ASTM A 671/672 Grade 70 Steel Pipe


Standard: ASTM A671/A672, ASME SA671/SA672

Size: 12.4mm to 1219mm(LSAW, SSAW, HSAW)

Wall Thickness: 3-12mm

Range of Length: 5.8m to 11.8m, 6m to 12m.

Ends procession: Plain, beveled, threaded

Both ASTM A671 and A672 are the standard Specification used for EFW (Electric-Fusion Welded) Carbon Steel Pipe used for atmospheric and lower temperatures applications and high-pressure service at moderate temperatures, which differ only in the testing requirements. ASTM A671/A672 grade 70 is a type of plain carbon, killed, fine grain steel pipe manufactured by ASTM A516 grade 70 steel plate. ASTM A671 CC70 and ASTM A672 C70 Pipes are fabricated from pressure vessel quality plate of numerous analysis and strength levels and appropriate for high-pressure service at an atmospheric and lower temp.
