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. 【Features】 - Short heating time, greatly reducing the time required for bolt tightening and loosening operations - Early detection of unexpected main engine malfunctions due to early release - Reduction of power plant downtime - Improvement of operational efficiency - Reduction of assembly and disassembly labor costs For more details, please contact us or download the catalog.

Mizeron is an environmentally friendly paint that contains no solvents at all, and it is a super thick film, long-term heavy-duty anti-corrosion paint that can be applied in a film thickness of 2 to 3 mm at once. 【Features】 ○ Solvent-free... Mizeron is a 100% solid polyurethane resin paint that uses no solvents, resulting in no solvent emissions from the painted film, making it environmentally friendly. ○ Super thick film type... Mizeron is applied using a two-component internal mixing paint machine. Continuous application allows for a thick film coating of 2 to 3 mm, which can shorten processes and reduce life cycle costs (LCC) as a long-term heavy-duty anti-corrosion specification. ○ Quick-drying... It becomes touch-dry in 30 to 60 minutes after application and hardens to a handleable state in 4 to 5 hours. It also cures in low-temperature environments, making it suitable for painting in cold regions. ○ Wide adaptability and workability... It can be applied to steel, galvanized surfaces, stainless steel, concrete, and more. The workability allows for coverage of 40 to 60 m² per hour (average film thickness of 2 mm per flat surface). ○ It does not require a primer, making it very economical. ● For more details, please contact us.
