40kw air cooling induction heating machine for pipeline PWHT post weld heat treatment
Brief introduction of Canroon 40kw induction heating machine:
40kw induction heating machine is designed and manufactured by Canroon fused for pipes PWHT/post weld heat treatment (DHT dehydrogenation heat treatment, ISR intermediate stress relief), widely applied and welcomed by oil&gas piping, offshore platform construction, and power plant construction & repair.
For PWHT, the suitable pipe size with Diameter of 200-800mm and Thickness of 25-60mm, heating temperature will reach 788℃ at most.
Besides, application of welding preheat, joint anti-corrosion coating and shrink fitting are also very efficient.

Features of induction heating machine:
- Friendly Interface and Accurate Control
The control board offers various parameters for setting so the heating process can be controlled precisely by giving value to temperature, time, heating rate, cooling rate, etc.
The interface offers two basic control mode to choose including temperature control and power control. The former one has 4 modes of preheat, bake-out, PWHT, custom. The last one has 2 modes ofconstant power and power VS time. Each mode offers different parameters to set. Thus brings the benefit of wide applicability and precise control.
Fault codes will display and be recorded for reference, and system will respond with protection action like shutdown once fault occurs such as open-loop output or short out.
Due to modular design, the maintance will be easy and low-cost.
Once fault occurs, CR2000 will act with display of fault code, which was detailed explained in the manual book.
This uniquely energy-efficient process converts up to 90% of the expended energy into useful heat, and time-to-temperature is faster than conventional processes due to the method of applying heat, reducing cycle time.
The heat is induced within the part itself by alternating electrical current, thus uniform temperature throughout the heating zone is realized.
- Replaceable Heating Inductor
Apart from induction blanket (blanket type inductor), there are multiple heating inductors for choice including induction coil/cable, C-type inductor, plate type inductor, Split-core inductor, O type inductor, all of which are easily dismountable and reconnected to the power source. So the power source can be used for heating workpiece of different size and shape.
Accessories of induction heating machine:
We offer multiple accessaries like thermocouple, thermocouple welding machine, digital temperature-recorder, remote switchgear, output extension cable, insulation blanket, etc. Complete solution saves your time and ensures you to start work soon after received our delivery.
