Product Description

ASTM A671 Gr. Cc65 Cl12 Carbon Steel Welded Pipe 

A671 CC65 CL12 specification covers standard requirements for electric-fusion-welded steel pipe with filler metal added, for atmospheric and lower temperatures. The steel pipe shall be fabricated from a pressure vessel quality plate of several analysis and strength levels. Several grades and classes of pipe shall be provided. Grade shall designate the type of plate used while class shall designate the type of heat treatment performed during pipe manufacture. 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.
