Electrical Induction PWHT Machine Weld Preheat Stress Relieving
Introduction of Air cooled post weld heatingtreatment machine:
Intermediate frequency induction heat treatment of weld seam refers
to the process of heat treatment of weld joints using intermediate
frequency heating power sources. The whole system consists of
intermediate frequency heating power supply, high temperature
electromagnetic wire, temperature detection and control system. The
intermediate frequency heat treatment power supply can process 50hz
alternating current and output an intermediate frequency current of
3-5khz. The intermediate frequency current generates a magnetic
field through the electromagnetic wire, and the pipe wrapped by the
electromagnetic wire will generate an induced current and generate
heat. The temperature control unit can detect the temperature of
the pipe wall and transmit the temperature information to the
control system in real time to form a closed loop of temperature
control, and the control system is responsible for heating the
equipment according to the preset temperature curve.
