Induction heating in the oil and gas industry

Oil and gas

EFD Induction has been helping oil and gas service companies since the mid 1990s.
Close

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

Postheating with induction heating

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 bolt heating

Induction heating is increasingly used to remove the giant nuts and bolts in power stations' turbines.

Induction heating at oil processing plants

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.

Induction heating - paint and coating removal

The Coating Removal System is a game-changer that facilitates removal of coatings from carbon steel, structural steel and other metal substrates.

Paint and coating removal with induction heating

EFD Induction has worked closely with customers across the globe to develop the Coating Removal System.

Paint and coating removal with induction heating

The Coating Removal System is compact, light-weight, and easy to move around worksites.

Paint and coating removal with induction heating

Much easier clean-up. The coating material mainly peels off in flakes rather than being pulverized.
