U-tube bending (duplex steel)

For cold bending, the elongation rate can be calculated to control the thinning rate. The hot bending temperature is difficult to control.

A manual pipe bender is used.

Bending of U-tubes (duplex steel): As for the specific material, it is presumed to be S32750. Duplex steel presents certain difficulties in terms of cold bending due to its high hardness, but this also depends on the dimensions of the tube as well as the minimum bending radius. What is the method of bending? Cold bending: Quality risks of bending? It depends on the size of your tubing and the minimum bending radius; you can try bending it first. We have previously supplied U-shaped tubes made of S32750 and S32760 to customers in the United States and Australia, and the process isn’t too difficult. However, it is still challenging to control the rate of thinning and the degree of ellipticity. What about the bending process? The tube is filled with an inert gas for protection. Inspection of bends? Dimension inspection of curved parts, surface quality inspection, hydraulic compaction test, penetration test, etc
