Our company produces a series of pipe bending machine according to the pipe diameter supporting a variety of models for your reference.Pipe bender is composed of steel frame, lower die, upper die, fixture, hydraulic system and inner tube, etc.
Its working principle is to determine the reasonable fulcrum and stress point and apply bending torque to make the steel tube plastic deformation,By replacing the die kit and the corresponding inner tube, the cold bending operation can be carried out on various large diameter steel pipes within the suitable range.

1. Operators control the operation of all devices through the hydraulic system, easy to operate.
2. The whole machine adopts Cummins and other brands three-stage emission diesel engine and power pack, and optional low temperature preheating system.
3. The hydraulic system adopts international brand components such as Rexroth, and adopts unique preheating and cooling system, which improves the working efficiency and prolonging the life of the equipment.
4. Only by replacing the bending die kit and the corresponding inner tube, the pipe bending operation of various sizes within the scope of the bending machine can be carried out. The replacement is simple and convenient, saving manpower and material resources.
5. The structure of the machine is simple and reasonable, easy to maintain, the steel frame made of high strength steel has high strength, long service life, and excellent low temperature resistance.
6. Traction crawler walking device (optional) is suitable for field work, and wheeled walking device can be installed according to the actual working environment requirements.
Inner tube characteristics
1. The inclined block inner tube is suitable for the production of 16 "~60" curved pipe. It realizes the function of stretching through the relative motion of the inclined block and provides constraints for the pipe wall.
2. At the same time, the inner tube can move flexibly in the steel tube through its self-walking function.
