What is the maximum working pressure of Polyethylene (PE) piping?

Polyethylene (PE) piping is commonly used in various applications due to its flexibility, resistance to corrosion, and ease of installation. The maximum working pressure for PE piping is typically determined by its material specifications and the standards set by relevant regulatory bodies.

In this context, the correct maximum working pressure of 30 psi aligns with the specifications for standard polyethylene piping used in various gas distribution and service applications. This pressure rating is significant as it ensures the integrity and safety of the piping system under operational conditions, preventing potential leaks or failures that can arise from exceeding this limit.

While the other options present lower pressure ratings, they do not meet the performance criteria for typical PE piping applications, which can operate efficiently at the 30 psi level without compromising safety standards. A solid understanding of these pressure ratings is crucial for tank setters and those involved in fuel systems to ensure compliance with state regulations and industry practices.
