A pipe bending machine is a specialized forming equipment. By applying controllable bending force to metal pipes, it causes permanent deformation of the workpiece, thereby obtaining the required bending angle, bending radius, bending shape, and bending direction to meet the needs of various industries.
Pipe bending machines are mainly divided into cold bending machines and hot bending machines, also known in the industry as medium-frequency bending machines, based on the bending process. The working principle of a medium-frequency bending machine is to heat the steel pipe to a plastic state of 900℃-1100℃ through medium-frequency induction heating before bending. In summary, it involves heating, pushing, bending, and cooling simultaneously to achieve the final bending effect. It is typically suitable for processing large-diameter, thick-walled pipes, with a diameter range up to 1420mm. It is suitable for the following industries:
- Energy and Power Industry:Primarily used for processing boilers and main steam pipelines in thermal and nuclear power plants; long-distance oil and natural gas pipelines.
- Heavy Industry and Infrastructure Industry:Primarily used for processing process pipelines in chemical plants; marine fuel oil and hydraulic pipelines; large-scale building steel structures; subway tunnel supports.
- High-End Manufacturing Industry:Primarily used for processing metallurgical production lines; hydraulic channels for heavy machinery; special pipelines for aerospace vehicles.
- Special and Civil Applications: Primarily used for processing important industrial circuit pipelines; cleanroom pipelines in pharmaceutical workshops; curved beams and columns in large venues.
