Thick-walled stainless steel roll forming method

Roll forming method using thick-walled stainless steel tube rolling machine for rolling sheet metal is also available a variety of thick-walled stainless steel tube, steel pipe manufacturing process of this method is very simple, it does not require any special tooling to properly adjust the three-roll only between 678 distance, and if the diameter required for bending forming insufficient material utilization of this method to implement a high heat, but the drawback is that not only production but production of seamless steel tube joints. This gap welding to sew through follow-up, modern welding technology for welding cracks grow continuously improved, but performance is difficult to ensure the welds are consistent with the bulk properties, as well as the quality of welds, because the risk of the pipeline to withstand high-pressure fluid section a vertical cross-section, rolled steel welds and exactly vertical, so the pipe to withstand high temperature and pressure generally do not roll steel.

Thick-walled stainless piling pipe to the inventory of the market has been gradually advancing, the current gradually increased upside risks to price, do not rule out the recent correction may Steel City again, thick-walled seamless steel pipe stock price is lower than the strong spot market prices will steel will be forced to walk up. Thick-walled seamless steel pipe production capacity of the market growth is slow, once the market recovery and prosperity, few big steel mills surrounded them, China's steel industry will create a positive external environment. Adjustment disorder at home and could not ex-steel city, large enterprises are also actively involved in steel production, to reduce the homogenization of competition. Thick-walled seamless steel pipe production country backward steel production capacity of the case has not been much progress, mainly iron and steel enterprises are still operating at full capacity production. Thick-walled seamless steel prices at home and by consumer demand season, the impact of steel, at any time may be bottoming out, or even thick-walled seamless steel pipe sales rebounded strongly.
