What characterizes medium pressure natural gas?

Medium pressure natural gas is characterized by a pressure range that exceeds 14 inches of water column (W.C.) but does not exceed 5 pounds per square inch gauge (PSIG). This classification is important because it helps in determining the appropriate design, materials, and safety measures required for gas distribution systems.

The pressure range defined by this classification allows for the efficient transport of natural gas while ensuring that it remains within safe operating limits, reducing the risk of leaks or other hazards associated with higher pressure systems. Understanding this distinction is crucial for compliance with regulatory standards and for the proper functioning of gas installations in various settings.

Other pressure classifications are based either on lower figures, which do not meet the medium pressure criteria, or higher pressures that move the classification into high-pressure categories, impacting installation practices and safety regulations differently.
