Seamless / Welded / Fabricated
Types of Hastelloy buttweld fittings
-
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 Hastelloy Buttweld Fittings and Inconel Buttweld Fittings
While both Hastelloy and Inconel buttweld fittings offer high resistance to corrosion and temperature, they differ in composition and application. Mostly a nickel molybdenum alloy, hastelloy is a great option for chemical processing because of its exceptional ability to withstand extremely acidic and chemically charged environment. On the other hand, Inconel, a nickel-chromium alloy that is widely utilized in the power and aerospace industries provides exceptional resistance to oxidation and creep, particularly in extremely hot conditions. Inconel works better in oxidative environments, whereas hastelloy is typically more effective in reducing environments.

Applications of Alloy Hastelloy Buttweld Fittings
Alloy Hastelloy buttweld fittings find critical use across industries where corrosion, pressure, and temperature are key concerns. In chemical processing, they are essential for transferring aggressive fluids and acids without material degradation. These fittings are used in the petrochemical industry to handle complex hydrocarbons in harsh environments. They are perfect for structural and fluid transport systems in aerospace because of their strength-to-weight ratio and resistance to corrosion. Pharmaceutical plants use them to ensure hygienic, contamination-free operations, and marine applications benefit from their resistance to pitting and saltwater. Additional applications span food processing, power generation, and high-temperature service environments.
