Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. Stainless steel pipe is a kind of economical cross-section steel. It is an important product in the steel industry. It usually accounts for about 8%-16% of the total steel. It has a wide range of applications in the national economy and is itself a saving The economic section of metal steel is an important part of high-efficiency steel, especially in the oil drilling, smelting and transportation industries.

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.

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.
