Our offered A358 welded pipe Specification covers Electric-Fusion-Welded Austenitic Chromium-Nickel Alloy Steel Pipe for High-Temperature Service, designated Grades TP304L, TP304, TP316 and TP316L etc.

EN19 Alloy Steel Seamless Pipe is an alloy steel seamless pipe made of EN19 (also known as 42CrMo4 or 1.7225).

ASTM A822 is a standard specification for seamless cold-drawn carbon steel pipes, which are mainly used in hydraulic systems and other similar applications, where the forming operation requires small radius bending and flaring.

Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond. The longitudinal ERW seam does not require filler metal.
