Abstract
This final rule amends the design factor and design pressure limits for natural gas pipelines made from new Polyamide-11 (PA-11) thermoplastic pipe. Together, these two changes in the regulations allow pipeline operators to operate certain pipelines constructed of new PA-11 pipe at higher operating pressures than is currently allowed for other plastic pipe materials.
