Oiled marking:

    - Steel after passing wrer oiled to prevent corrosion,and according to user requirements for making.

Leveling Milling:

    - The flat steel anvil machine so that the origal curl,and then thouth the edge milling machine for two-sided steel milling,so as to meet the requirements of the plate width,plate edge parallelism and groove shape.

Shear molding:

    - The steel plate production line along the outer edge of the spiral curl into a tube.

Butt cut:

    - Double-sided submerged arc welding using advanced technology to pre-welding,internal welding,outside wilding.The welded steel pipe using a plasma-foot cut to specification length.
