ASTM A671 / A671M - 16 (Standard Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures)
A671 specification covers standard requirements for electric-fusion-welded steel pipe with filler metal added, for atmospheric and lower temperatures. The steel pipe shall be fabricanted 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.

S14. Description of Term
A671 covers EFW carbon/alloy steel pipe for atmospheric and lower temperatures, made from pressure-vessel quality plate with grade + class designations.
Class (e.g. 12, 22, 32) defines heat treatment and NDE/radiography packages — always quote class with grade.
A671 is typically for atmospheric/lower-temperature service; A672 for high-pressure / high-temperature service. Follow the datasheet.
CC60, CC65, CC70 are widely ordered; also CA/CB/CD series depending on plate grade.
We supply this product for domestic and export projects with MTC (EN 10204 3.1 standard; 3.2 / TPI on request). Include destination, Incoterms and inspection needs on the RFQ.
