9Cr2Mo Material Pipe Making Equipment Molds Steel Duct Mill Rolling Dies Tube Roller Spacers
Product Profile
Welded pipe mould tube roller die is a necessary hardware accessory for manufacturing metal straight seam welded pipe. Under the action of the external force of the welded pipe mould, the steel coil is gradually forced to be cold rolled and curled in the arc of the tube roller, and then welded to obtain the closed welded pipe.
Usage
Welded pipe molds are used to produce stainless steel profiles, copper, aluminum, and iron profiles, as well as high-frequency welded pipes. The quality of the roll determines the quality of the product.
