The benefits of induction brazing
Quality, speed, precision and safety, as well as cost and energy savings, are only a few of the numerous advantages of using eco-friendly induction heating for brazing jobs.
Oil and gas
EFD Induction has been helping oil and gas service companies since the mid 1990s.Induction heating is used within a variety of fields in the oil and gas industry.
For example:
- Post Weld Heat Treatment
- Pre Weld Heat Treatment
- Pre-heating before coating
- Tube bending
- Soldering
- Shrink fitting – bolts and nuts
- Shrink fitting – steam valves
- Shrink fitting – bearings
- Shrink fitting – hubs, gears, sprockets and impellers
- Shrink fitting – compressors and retaining rings
- Removal of rubber coatings
- Removal of glued parts
- Hardening of spray coatings
- Straightening

Solutions for the offshore industry
Flameless, fast, controllable and mobile—these are just some of the features that make induction perfect for a range of offshore applications.
Bolt heating
The use of induction heating for bolt expansion in high-pressure turbines is a powerful business tool. It’s faster than resistance and flame heating.
Coating removal and paint-stripping
Induction heating cuts coating removal times by as much as 90 per cent compared to alternative methods.

Onsite post-heating for the oil and gas industry is a growing application area for EFD Induction. The photo show a mobile Minac being used to treat pipelines.
Induction heating is increasingly used to remove the giant nuts and bolts in power stations' turbines.
Induction heating is a time- and labour-saving alternative to ineffecient flame and resistance heating for oil and gas processing plants, chemical plants and power stations.
The Coating Removal System is a game-changer that facilitates removal of coatings from carbon steel, structural steel and other metal substrates.
EFD Induction has worked closely with customers across the globe to develop the Coating Removal System.
The Coating Removal System is compact, light-weight, and easy to move around worksites.
Much easier clean-up. The coating material mainly peels off in flakes rather than being pulverized.
