What is the maximum pressure allowed for LP gas when using plastic gas pipe?

The maximum pressure allowed for LP gas when using plastic gas pipe is 30 psig. This limit is in place to ensure the safety and integrity of the gas piping system. Plastic pipe has inherent characteristics that may limit its ability to withstand higher pressures without risking rupture or leakage.

At pressures exceeding 30 psig, the material properties of the plastic could be compromised, potentially leading to hazardous situations such as gas leaks or failure of the piping system. Regulations and standards, such as those from the National Fire Protection Association (NFPA) and the American National Standards Institute (ANSI), have established this maximum pressure to provide a safe operating environment.

Moreover, it’s important to note that different materials, such as metal piping, can handle significantly higher pressures than plastics, which reinforces the importance of adhering strictly to designated limits according to the material used in the gas piping. Always consulting local codes and guidelines is essential for ensuring safe installation and operation.
