ASTM A53 GR.B ERW Welded Steel Pipe
gnee pipe team
ASTM A53 GrB welded steel pipe is made of high-quality steel billet through hot rolling, cold drawing and other processes. The chemical composition and mechanical properties of this steel pipe comply with the requirements of American standard ASTM A53/A53M. ASTM A53GrB ERW steel pipe has high strength, good toughness, and good processing and welding properties.
Grade B A53 Welded Pipe is available in a wide range of outside diameters and wall thicknesses. Depending on the application field, the outer diameter of ASTM A53GrB steel pipe usually ranges from 6mm to 426mm, and the wall thickness ranges from 2mm to 25mm. The length of this steel pipe can be customized according to customer needs, with a maximum length of 12 meters.
Because A53B ERW Pipe has excellent material properties and good processing performance, it is widely used in petroleum, chemical industry, electric power, machinery manufacturing and other fields. For example, in the petrochemical industry, ASTM A53 B ERW Steel Pipe can be used to transport high-temperature and high-pressure oil, natural gas and other media; in the power industry, this steel pipe can be used to manufacture boilers, heat exchangers, etc.

ASTM A53 Grade B ERW Steel Pipe

Expand information:
ASTM A53 pipe comes in three types (F, E, S) and two grades (A, B).
ASTM A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)
ASTM A53 Type E has an electric resistance weld (Grades A and B)
ERW Pipe Manufacturering Process:
Straight seam high frequency welded pipe (ERW) is formed by forming a hot-rolled coil through a forming machine. The skin effect and proximity effect of high-frequency current are used to heat and melt the edge of the pipe blank.
