Induction Heating Stress Relieving Equipment for PWHT/Post Weld Heat Treatment
Brief introduction of our induction heating stress relieving equipment/PWHT post weld heat treatment machine:
our induction heating machine is made of high quality raw material with digital control, modular design, self fault feedback, and easy for operation, maintenance and repair. can be used for pipe stress relieving, PWHT, post weld heat treatment, applied in industries: offshore platform, oil and gas pipeline construction, power plant, etc
besides, our machine can also work very efficiently for pipe welding preheat, joint anti-corrosion coating.
Following is some of the working site:
induction heating machine can heat the whole part of flange, joint, with high efficiency, uniform heating, can heat both steel pipe and stainless steel pipes, and temperature recorder can show detailed temperature when working, and you can also print the PWHT curve for further research.

Features of induction heating stress relieving equipment for pipe post weld heat treatment:
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.
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 stress relieving equipment:
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.
