Stainless Steel Welded Pipe Molds
Stainless steel welding tube dies are essential hardware components for manufacturing metal straight-seam welded tubes. Under the external force of the die, a steel coil is progressively cold-rolled and curved into shape within the die's arc, then welded to form a closed tube. Dies can be customized per client requirements—including round, oval, square, rectangular, or special shapes—and are widely used in decorative tubing applications.
