Large coupling removal is a common challenge in industrial maintenance, especially in environments where safety and precision are critical.
Traditional methods, such as flame heating or mechanical force, can be time-consuming and may introduce risks like uneven heating, material damage, or safety concerns for operators.
In a recent project at CSSC shipyard, they needed to remove a Ø400 mm coupling as part of their maintenance work.
Due to on-site safety requirements, flame heating was not considered a suitable option. The customer selected WTR medium frequency air-cooled induction heater to solve this problem, which method could ensure proper setup and application.
WTR after-sales teams offer technical guidance on site,Beyond selecting the right equipment, correct application and guidance play an important role in achieving reliable results.
With the induction heating equipment in place, the coupling was heated evenly and reached the required temperature in a controlled manner. The entire heating and removal process took approximately 6 minutes. There was no need for open flame, and the temperature could be adjusted based on the actual condition of the component. Most importantly, the coupling was removed without any damage to the part or surrounding equipment.
Induction heating can improve both efficiency and safety in coupling removal and other maintenance tasks. For industries such as shipbuilding, steel processing, and heavy machinery maintenance, induction heating is becoming an increasingly practical method for shrink fitting and disassembly work.
