ASTM A860 is a standard specification for high-strength ferritic steel materials, mainly for butt welding fittings.It connects pipes together through welding and is suitable for high-temperature and high-pressure working environments.It is mainly used in petroleum and natural gas pipeline systems. W

ASTM A403 pipe fittings are made from austenitic stainless steel.ASTM A403 pipe fittings are widely used in various fields and industries for pipeline systems.

ASTM A234 butt welding pipe fittings are an important type of pipe connection fitting that uses welding to connect pipes together, The grades are ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 and WP22.

Butt welding fittings are an important component of pipeline systems. Whether the dimension of welded pipe fittings meets the standard requirements is an important indicator for inspecting the quality of butt welding fittings.

Common types of butt welding pipe fittings include 90 degree elbow, 45 degree elbow, tee, crosse, cap, concentric reducer, eccentric reducer, stub end, etc. The ASME B16.9 standard defines the size ranges for various types of butt welding pipe fittings.
