Induction heating benefits


Compared to conventional preheating and stress relieving methods, induction heating offers numerous advantages, including improved heat uniformity and quality, reduced cycle time, and lower consumables costs. Induction heating is also safe, reliable and easy to use, and scores higher than alternative technologies in power efficiency and versatility.



1. Air cooling: Convenience to install.

2. Temperature recorder: Recording the whole heating curve and print it

3. Soft induction coil: Easy to wind on different working piece.

4. Temperature Controller: Keep the heating process same with PWHT requirement .

5. PLC touching screen: Intuitive to see and easy to operate.

6. Induction heating power: High heating speed and heating efficiency, electrical energy Saving

7. Quickly heating speed. Can reach 850 degree C within 1 hourSave heating times

8.Electrical Power Saving: Can save more than 50% electrical power compare compared to conventional preheating and stress relieving methods


Applications and main using fields: 

MYD series induction heating system are air-cooling induction heating equipment with DSP system. Their main applications are pipeline heating, pre-heating of welding, post-welding heat treatment, stress relief, annealing,ect. 


Coating heating, Shrink fitting

Weld preheating, Postweld Heating Treatment, Stress relieving



The industries involved are petrochemical, oil and gas pipelines, aerospace, shipbuilding, steel, boilers, pressure vessels, cylinders, metal structure, spatial structure, railway bridges, electricity water, mine construction, vehicle manufacturing, nuclear power, mining, plastics processing.
