Before starting the bending operations the hydraulic pressure / water level / flow switches etc. are checked. The pipe is now heated by induction to the temp of 815 - 995 C. By pushing the pipe by push clamp the bending of the pipe is started slowly and carried out at speed of 10 - 40 mm/min. The bending operation is stopped at the specified angle of bend and predetermined arc length.
