SKD11-D2-Cr12MoV Welded Tube Die
Welded pipe molds are essential hardware components for manufacturing metal straight-seam welded pipes. Under the external force of the mold, steel coils undergo progressive cold rolling and curvature within the mold's arc to form the shape, followed by welding to create a closed tube. Molds can be custom-designed per customer requirements—including round, oval, square, rectangular, or other special shapes—and are widely used in decorative tubing and industrial applications.

Welded pipe molds are essential hardware components for manufacturing metal straight-seam welded pipes.A steel coil is gradually cold-rolled and curved into shape within the mold's arc under external force, then welded to form a closed welded pipe.Molds can be customized to meet customer requirements, including circular, oval, square, rectangular, and special shapes. Welded tube molds are widely used in the production of decorative tubes, industrial tubes, ERW welded tubes, and other types of tubing.
