Induction bolt heating service
Induction bolt heating involves heating drilled stud bolts to obtain elongation. Thus, it only takes a few minutes to heat them evenly and safely. This process is 2 to 3 times faster than conventional heating means such as heating rods
A proven method
In 2004 we launched our first machines and our first interventions. Since then, we have traveled across Europe and even the world: Japan, China, USA, Mexico, Turkey, UK, France…
Our main induction tightening operations are carried out on turbines (hydraulic, steam, gas) and compressors of all sizes.
The advantages of our induction bolt heating service
- 6 machines in stock and more than 60 inductors
- 24/7 service on-site
- Easy to set up and use: all you need is a 380 volts 32A outlet
- Light & compact design, equipped with 360° wheels
- Cooling system integrated in the machine
- Timer integrated to control heating time
- User-friendly, easy to operate with automatic or manual power regulation
- 10 meters length of coaxial cable to access both sides of the turbine
- No exceeding of the Curie point (no material transformation)
- No burning risk as inductor remains cold
- All sizes inductors manufacturing, in 48 hours on demand
- Only heat the center of the bolt, for accurate tightening and to minimize heat dispersion
- Quick heating time
