Application Areas: Boiler Tubes, Heat Exchanger Tubes, Heater and Superheater Pipes

Cold bending is a type of bending method that makes the bending by mechanical force and without additional heating source. In this method, pipe or profile is bended at machine in required radius and degree.



Advantages and Disadvantages of cold bending comparing with hot bending:

-After cold bending process there is no need to wait for cooling of pipe and that makes cold bending quicker comparing with hot bending.

-Cold bending is less expensive due to its machines are cheaper.

-After bending process cold bending has cleaner surface comparing with hot bend.

-Cold bending method has limited technical range on outside diameter/wall thickness and bending radius.

-After cold bending process mechanical strengths can be increased but in the same time hardness values can increase above to acceptable values.



In summary up to 6” outside diameter and 7D bending radius, cold bending has lots of advantages comparing with hot bending method in various alloy grades.
