Plastic pipes for gas lines get a new safety standard

US pipeline regulators have updated the industry standard for plastic pipes used in gas lines. This means gas companies can now use the latest version of the standard for polyethylene pipes, tubing, and fittings.

For years, pipeline operators had to follow an older version of the standard for plastic pipes, even as the industry developed newer, safer materials and manufacturing processes. This update allows them to use modern materials and techniques without needing special waivers. It should make it easier and cheaper to build and maintain gas pipelines while keeping them safe.
