Bolttech Mannings’ Induction Bolt Heating System can save you hours or even days during scheduled turbine outages. Our new bolt heating technology reduces average time from 45 minutes per bolt to 5 minutes per bolt, and the induction coils are cool to the touch creating a safer work environment. Our complete line of on-site services and equipment enable you to reduce downtime and make your next outage safe, quick and cost-efficient.
Bolttech Mannings’ patented Turbine Bolt Heating System utilizes variable-frequency inductive equipment and processes to thermally elongate turbine bolts in a fraction of the time normally required for the operation. These specially designed inductors make it possible for all heated bolting to be removed or tightened within one shift or less, and we have patented technology to accommodate any stud and nut arrangement.
Our proven method reduces outage time by days, which can save you millions of dollars in downtime. The process also minimizes safety concerns associated with the forceful removal of nuts with sledgehammers and slugging wrenches. Nuts can now be easily removed using simple hand tools, which reduces possible injury and lost man-hours.
Bolttech Mannings has developed a solution to the problems associated with water restrictions, which hinder the induction heating process. In nuclear environments the consumption of water may be restricted, and EPA regulations have required a more conscientious approach to the industry.
Our Closed-Loop Air to Water Chiller System minimizes water consumption by continuously circulating water through the system. Running clean water through the system can also improve product performance and reliability as well as eliminate cooling-water contamination associated with the use of “river water”.
The Self-Contained Mobile Induction Unit provides accelerated set-up and foregoes the need for plant power and water supply. Equipped with a generator and a closed loop chilling system, this state-of-the-art- unit can operate two 100Kw induction machines simultaneously.
Only Bolttech Mannings can deliver this degree of versatile induction services.
