National Fuel Gas Code - Schedule 40 Steel Pipe Third-Party Certification

Fact Sheet April 13, 2016

AGA has determined that third-party certification of Schedule 10-40 steel pipe is not justified nor necessary to help ensure a safe gas piping system when installed in accordance with ANSI Z223.1/NFPA 54, National Fuel Gas Code, 2018. The AGA position is based upon an examination of the ASME and ASTM standards referenced by the National Fuel Gas Code for Schedule 40 steel pipe and its safe record of use in natural gas distribution systems within the operating pressures allowed by the National Fuel Gas Code. AGA has published the attached fact sheet to help explain the Code’s requirements and acceptability.
