Dear Mr. Maver:
By letter of July 22, 1974, you asked if the use of fiberglass vent stacks on low or high pressure relief valves would violate 49 CFR Part 192. You further asked if Section 192.321(a) would preclude the use of plastic pipe for the same purpose.
A fiberglass vent stack must comply with requirements in Part 192 for plastic pipe. As a pipeline material, “fiberglass" is actually a thermosetting plastic material which is reinforced with fiberglass.
The restriction in Section 192.321(a) that plastic pipe may only be used below ground applies to pipe made from either thermoplastic or thermosetting material, whether reinforced with fiberglass or not. Thus, fiberglass may not be used for vent stacks above ground.
We hope that this provides a better understanding of the applicability of the Federal requirements. Thank you for your interest in pipeline safety.
Sincerely,
SIGNED
Cesar DeLeon
