Stainless Steel Industrial Pipe Welding Die
Stainless steel industrial pipe welding dies are essential hardware components for manufacturing metal straight-seam welded pipes. Under the external force of the die, the steel coil is gradually cold-rolled and curled into shape within the die's arc, then welded to form a closed tube. Dies can be custom-designed per customer requirements—including round, oval, square, rectangular, or irregular shapes—and are widely used in various applications.
