    Electric Resistance Welded Tube (ERW) - Leading UK steel

    The maximum concave or convex deflection of a flat side of a square or rectangular section of tube shall not exceed 0.5% of the nominal length of that side. Weld Height. The maximum height of the internal weld shall not exceed 60% of the specified thickness. Straightness. Tubes shall not depart from straightness by more than 1.5 in 1000. Hollow Section, Square Tube, Rectangular TubeS275J0H, S275J2H, S355J0H, S355J2H Rectangular/ Square hollow section manufacturing process Rectangular/ Square hollow section are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Home Welded Tubes, Inc.High frequency electric resistance welding (ERW) is a high productivity process yielding a stronger weld than standard TIG and laser welds, actually stronger than the parent material. We produce our tight tolerance tubing in a wide range of OD and wall thickness dimensions, in a variety of shapes - including round, square and rectangular, and

    Introduction to Welded Pipe Manufacturing - The Process

    • Electric Resistance Welding (ERW) ProcessSubmerged Arc Welding (Saw) ProcessElectric Flash Welding ProcessLap Welding ProcessHOLLOW STRUCTURAL SECTIONS - Steel Tube Form-Square Weld-Square (ERW) Process In the weld mill, driven forming dies progressively shape the at strip (1) by forming the top two corners (2) of the square or rectangular tube in the initial forming station. Subsequent stations form the bottom two corners (3) of the shape. Seamless Square Pipe BS 5950 Cold Drawn Rectangular Rectangular Size :10mm*15mm ----- 150mm*50mm ---- 300mm*400mm ---- 600*550mm.
