Processing of Spiral Welded Pipe

Prevent localized corrosion

Product Details

Processing and welding of spiral weld pipes: iron rust, oil, water and paint that does harm to welding shall be removed before welding. The same grade of steel welding rods shall be selected. Its spot welding time interval is shorter than that of carbon steel, so the spiral weld pipe brush shall be used when cleaning up welding slags. After welding, the surface shall be ground or cleaned up to prevent local corrosion or reduce the strength.
Cutting and punching: spiral weld pipes are stronger than ordinary materials, so higher pressure is required in punching and shearing, and the clearance between tools is accurate to prevent hardening of shearing and processing. Priority is given to plasma or laser cutting. When gas cutting or arc cutting is required, the heat affected zone shall be subject to heat treatment during grinding.
