Comparison of hot rolling hot rolling of seamless steel tube pipe.
May 10, 2018

Comparison of hot rolling hot rolling of seamless steel tube pipe.

Pipe insulation hot rolling and cold rolling seamless steel tube in two categories. Hot points in the general steel tube, low and medium pressure boiler pipe, high pressure boiler tube, alloy steel, stainless steel pipe, oil cracking pipe, geological steel pipe and other steel pipe, etc.; Cold rolled steel pipe generally, low medium pressure boiler pipe, high pressure boiler tube, alloy steel, stainless steel pipe, oil cracking pipe, steel pipe, other also includes carbon thin wall steel tube, alloy thin wall steel pipes, thin-walled stainless steel tube, steel tube.

Pipe insulation may use the equipment in production: steel pipe shot blasting derusting machine, 3 PE, PE pipe winding equipment black yellow jacket drawbench, sandblasting derusting equipment, polyurethane low pressure machine, foam platform, FRP winding machine, two PE coating, anticorrosion heat preservation facilities, such as cement mortar spraying machine testing equipment.

The deformation, stability and fatigue resistance of pipe insulation under external force can have a negative effect on performance. When processing hot rolled steel products, the thickness and side width of the pipe are not well controlled. Due to the heat bilges cold shrink at the start of the hot rolled out even the length, thickness, standard, finally still can appear some negative difference after cooling, the negative difference edge width is wider, the thicker the thickness will be more obvious.
