Welding preheating and post-heating is an important application field of induction heating.
The welding of steel after preheating can reduce the stress,improve the welding strength,
and prevent cracking.Post-heating is used for dehydrogenation,annealing,tempering,
normalizing and other processes.
Brief introduction of induction heating equipment for Wellhead preheating :
Induction heaitng equipment is designed and manufactured by Canroon used for Wellhead
preheating 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.
Besides, application of welding preheat, joint anti-corrosion coating and shrink fitting are also very efficient.
Overall pictures of induction heating equipment for Wellhead preheating :
Canroon induction heating equipment is designed and manufactured with high quality materials, it has
beautiful outlook, universal wheels for high movability, temperature recorder for precise control, display
panel to show working details, six thermocouple connections to record the temperatures, and remote
control for working site accordingly.
Technical parameters of induction heating equipment for post weld heat treatment:
36KW(duty cycle 100%) Frequency: 3-35KHz
Application details of induction heating equipment for Wellhead preheating :
Induction heating machine with temperature recorder for Wellhead preheating pipe PWHT/post weld heat
treatment works very well, insulation blanket can keep heat, from the temperature feedback from thermocouple,
we can see it is fast and uniform heating, etc. Following is picture of the detailed working site.
Features of induction heating equipment for post weld heat treatment:
- 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.
- Various Control Mode
- Fault Record
- Easy Maintenenace
- Self Diagnosis
- High Efficiency
- Uniform Heating
- Replaceable Heating Inductor
Apart from blanket type inductor, there are multiple heating inductors for choice including
C-type inductor,Split-core/ Clamp inductor, induction coil / cable, plate/ Flat type 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.
