Where are Induction heating machine with blanket coil/inductor used?

Induction heating is used extensively in the metalworking industry to heat metals for hardening,soldering, brazing,

and tempering and annealing.Thanks to its advantages, this equipment is widely used for PWHT(post welding

heat treatment),welding preheat, joint anti-corrosion coating in many different fields mainly in oil and gas

pipeline construction.

About Canroon's CR2000 series Induction heating machine with blanket coil/inductor 

CR2000 series medium frequency induction heating system is designed and manufactured by Canroon, specially

for using of welding preheat, post weld heat treatment (DHT dehydrogenation heat treatment, ISR intermediate

stress relief), and joint anti-corrosion coating.

Application industries: offshore platform, power station, oil and gas pipeline construction, etc

Applications: pipe welding preheat, PWHT/ post weld heat treatment, joint anti-corrosion coating, etc

Features:digital control, self-fault diagnosis, modular design, fault code feedback, high efficiency, etc

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.

Induction Heating Power Source:

CR2000 induction heating generatore covers power 5KVA/10KVA/40KVA/80KVA/120KVA.

All designed with perfect portability and compact in size.

Accessories of the CR2000 series Induction heating machine with blanket coil/inductor 

for pipe / tube welding preheat & PWHT:

Our induction heater uses new technology with IGBT module, digital control, and modular design,

can be used for welding preheat, PWHT, stress relieving, etc, also efficient for joint anti-corrosion coating.

Customized Inductor:

Canroon provide customized inductor to adapt various workpieces, and ensure easier operation and higher

working efficiency.

 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.

Applications of the CR2000 series Induction heating machine with blanket

coil/inductor for pipe / tube welding preheat & PWHT:

CR2000 is widely used and welcomed by oil&gas piping, and power plant construction & repair.
Application of shink fitting for motor stator is also very efficient. Such as Preheating for circular seam /

longitudinal seam welding;Preheating for joint anti-corrosion coating;Annealing ；PWHT.

Features:

• High Efficiency

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.

• 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.

• Fault Record

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.

• Various Control Mode

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 of constant

power and power VS time. Each mode offers different parameters to set. Thus brings the benefit of wide

applicability and precise control.

• Easy Maintenenace

Due to modular design, the maintance will be easy and low-cost.

• Self Diagnosis

Once fault occurs, CR2000 will act with display of fault code, which was detailed explained in the manual book.

• Uniform Heating

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.
