Types of Incoloy Buttweld Fitting
-
Elbow (90°, 45°, Long Radius, Short Radius)Modifies the pipeline's flow direction at predetermined angles with regulated radii.
-
Tee (Equal Tee, Reducing Tee)Adjusts the size of the main and branch lines to split or combine flow at 90° intersections.
-
A reducer (eccentric or concentric)joins pipes with varying diameters while preserving flow offset or alignment.
-
stub endIn non-permanent piping configurations, the stub end (long or short) connects to lap joint flanges for disassembly.
-
Return Bends (180° bend)Redirects flow by 180 degrees, allowing the pipeline to reverse direction.
-
Cross (Equal Cross, Reducing Cross)Provides multidirectional flow by joining four pipes at right angles.
-
pipe capTo stop flow or pressure, an end cap also known as a pipe cap, seals the pipe's open end.
-
Bend (3D, 5D, Custom Radius)This tool uses predefined or custom radii to gradually change the direction of pipelines.
-
nipplesShort pipe segments called "nipples" (also known as "barrel" or "swage") are used to join two fittings or pipes.
-
Collar / CouplingLinks two pipe sections in a straight run with a secure and leak-free joint.

Difference Between Incoloy Buttweld Fittings and Inconel Buttweld Fittings
While both Incoloy and Inconel Buttweld Fittings belong to the nickel-based alloy family, their performance differs based on alloy composition. Because of their higher iron content, Incoloy Buttweld Fittings (like Incoloy 800, 825 or UNS N08800) are better suited for applications requiring resistance to oxidation and stress corrosion cracking at temperatures ranging from moderate to high. On the other hand, Inconel Buttweld Fittings which are made mostly of nickel and chromium, perform better in corrosive and extremely high-temperature conditions, particularly when under pressure. While Inconel works well in high-pressure systems and aggressive thermal cycling, Incoloy variants are frequently utilized in sulfur-rich environments and acidic environments.

Applications of Incoloy Buttweld Fittings ASTM B366
Incoloy Buttweld Fittings play a crucial role in multiple high-demand industries due to their strength and corrosion resistance. In chemical processing plants, they manage aggressive chemicals and fluids. The oil & gas sector employs them in pipelines and offshore rigs for their resistance to sour gas and seawater corrosion. In power generation, especially in boilers and heat exchangers, they handle high temperatures without structural deformation. Refineries and petrochemical units use them for reliable performance in hydrocarbon and sulphur-rich environments. These fittings are also found in water treatment plants, where they endure harsh cleaning agents and continuous operation cycles.
