Preheat & Post weld heating treatment (PWHT) induction machine weld preheat pipe heater

    Induction heating is a method to heat workpieces by generating eddy current inside through electromagnetic induction.Thanks to its advantages, this equipment is widely used for PWHT, preheat before welding, anti-corrosion coating mainly in oil and gas pipeline construction and offshore platform construction. Professional for heat treatment of copper and steel pipes, joints, flange,circular and longitudinal seams, pipeline support crack, rotor thermal, and so on.

The option parts of induction heating system:
Induction heating power
Induction coil (Clamp induction coil) or (Soft induction coil)
Extent cable for coil and the heating power
Temperature controller
PLC touch screen
Temperature recorder with printer
K type thermocouple
Extent cable and connector for thermocouple
Insulation Blanket

Induction heating power:

Other parts:

    The using fields involved are petrochemical, oil and gas pipelines, aerospace, shipbuilding, steel, tanks, boilers, vessels, pressure vessels, cylinders, metal structure, spatial structure, railway bridges, electricity water, mine construction, vehicle manufacturing, nuclear power, mining, plastics processing, energy saving process, mold, screw barrel industries,etc. 

 Pipeline coating preheat

welding preheating :

Uniform heat
Quick direct heat
Energy Saving 30-80%

Air cooling: working well at -10℃-40℃
Induction heating power: To heat the work job with insulation blanket around it. High heating speed and heating efficiency with little energy lost.
PLC touching screen: Intuitive to see and easy to operate.
Soft induction coil: Easy to wind on different work piece.
The Removable opening Induction coil: easy to operate and move.
Temperature recorder: Record the whole heating curve.
Temperature Controller: Heating according to the heating requirement details with the ±3℃ tolerance.

Induction heating power,flexible wire induction coil and thermocouple are the standard choice, generally choose the standard fumigation-free wood packing boxes for packaging.Other accessories, according to the specific items to choose the appropriate packaging.
