Hot 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, water flow rate, water pressure, air pressure and induction coil to water coil distance. Mother pipes of size 464 mm OD × 20.60 mm and grade API 5L X65MS/MO were used to make trial bends of 5D radius in 30° angle. Trial bends were subjected to mechanical tests and microstructural analysis to evaluate the effects of selected process parameters.
