Which type of piping is permitted for use when working with LP-Gas?

Wrought iron pipe is considered a suitable choice for use with LP-Gas due to its physical properties and resistance to corrosion. It is durable and can withstand the pressures associated with the gas, providing a reliable conduit for propane. The use of wrought iron also minimizes the risk of leaks, which is paramount for safety in gas handling and installation.

Other materials mentioned, while common in various applications, do not meet the specific safety requirements for propane gas systems. PVC pipe, for instance, is not designed to handle the pressures and thermal properties of gas applications, making it unsuitable and unsafe. Galvanized pipe may be used in some contexts, but its susceptibility to corrosion can pose risks in long-term installations. Additionally, plastic tubing is generally not approved for LP-Gas use due to concerns about durability and the potential for leaks under pressure. Therefore, wrought iron pipe emerges as the preferred and safe option in the context of LP-Gas piping.
