The Variable Radius Induction Preheating Device is used for preheating before welding. In automatic welding operations, where the pipe rotates around the axis, traditional winding-type heating methods may not meet the requirements. Therefore, a variable radius induction preheater is used to adapt to the preheating requirements of pipes with different diameters. The induction heater does not directly contact the pipe, ensuring that the pipe is heated while the weld seam is being welded. This avoids the need to remove the heating cables during welding, which is required in traditional winding-type heating methods, preventing interruptions in the heating process and difficulties in controlling interlayer temperatures, thereby effectively avoiding associated quality issues.
The variable radius inductors come in two specifications, suitable for pipe diameters ranging from 2 to 12 inches and 12 to 32 inches, respectively. Each type of inductor is made of insulating material with sufficient strength to support the induction heating cable reel and control the radius bending changes. The induction heating cable is connected to the power supply via a special protective aviation plug and extension cable to form a circuit for heating the workpiece. With the design of the variable radius induction preheater, the number of heating cables used is greatly reduced, resulting in low operating costs. Additionally, the design of the variable radius induction preheater eliminates the need for manual labor and time required for wrapping and removing heating cables directly from the pipe.
When the main unit's power meets the requirements, in certain specific conditions (such as fitting-up preheating, simultaneous preheating of two weld seams, etc.), a one-to-two method can be implemented to heat both sides of the weld seam or two weld seams simultaneously.
The system can digitize and record the entire heating curve process. It employs an industrial control touch screen to display real-time temperature curves for up to 6 channels and record and save the data. Real-time monitoring and USB interface enable data retrieval and storage, ensuring effective management of equipment operation status.
This station is suitable for preheating pipelines in industries such as power plants, petroleum, petrochemicals, shipbuilding, etc., and serves as an efficient auxiliary equipment for pipeline processing.
