Socket weld forged steel fittings are available in which pressure designations?

The pressure designations for socket weld forged steel fittings are critical for ensuring that the components can withstand the operational pressures expected in various applications. The correct choice includes the values of 3000, 6000, and 9000 psi, which align with the standards set by organizations such as the American Society of Mechanical Engineers (ASME).

These designations suggest the maximum allowable working pressure at a standard temperature, indicating that fittings categorized under these values are designed to safely handle pressures up to and including those figures. This knowledge is essential for steamfitters and other professionals when selecting the proper fittings for high-pressure systems, ensuring both safety and performance.

The other options present pressure values that do not conform to standard classifications for socket weld forged steel fittings, making them unsuitable for this context. Understanding these specific designations is vital for compliance with industry standards, proper installation, and the overall integrity of piping systems.
