Unlike above-grade gas piping installations that require metallic piping, underground systems need to perform in harsh and corrosive environments. Metallic pipe installed underground requires additional and costly materials to protect the pipe. Polyethylene gas piping systems are specifically engineered and certified for the underground environment. To provide a true underground gas piping solution, Gastite® has partnered with Continental Industries, Inc. to bring you ConStab I.D. Seal®, fittings, anode-less risers and polyethylene tubing (PE). These components assemble in minutes to form a complete underground gas piping system, which offers the flexibility and simple fitting assembly you have come to expect from Gastite®.
