Size specification of large diameter electric welded steel pipe

API SPEC 5L-2007 (line pipe specification), compiled and issued by the American Petroleum Institute, is commonly used all over the world，Line pipe standard:API SPEC 5L-American Petroleum Institute Standard； GB/T9711-China National Standard。

ASTM A213 T22 is the part of ASTM A213 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, Heat-Exchanger Tubes.

ERW - Electric Resistance Welded For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly.

Seamless Ferritic Alloy Steel Pipes for High Temperature Use

ASTM A53 es una aleación de acero al carbono que puede utilizarse como acero estructural o para tuberías de baja presión. La tubería de acero al carbono ASTM A53 (ASME SA53) es una especificación que cubre la tubería de acero sin soldadura, soldada en negro y galvanizada en caliente de NPS 1/8 "a NPS 26. A53 es adecuado para aplicaciones mecánicas y de presión, así como para uso general en líneas de vapor, agua, gas y aire.
