What is the maximum allowable pressure for threaded fittings for a 2" diameter?

The maximum allowable pressure for threaded fittings is determined by various factors including the material of the fitting, the diameter, and the temperature at which it is operating. For a 2" diameter threaded fitting, the allowable pressure is commonly standardized in industry practices and codes, which typically consider these specific dimensions and conditions.

In this case, the choice of 600 psi aligns with common standards established by piping codes, particularly when dealing with standard pressure ratings for threaded steel or other related materials. These standards ensure that the fittings can safely handle the pressures expected in typical applications without risking failure.

Additionally, while threaded connections are widely used and have adequate strength, they are also subject to certain limitations, including the potential for leakage or failure under excessive pressure. Operating within the prescribed limits, such as the 600 psi standard for 2" diameter fittings, ensures safety and reliability in high-pressure piping systems.
