Dear Mr. McIntosh:

This is in response to your letter of November 30, 1971 to Mr. F.E. Fulton. The following is our interpretation concerning the use of plastic valves in gas pipeline systems.

The minimum safety standards for the Transportation of Natural and Other Gas by Pipelines (49 CFR part 192) do not include any specifications for nonmetallic valves. Neither do these regulations prohibit the use of nonmetallic valves so long as the valves meet the appropriate requirements of the regulations. Any nonmetallic valve Used in a gas pipeline system would be required to at least meet the requirements in Section 192.143. In the case of thermoplastic Valves, as a means of meeting the requirements of section 192.143, it would be expected that the valves at least Meet the appropriate safety design limitations of Sections 192.121, 192.123, 192.191, or equivalent, and the appropriate sections of the referenced ASTM D-2513 specifications.

Thank you for your interest in pipeline safety.

Joseph C. Caldwell
Acting Director
Office of Pipeline Safety
