ASTM A 671 covers standard requirements for electric-fusion-welded (EFW) Steel pipe with filler metal added, for atmospheric and lower temperatures. This Pipe are Fabricated from Pressure Vessel Plate of Several Analysis and Strength Level. This Pipe are Suitable for Low Temperature Service. Grade shall designate the type of plate used while class shall designate the type of heat treatment performed during pipe stockist . Class shall be designated as to whether the weld is radiographically examined, and as to whether the pipe is pressure tested. Steel samples shall undergo tension and transverse guided weld bend tests and conform to the specified mechanical requirements.
