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.

basic information
A heater insertion hole is opened in the center of the bolt, and the heater is inserted and powered on (heated). When heated, the bolt expands due to thermal expansion. At this time, the bolt is tightened, and when the heater power is turned off, the bolt will contract upon returning to room temperature, allowing for a strong tightening effect.
