Polyethylene piping systems are limited to vapor service not exceeding which pressure?

Polyethylene piping systems are recognized for their capacity to handle gaseous substances safely, but they do have pressure limitations that must be adhered to in order to maintain safety and integrity. The established limit for vapor service in polyethylene piping systems is set at a maximum of 30 psig. This restriction is crucial as it helps mitigate the risk of failures that could occur at higher pressures, which may lead to leaks or ruptures.

The importance of maintaining this pressure limit stems from the material properties of polyethylene. At pressures above this threshold, the structural integrity of the piping may be compromised, resulting in safety hazards. Therefore, understanding and adhering to this pressure limitation ensures that gas transportation remains safe and reliable, protecting both individuals and properties from potential accidents associated with propane leakage or uncontrolled discharge.

This limit is outlined in relevant standards and regulations, emphasizing the need for both installers and users to remain vigilant about the specifications of the materials used in propane gas systems.
