We offer a full range of precision-manufactured elbows, tees, reducers, stub ends, caps, and more across multiple Inconel grades to suit your project needs.
Why Inconel Pipe Fittings Matter
Inconel alloys combine nickel, chromium, and additional alloying elements to deliver unmatched performance in challenging environments. These fittings resist oxidation, corrosion, stress corrosion cracking, and maintain strength at high temperatures far beyond what conventional stainless steels can handle.
That’s why industries rely on Inconel for downstream and upstream oil & gas systems, offshore platforms, heat treatment units, chemical reactors, and marine infrastructure.
Our Inconel Pipe Fitting Grades
Inconel 600 Pipe Fittings
Designed for high temperature and oxidizing atmospheres, Inconel 600 fittings handle thermal stress without degradation. Best for heat exchangers, furnaces, and corrosion-exposed piping where oxidation resistance and weldability are key.
Inconel 625 Pipe Fittings
Inconel 625 stands out for exceptional corrosion resistance and high tensile strength across a wide temperature range. These fittings perform in marine, chemical processing, and offshore environments, resisting pitting, crevice corrosion, and stress corrosion cracking.
Inconel 718 Pipe Fittings
When you need outstanding mechanical strength and creep resistance, Inconel 718 is the choice. It’s heat-treatable and fatigue resistant, so it’s widely used in aerospace, gas turbines, and power generation systems where structural stability at elevated temperatures is crucial.
Inconel 725 Pipe Fittings
Inconel 725 brings together the corrosion resistance of 625 with boosted strength from precipitation hardening. That mix makes it ideal for sour service, subsea applications, and environments with high chloride concentrations, where both durability and corrosion protection are non-negotiable.
Inconel 800 & 800H Pipe Fittings
When thermal stability is the priority, Inconel 800 and 800H deliver. These grades withstand oxidation, carburization, and long-term high-temperature exposure, making them suited to furnaces, heat exchangers, petrochemical heaters, and power plant piping. The “H” variant adds enhanced creep and rupture strength for continuous high-heat service.
Common Inconel Fitting Types
We supply a complete lineup of Inconel pipe fittings, including:
• Elbows – change flow direction with minimal turbulence
• Tees & Crosses – branch pipelines efficiently
• Reducers – adapt piping sizes cleanly
• Stub Ends – pair with lap joint flanges for modular systems
• Caps & Plugs – protect or terminate pipe ends
• Couplings & Unions – secure, leak-resistant connections
Each product is manufactured to precision tolerances and compatible with relevant industry standards for seamless integration.
