Significantly contributes to the reduction of regular inspections, ensuring the safety of workers, and maintaining the integrity of bolts.
The bolt heater utilizing high-frequency induction heating performs the opening and closing (tightening and loosening) of hole bolts in turbine chambers, valves, flanges, pressure vessels, water turbines, rolling machines, etc., quickly and safely without damaging the bolts. The input power is set to ensure that the temperature difference between the inside and outside of the bolt does not exceed the allowable stress (Patent No. 03396344), and the structure of the heating coil, consisting of a reciprocating conductor in a semi-circular shape, provides high heating efficiency (Patent No. 2882962). Additionally, interference from objects such as the upper part of the bolt can be avoided with flexible heating coils. This significantly contributes to reducing regular inspection times, ensuring worker safety, and maintaining the integrity of the bolts. Kyokuto Sangyo Co., Ltd. offers equipment rental and dispatches technical instructors.
