ERW Black Pipe Production Line High-Frequency Straight Seam Welded Pipe ERW Tube Mill
Product Introduction
The round tube unit without roller change is a new product developed by our company, when changing the product specifications, breakdown section of the forming machine do not need to change the rolls,so that it can save a lot of investment in rolls, especially suitable for large and medium-sized units.
Process Flow
Steel Coil → Double-arm Uncoiler → Shear and End Cutting & Welding → Coil Accumulator → Forming (Flattening Unit + Main Driving Unit + Forming Unit + Guide Unit + High-Frequency Induction Welding Unit + Squeeze Roller) → Deburring → Water Cooling → Sizing & Straightening → Flying Saw Cutting → Pipe Conveyor → Packaging → Warehouse Storage
Technology
ZTZG was established in 2000, with 20 years of design and manufacturing experience. We are:
We have the honor to get 10 plus letters patent, China Cold-Formed Steel Technology and Equipment Innovation Award, and numerous other honors.
Theory
The straight seam welded pipe production line uses roll forming theory to gradually shape the strip steel into a billet tube, then through Kelvin effect and proximity effect of the high frequency current to heat up the welding line, letting it reach the welding temperature and finish the welding. A scraping device will then cut off the extra burr created during the welding phase, and the heated tube will go through the process of water cooling which lowers the tube temperature to standard degrees. Next, another round of roller-sizing will further shape the tube size and thickness and let it reach the desired diameter or dimension. Lastly, the tube will go through a rough straightening process through Turkshead and finally come out as the finished product.
