6D anticorrosive bend

6 d anticorrosive bend pipe bending, first remove floating rust and dirt on the surface of the steel tube bending, will bend the pipe with the specifications of the pipe clamp is installed on the derrick, and adjust the chuck centerline to the required position, bending radius to be fixed; Then, adjust the position of the supporting roller, so that the distance from the center of the bent tube to the center of the axis is equal to the bending radius. Adjust the height of the supporting roller and bracket, make the center of the bending pipe in the same plane with the center of the clamping center, and parallel to the rotating arm plane; Put the steel pipe into the heating ring and clamp it in the clip. Adjust the heating coil to align the inner surface of the steel tube. Open a medium frequency heated crew, when the pipe is heated to 950-1000 ℃ (in orange), immediately start the motor to bend; Open the cooling water valve at the same time, water spray cooling on the local part
