Analysis of the reasons for cracks during the production of small-diameter seamless steel tubes (cold-formed)
The main reasons for cracks in cold bending are: the first bending radius is too small； The second bending process should include preheating ； The third bending speed is too fast.
How to operate bending correctly? Does anyone have a method to suggest?
Steel pipe bending is a form of material deformation processing. First, the selection of material is crucial; materials with good plasticity and ease of processing can be bent using cold working methods, while those with lower plasticity can be shaped through hot working. If there are issues with the quality of the selected material, this will be reflected in the plastic processing process. Another factor is the bending technique itself – if the bending radius is greater than 3D, special molds are used for shaping. Additionally, methods such as filling the pipe with sand can be employed to improve the quality of the bend
