Seamless / Welded / Fabricated
Types of Inconel 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 Inconel Buttweld Fittings and Incoloy Buttweld Fittings
Inconel Buttweld Fittings and Incoloy Buttweld Fittings are both nickel-based, but they differ in chemical composition and performance characteristics. Inconel, especially grades like UNS N06600 (DIN 2.4816), contains a higher percentage of nickel, giving it superior resistance to extreme heat and aggressive oxidizing environments. In contrast, Incoloy has higher iron content, which makes it cost-effective for moderate temperatures but less resistant to extreme thermal cycling. While Inconel Alloy B366 Buttweld Fittings are ideal for aerospace, nuclear, and furnace components, Incoloy is more suitable for marine and chemical processing where cost efficiency matters alongside corrosion resistance.
