All pipe fittings must be forged steel stamped with a pressure rating of at least what psi?

The requirement for all pipe fittings to be forged steel and stamped with a pressure rating of at least 6,000 psi ensures that these components can handle the high pressures typically associated with the transport and use of compressed natural gas (CNG). This pressure rating is significant for maintaining the integrity and safety of the piping systems, as CNG is stored and transported under high pressures, generally ranging from 3,000 to 4,500 psi.

Fittings that meet or exceed this pressure rating are designed to withstand the potential stresses and environmental factors that may affect their performance over time. This level of assurance helps prevent failures, leaks, and hazards that could arise from using substandard materials or improperly rated fittings.

Adhering to this standard is critical in ensuring the safety and efficiency of CNG systems, thereby protecting both the infrastructure and the personnel involved in handling CNG.
