Common Bending Forms of Mild Steel Tubes

‌Mild steel pipe is a type of carbon steel pipe. ‌Mild steel pipe has a carbon content of less than 0.25%. It is also called soft steel because of its low strength, low hardness and softness. Common bending forms of mild steel tube mainly include four types: pressing, rolling, return bending and extrusion bending. These methods have their own characteristics and are suitable for different bending requirements and material properties.

Pipe Pressing

 This bending method does not require special molds and can be completed on a press. The pipe pressing method is simple and suitable for situations where the curvature radius does not need to be precisely controlled.


Rolling

On a plate rolling machine or a steel bending machine, a grooved roller is used for bending to obtain a bending effect with uniform curvature. Rolling is suitable for occasions where a larger radius bending is required or where precise curvature requirements are required.


Return Bending

It includes rolling return bending and drawing return bending. The former is bent on a vertical or horizontal pipe bending machine, and the latter is also bent on a vertical or horizontal pipe bending machine, but the clamping should be tighter to generate longitudinal tension. Return bending is suitable for bending requirements that require a larger curvature change or a specific shape.


Extrusion Bending

including mold extrusion bending and mandrel extrusion bending. The former has a regular cross-sectional shape of the tube and is generally cold extruded; the latter is generally hot extruded and is suitable for bending that requires higher precision and specific shapes.


The choice of these methods depends on the specific engineering requirements, including factors such as bending radius, material type, and whether precise control of curvature is required. In actual applications, different bending methods may be used according to specific circumstances, or several methods may be combined to achieve the best bending effect.
