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

Introduction: When Standard Alloys Are Not Enough

In modern industries — from offshore drilling and petrochemicals to aerospace, chemical processing, and desalination — piping systems face extreme demands: high pressure, corrosive media, chloride-rich seawater, rapid thermal cycling, or cyclic loading. Under these harsh conditions, conventional stainless steels sometimes fail to deliver long-term reliability. That’s where duplex, super-duplex and precipitation-hardening (PH) stainless alloys step in.

Duplex alloy steels combine the strength of ferritic steels with the corrosion resistance of austenitic steels. Super-duplex and PH stainless steels elevate this further by improving chloride resistance, pitting resistance and mechanical strength. Tube fittings made from these alloys offer unmatched performance for critical applications.
