Benefits of Incoloy High‑Pressure Forged Fittings
Incoloy high-pressure forged fittings provide dependable performance under demanding situations. Here’s why industries prefer them:
- High Strength and Durability: Incoloy 800 socket weld forged fittings offer excellent strength for tough, high-pressure jobs
- Corrosion Resistance: The nickel-iron-chromium mix protects against oxidation, acid attack, and general corrosion
- High-Temperature Performance: Suitable for heat exchangers and reactors, particularly Incoloy 800HT forged fittings
- Weldability and Formability: Easy to fabricate into different forged fitting types without losing strength
- Chloride Stress Corrosion Cracking: Resistant to chloride-induced cracking in marine or chemical plants
Incoloy 800 and Incoloy 825 forged fittings differ primarily in their chemical composition and corrosion resistance. Incoloy 800 forged fitting is an iron, nickel, and chrome alloy designed to offer high-temperature strength and exceptional resistance to oxidation and carburization, making it perfect for heat exchangers and furnace components. In contrast, Incoloy 825 forged fitting contains extra elements including molybdenum, copper and titanium, which increase its resistance to reducing acids, stress-corrosion cracking, and pitting, especially in harsh corrosive environments such as chemical processing and marine applications. While both alloys have strong mechanical strength and corrosion resistance, Incoloy 825 performs better in harsh chemical environments than Incoloy 800.

Types of Incoloy 800 Forged Fittings
Manufacturing Types
-
Threaded Forged FittingsDesigned with internal or external threads, these fittings allow quick assembly and disassembly without welding.
-
Socket Weld Forged FittingsThese fittings are joined by inserting the pipe into a recessed area of the fitting and welding around it, ensuring strong, leak-proof joints.
-
Screwed FittingsSimilar to threaded types, screwed fittings are connected using screw threads, making installation simple and cost-effective.
-
BSPTBushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
-
NPTEnd caps are used to seal a pipeline's end, shielding it from impurities and guaranteeing closed systems' safety.
Forms
-
Forged ElbowElbows, which come in 45° and 90° varieties shift the direction of flow with little pressure loss.
-
Forged BushingBushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
-
Forged TeeUsed to split or combine flow across three directions essential for branching pipeline.
-
Forged CouplingOffer a safe connection between two pipes; threaded and socket-welded options are available.
-
Forged PlugClose open pipe ends which are frequently used for isolation or testing.
-
Forged CrossWith four openings, cross fittings help connect four pipes used when fluid distribution needs to occur in multiple directions.
