Welded Tube making machine

High-frequency ERW straight seam pipe making machine,which called Welded Tube making machine,for the whole prodcution line, at first, the coil is loaded at the uncoiler, then but-welding the ends of coil, delivering to accumulator. After accumulator, the strip is pulled from accumulator contiousely by fixed speed, is formed to opened-pipe at forming machine, then welded by High frequency welder, de-burred, cooled, shaped and sized as round pipe and rectangluar&square pipe at the sizing area. Then the sized pipe is straightened after Turkey-head device and then cutted to fixed length by flying saw. At last, the fixed pipe is delivered from run-out table and inspected at the table.
This line could produce the round pipe, the rectangular and square pipe by material of cold/hot-rolled coil etc. It could be used at the metallurgy, construction, transportation, machinery, automobile industry. Adopting "W" forming type, it could make much more reasonbale force, and much more perfect forming shape at each stand etc.

Process of the Production Line
Raw material (strip steel roll) - Material feeding - End cutting and butt welding (hand welding) - Strip storage cage - Material feeding and forming - High frequency welding - Removing outer burr - Cooling water jacket - Fix the diameter and straightening - Cut off with flying saw - Material unloading (Manually stow and bind up) - Inspection - Storehouse
