- Inconel 718 Buttweld Fittings
Midland Alloys Inc. is a trusted Indian manufacturer and global supplier of stainless steel Buttweld Fittings, offering a premium range of Inconel 718 Buttweld Fittings engineered for high-performance applications. These fittings are made with precipitation hardening element and a nickel-chromium alloy, which ensures dependable strength even in harsh environments. Known for their exceptional creep rupture strength up to 700°C, Inconel UNS N07718 Pipe Fittings are used in piping system that demand durability and heat resistance. These fittings which come in a variety of sizes and pressure ratings, satisfy a range of industrial requirements. They come in the following forms: couplings, tees, caps, reducers and elbows. For example directional flow control is made possible by Inconel 718 elbow fittings, and system pressure is effectively controlled by Inconel 718 reducer fittings, which control flow between pipes of varying diameters.

Types of Inconel 718 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 718 Buttweld Fittings and Inconel 625 Buttweld Fittings
Inconel 718 Buttweld Fittings are precipitation-hardened using niobium, titanium, and aluminum, offering superior tensile and yield strength along with better creep resistance. Inconel 625 Buttweld Fittings, on the other hand are stronger at high temperatures but more corrosion resistant due to their solid solution strengthening and higher molybdenum content. 625 is frequently used where corrosion control is a top concern even though 718 is recommended for aerospace and high stress systems.
