What Are Incoloy Tube Fittings?

Incoloy tube fittings are mechanical connectors manufactured from engineered nickel-based alloys (commonly Incoloy 800, 800H, 825, and 925). These materials exhibit a unique blend of oxidation and carburization resistance, strength at high temperatures, and superior corrosion resistance in aggressive environments.

Tube fittings — including compression fittings, ferrule fittings, unions, elbows, tees, adapters, reducers, and plugs — are essential for joining tubing systems in instrumentation, process controls, hydraulic lines, and fluid delivery applications without welding.

Why Incoloy Materials Are Critical in UK Industries

In the UK, many industrial processes expose components to:

  • High temperatures (e.g., steam pipes, heat exchangers)
  • Corrosive media (e.g., chlorides, acids, sulfides)
  • Marine environments (saltwater exposure on platforms and ports)
  • High pressure instrumentation
  • Chemical process loops

Standard stainless steels such as 304 or 316 may not withstand such environments, especially at elevated temperatures or in the presence of aggressive chemicals. Incoloy alloys, with their advanced metallurgy, maintain structural integrity and corrosion resistance under these extremes.
