Pipeline Safety: Use of Polyamide-11 Plastic Pipe in Gas Pipelines

Request for comments.
The Office of Pipeline Safety (OPS) seeks public comments on two petitions for rulemaking filed by Arkema, Inc. The petitions request changes to the gas pipeline safety regulations to increase the design factor for new polyamide--11 (PA-11) pipe and to allow use of PA-11 pipe for systems operating at up to 200 pounds per square inch gauge pressure (psig). These requested changes will allow the use of PA-11 pipe in gas pipelines in place of metal pipe.
