Comparison of Pipe Cold-rolling Hot Rolling for Seamless Pipes

Pipeline insulation in the hot-rolled and cold-rolled cold-rolled steel two types. Hot-rolled general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, geological steel pipe and other steel pipe; cold Rolling general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, other steel pipe, including carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel thin wall steel pipe, special-shaped steel pipe .

Pipe insulation in the production may use equipment: steel shot blasting machine, three PE winding equipment, PE pipe black and yellow jacket extubation machine, sand blasting equipment, polyurethane low pressure generator, foaming platform, glass steel Winding machine, two PE coating, cement mortar spraying machine and other anti-corrosion insulation matching testing equipment.

Pipe insulation In the external force of the anti-corrosion steel pipe deformation, stability, anti-fatigue and other aspects may have an adverse effect on the performance. When processing hot-rolled steel products, the thickness and width of the pipes are not well controlled. Since the beginning of thermal expansion and contraction, even if the length and thickness of hot rolling are up to standard, a certain negative difference will occur after cooling. The wider the width of the negative edge, the thicker the thickness will be.
