Advanced Induction Heating Machine for Oil & Gas Pipeline Welding

Product Description

Introducing our top-of-the-line Joint Flange Pipe Induction Heating Equipment, an essential tool for Stress Relieving and Post Weld Heat Treatment (PWHT) applications. This High-Quality PWHT Machine promises to deliver superior performance and reliability, ensuring your welding processes are executed with unparalleled precision and effectiveness.

Induction Generator

 

Core Function: As the pivotal "brain" and "heart" of our system, this component ingeniously transforms standard power-frequency AC into medium-frequency
(1-20kHz) AC. It channels this power seamlessly to the induction component, thereby creating a robust magnetic field essential for efficient operations.
Application Details: Our state-of-the-art equipment boasts a sophisticated built-in PLC control system that enables intricate multi-stage heating process curves. This ensures an unparalleled level of precision for automatic heating operations.
The main unit is designed with a sleek touchscreen control panel and an emergency stop button for enhanced user safety. Swivel casters afford it excellent mobility on construction sites. With a power output range of 10kW to 120kW, this machine is equipped to meet the diverse heating needs of various pipe diameters and thicknesses.

Induction heat blanket

 

Core Function: Our innovative flat blanket-style induction heating component is expertly crafted for the targeted heating of flat surfaces or workpieces with large curvatures.

Application Details: This component can be seamlessly placed on flat workpieces such as steel plates, storage tank walls, and
boiler drums, delivering expansive heating coverage while ensuring meticulous temperature uniformity. It shines in applications requiring welding preheating,
overall stress-relief heat treatment of substantial pressure vessels, and in the heat correction of ship decks. Compared to traditional winding-type
induction cables, it offers a significant boost in installation efficiency for flat workpieces.

Extend cable

Core Function: This essential extension cable offers an extended connection between the induction power supply and the heating component.

Application Details: Strategically designed for on-site operations, it ensures the power supply unit is positioned in a dry, secure, and conveniently accessible
location, while the workpiece may be situated at various challenging positions, be it elevated heights, deep pits, or distant spots. This extension
cable (spanning 5-20 meters) substantially broadens the equipment's operational range, enhancing both flexibility and safety during
construction tasks.

Soft Induction cable
Core Function: This core execution element of the induction heating system is depicted by the blue flexible cable in the image.
Application Details: Ingeniously designed for versatility, it wraps around metal workpieces of varying shapes and pipe diameters, including straight pipes, elbows, tees, and flanges. Post power application, it generates an alternating magnetic field, inducing the metal workpiece to heat through electromagnetic induction (non-contact heating). Compared to conventional rigid coils, it facilitates remarkably fast installation and removal, ideal for outdoor field operations, and is widely trusted for pipeline welding preheating.
Core Function: This flat blanket-style induction heating component is engineered for heating flat surfaces or workpieces with substantial curvatures.
Application Details: Seamlessly aligning on surfaces of flat workpieces like steel plates, storage tank walls, and boiler drums, it guarantees expansive heating coverage and exceptional temperature uniformity. Highly effective for welding preheating, comprehensive stress-relief heat treatment of large pressure vessels, and ship deck heat correction. Compared to winding-type induction cables, this option offers superior installation efficiency on flat workpieces.
