What is the Minimum Allowable Working Pressure (MAWP) for a tank of propane?

The Minimum Allowable Working Pressure (MAWP) for a tank of propane is typically set at 250 PSIG. This value is derived from safety standards and regulations designed to ensure that the tanks can safely handle pressures encountered in various operational circumstances without risk of failure. Propane is stored under pressure, and thus the design of the tanks must account for the potential maximum pressures that could be encountered during filling, thermal expansion, or other scenarios.

The MAWP helps establish baseline safety criteria for the operation and maintenance of propane tanks, ensuring they can withstand more than the normal operating pressures during their service life. It's vital for technicians and operators to adhere to these standards to prevent accidents, leaks, or catastrophic failures that could arise from the incorrect handling of pressurized fuels like propane. Proper understanding of these figures helps maintain compliance with regulations and enhances general safety practices in the industry.
