The unit is used for material storage preparation for the high-frequency welding straight seam cold bending host.

The unit is used for material storage preparation for the high-frequency welding straight seam cold bending host. The strip steel is uncoiled, leveled, After butt welding at the plate ends, it enters the horizontal spiral looper for storage of materials for the main machine, plate heads, and plate ends. This unit is mainly used for the production of straight seam welded pipes and other products in industries such as metallurgy, construction, transportation, machinery, and vehicles. The unit adopts PLC control, compact layout, advanced technology, high degree of automation, and simple and convenient operation and maintenance.


Our technical personnel have successfully completed the installation and debugging work in the entry section of the unit and it has been put into operation smoothly!
