Bolt heater
Heater specialized for tightening bolt strength (for marine internal combustion engines, power generation turbines, etc.)
This is a heater specialized for tightening bolt strength. A hole is drilled to insert the heater into the center of the bolt, and by heating it, the bolt expands, allowing for a tighter fit. After that, the power to the heater is cut off, and as the bolt cools, it contracts, achieving the same effect as a more secure tightening. It is widely used in areas where strong tightening of bolts is required, such as in marine internal combustion engines, power generation turbines, high-pressure presses, and high-pressure valves. Our bolt heaters have been designed and manufactured in-house for many years, giving us unique know-how. We can propose products that meet customer needs, including heater diameter, heater length, electrical capacity, and operating voltage.
