22.5 45 90 120 180 degree API 5L GR.B/X42/X52/X65/X70 5D 3D carbon steel pipe fitting hot-bending bend BE

 The hot-bending bend is to put a sensing ring on the part of the steel pipe to be bent through the bend pusher after the straight pipe is cut, clamp the pipe head with a mechanical rotating arm, and apply medium frequency current to the sensing ring to heat the steel pipe. When the temperature of the steel pipe rises to the plastic state, push it with mechanical thrust at the rear end of the steel pipe for bending, and the bent steel pipe is quickly cooled with coolant, so that it can be heated, pushed While bending and cooling, bend the elbow continuously. Hot-bending bend is mainly used in many industries, such as Chemical industry, petroleum industry, shipbuilding industry,building arc steel structure, tunnel support, subway engineering,production line track and so on
