   Difference Between Hot Bend and Cold Bend

Cold Bend

Hot Bend

All types of bending without heat

Type of Hot Induction bending for precise dimensions

Low cost

It will cost you high compared to cold bending

Bend to radically is not possible

It can be bent easily

Cold bending suitable fpr small bore

Hot bending is done for larger dia piping systems
