ASTM A500 Grade B Electric Welding Pipe

ASTM A500 Class B ERW Electric Welded Pipe Product Introduction

ASTM A500 Class B electric welded pipe is manufactured using high-frequency resistance welding technology and is specifically designed for structural applications. This product has a yield strength of ≥290MPa and a tensile strength of ≥400MPa. Precision cold bending ensures dimensional accuracy, and the weld seam, after heat treatment, maintains performance consistent with the base material. It is suitable for load-bearing applications such as building frames and supporting structures, and offers complete third-party certification and quality traceability services.

All tubing shall be free from defects and shall have a workmanlike finish.Surface imperfections shall be classed as defects when their depth reduces the remaining wall thickness to less than 90 % of the specified wall thickness.Defects up to 33% of the specified wall thickness in depth may be completely eliminated by cutting or grinding to complete metal.If filler welding is used, the wet welding process shall be used and the protruding weld metal shall be removed to maintain a smooth surface.Surface defects, such as handling marks, minor mold or roll marks, or shallow pits, are not considered defects provided they can be removed within the specified wall thickness.
