable options for under ground gas piping. Yellow Polyurethane under ground gas pipe comes in large spools and can simply be rolled into a ditch to your desired location. This is the same product used by the major gas suppliers. A tracer wire must be layed in the ditch next to the poly gas pipe so the gas line may be easily found at a later date. Woven hardened steel gas risers must be used at each end of the poly under ground gas pipe to protect the pipe as it leaves the safety of the ditch. Poly Gas pipe is ideal for longer under ground gas piping lengths as the footage is relatively inexpensive, the majority of the cost involved with poly piping is from the steel risers.
Although local codes may vary (check with your local Gas Contractor), generally under ground gas piping must be sleeved in conduit if it is to pass underneath a concrete or masonry slab. The purpose of the conduit is not to protect the pipe as much as it is to allow a gas bubble to escape safely rather than dangerously build up underneath the slab. Hiring a knowledgeable Gas Piping Specialist is crucial when planning any under ground gas piping. The sizing requirements vary depending on the product used, and piping under ground presents a whole new set of ruels and codes to follow.
