Cr12MoV Steel Pipe Machine Mould roll Forming Roller Vacuum Heat Treatment

Cr12MoV Steel Pipe Machine Mould D2 Tube Mill Die ERW Duct Roller Spacers

Product Description

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

The welded pipe mold is widely used in the production of decorative pipes, industrial pipes, ERW welded pipes and other pipes.

Product Process

Raw material - sawing material - rough processing - drilling - fine finishing - roller polishing - typing Code - semi-finished product inspection - heat treatment - grinding hole - horizontal die cutting keyway - quality inspection - oil cleaning - packaging
