Optimization of Pipe Induction Bending Process Parameters
ASME 2017 India Oil and Gas Pipeline Conference, 2017Hot pushed induction heating is a bending process used to bend pipes having a small bending radius with a large diameter. This is a complex process since it involves mechanical process of bending and thermal process of localized induction heating. This paper deals with the optimization of induction bending process parameters such as bending speed ...

Theory of pipe-bending to a small bend radius using induction heating
Journal of Materials Processing Technology, 1990Abstract A theory for the bending of inductively heated pipes to a small bend radius is presented. Stress-and strain-states under various loading conditions and for different bend radii are calculated and simulated numerically by the 3-D thermal elasto-plastic and the rigid-viscoplastic finite-element methods.

The International Journal of Advanced Manufacturing Technology, 2015
The constitutive equation of P11 alloy was built to describe the hardening curve obtained from the compression tests. Then, the local-induction-heating bending process of bend pipe with straight section was simulated by using the finite element method. The forming experiments were also performed based on the simulation results.

Finite element residual stress analysis of induction heating bended ferritic steel piping
AIP Conference Proceedings, 2014Recently, there is a trend to apply the piping bended by induction heating process to nuclear power plants. Residual stress can be generated due to thermo-mechanical mechanism during the induction heating bending process. It is well-known that the residual stress has important effect on crack initiation and growth.
