Cold bending technology of carbon steel pipe
Cold bending is a mechanical process that reshapes carbon steel pipes at room temperature using external force, without heating. This process enables the pipe to form specific curves or angles required in construction, machinery, and piping systems. Commonly used tools include pipe bending machines, roll benders, and hydraulic presses. Cold bending is widely applied in the processing of seamless steel pipes, especially when high dimensional accuracy and surface integrity are required.
