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.
Induction heating is used for welding preheating and post-heating.
It has the characteristics :
1. A good controllability
2. Can realize complex process program
3. Non-contact heating
4. Wide adaptability
5. high efficiency
6. Eneray density
7. Can realize on-line heating
Brief introduction of induction heating equipment for Wellhead preheating :
Induction heaitng equipment is designed and manufactured by Canroon used for Wellhead
preheating pipes post weld heat treatment / PWHT , widely applied and welcomed by oil&gas piping,
and power plant construction & repair.
We have movable type with40kw, 80kw, 120kw, 160kw .
For portable type, we have 5kw, 10kw. Such as 40kw induction heating equipment applied in PWHT,
the suitable pipe size with Diameter of 200-1600mm and Thickness of 25-120mm, heating temperature
will reach 788℃ at most. It can heat both carbon steel pipes and stainless steel pipes.
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:
(duty cycle 100%)
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, from the temperature feedback from thermocouple, we can see it is fast and
uniform heating, insulation blanket can keep heat, and the induction cable windings can be set according
to your pipe,heating temperature, etc. following is picture of the detailed working site.
Features of induction heating equipment for post weld heat treatment:
- Friendly Interface and Accurate Control
- Various Control Mode
- Fault Record
- Easy Maintenenace
- Self Diagnosis
- High Efficiency
- Uniform Heating
- 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.
