Square & Rectangle pipe mill is the special equipment to produce square and rectangle Steel pipe. this equipment adopts the multipoint bending combined-type forming Technology. One set of mould can produce all size of square and rectangle pipe. Compared with the traditional technology, the produce will have a good Appearance, a good angle; share one set of mould, can cut down the cost of the Machine, shorten the time of adjusting the mould; decrease the forming Resistance, lighten the mould wear, reduce the load of power utilization.

 

Process Flow

Raw Material (Strip Coil) → Decoiler → Snubber Roller + Pinch Roll + Leveler → Shear & Butt Welder → Horizontal Accumulator → Forming (directly forming to square to Rectangle shape) → HF Welding → Scraping → Cooling → Sizing → Straightening → Cutting → Run-out
