Plastic pipes for gas lines get a new safety standard

US pipeline regulators have confirmed a new safety standard for plastic pipes used in gas lines. This means gas companies can now use updated polyamide 11 and 12 fittings, which are more modern versions of the plastic materials already in use.

The US has a vast network of gas pipelines, and many of them are old. Replacing aging metal pipes with plastic ones is a common way to upgrade infrastructure and prevent leaks. This rule change means that pipeline operators can use the newest versions of these plastic materials, which are often more durable and easier to install. It removes a small regulatory hurdle for companies looking to modernize their systems.
