Four major reasons for deformation in pipe processing of pipe bending machines

What is the reason for varying degrees of deformation during pipe bending machine processing? Below, the expert of the pipe bending machine will explain the four main reasons to everyone.

1. The large elongation deformation in the tensile deformation zone outside the neutral layer does not meet the plastic allowable value of the material and causes breakage;

2. Within the compression deformation zone on the inner side of the neutral layer, the thin-walled layout section subjected to tangential compressive stress will not become super unstable and wrinkled;

3. If there is a requirement for ellipticity in the pipe fittings of the pipe bending machine, control the deformation of the cross-section to occur;

4. If the pipe fittings have strength requirements to withstand internal pressure, control the forming limit of wall thickness reduction.
