Cold Bending Method.
As the name suggests such a bending technique involves certainly no consumption of heat for the pipes to bend. The cold bending technique completely depends upon mechanical force. As there is no heat involved physical force is applied to the pipes to shape them in a different configuration.
Hot Bending Method.
The hot bending technique includes heating the pipe at a certain temperature to make precise and swift bends. Hot bending can also be referred to as induction bending.
