Roasted bend pipe is mainly used for building circular steel structure, tunnel support, the roof beam bending, the subway engineering, aluminum doors and Windows, ceiling, cylindrical inner frame, balcony railings, shower door, production lines, rail, fitness equipment and other industries。
Process: roasted bend is straight after cutting through the push pipe bending machine, induction coil, stay in steel pipe bending part on mechanically pivoted arm stuck pipe head, zhongtong into the intermediate frequency induction coil current heating tube, when the steel tube temperature to the plastic state, after the steel pipe end with mechanical thrust forward, bending, bending make steel tube parts with coolant cooling rapidly, this heating, while advancing, bending, while cooling, constantly to bend pipe bending.
The process of a hot bending pipe:
The heat - bending bend is the more primitive method of making the pipe after the pipe is filled with sand, then the pipe is heated to simmer the big bend method. This method has great flexibility, but not high efficiency, high energy waste and high cost. At present, steels of carbon steel are less used in this method, but there are obvious advantages in the bending of some non-ferrous metal pipes and plastic pipes. The process of this method is mainly: pouring sand, heating, bending and clearing sand.
