ASTM A420 WPL6 Low Temp. Fittings

ASTM A420 is the standard specification for pipe fittings of carbon steel and alloy steel used for low temperature services. WPL6 is the most used grade material under A420. 

Besides Grade WPL6, the standard also includes WPL9, WPL3, WPL8, impact test temperature correspondingly at -45℃, -75℃, -100℃, -195℃.

ASTM A420 covers elbow, tee, reducer, cap, union and etc, which manufactured according to ASME B16.9, ASME B16.11, MSS SP-79 and MSS SP-95, types in seamless and welded structual pipe fittings. These fittings commonly used in pressure pipelines and pressure vessel/tanks at lower temperature.

ASTM A420 WPL6 pipe fittings compatible with ASTM A333 Grade 6 Pipe and ASTM A350 LF2 Class 1 Flange.
