The elbow is made by this process

Elbow forming machine in bend processing used in the production process, the design process of the composite wear-resistant elbow is stay in steel pipe bending part of the set of induction coil, 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 and bending of making steel pipe section with coolant cooling rapidly, while heating, propulsion, bending, while cooling, bending the elbow out constantly.
