ASTM A860 WPHY 65 is a high-strength carbon steel pipe fitting grade designed for use in high-pressure and high-performance pipeline systems. The ASTM A860 specification covers wrought high-strength ferritic steel butt-welding fittings intended for pipelines and pressure piping applications where superior mechanical strength and reliability are required.
The designation WPHY stands for Wrought Pipe High Yield, indicating that the fittings are engineered to provide a minimum yield strength of 65,000 psi (450 MPa). This high yield strength allows the fittings to withstand heavy loads, high pressure, and demanding operating conditions commonly found in long-distance pipelines and industrial piping systems.
