Hastelloy Pipes and Tubes Supplier & Exporter in India
Jade Alloys manufactures, stocks and exports the complete family of Hastelloy pipes and tubes for the world’s most punishing corrosion and high-temperature service. Every Hastelloy pipe and tube leaves our Mumbai facility made from fully traceable nickel-alloy stock, solution-annealed, and inspected against international specifications, so what you order is exactly what arrives.
Hastelloy is a group of nickel-molybdenum and nickel-chromium-molybdenum alloys built to perform where stainless steel fails, including strong acids, wet chlorine, chlorides, sour gas and hot process streams. Their high molybdenum and chromium content forms a stable, self-healing passive layer that resists pitting, crevice corrosion and chloride stress-corrosion cracking in both oxidising and reducing conditions, while keeping the ductility, strength and weldability that fabricators rely on. Because a single grade such as C276 performs across so many media, it can replace several lesser materials in one plant, simplify inventory and cut unplanned downtime.
These alloys are strong and work-harden quickly, so machining calls for sharp tooling and controlled feeds and speeds, all readily achievable with the right equipment. Welding is well proven: gas tungsten arc welding (GTAW/TIG) and gas metal arc welding (GMAW/MIG) are standard, and correct interpass control plus, where specified, post-weld solution annealing preserve corrosion resistance and mechanical properties in the joint. Our low-carbon grades are engineered to hold their corrosion resistance even in the as-welded condition.
Hastelloy pipes and tubes are indispensable wherever aggressive chemistry meets heat and pressure, from chemical reactors and heat exchangers to corrosive-fluid pipelines, valves, offshore drilling equipment, power generation, pollution control and desalination. Across chemical processing, oil and gas refining, pharmaceutical manufacturing and aerospace engineering, they deliver the reliability, safety and long service life that keep critical infrastructure running.
As one of India’s trusted Hastelloy tubing suppliers, Jade Alloys backs every order with ready stock in the popular C276 and C22 grades, custom fabrication for special sizes and less common grades, complete EN 10204 3.1 / 3.2 documentation and on-time worldwide despatch, whether you need a single seamless pipe for a heat-exchanger repair or a bulk export lot of welded tube for a new plant.

How Hastelloy Pipes and Tubes Are Made
Melting & casting
Nickel and alloying elements are melted in an electric-arc / VOD furnace and cast into billet or plate.
Forming & welding
Billets are pierced and drawn for seamless product; plate is rolled and welded (TIG / laser / HF) for welded product.
Heat treatment
Solution annealing relieves forming and welding stresses and restores full corrosion resistance.
Cold drawing
Cold drawing over dies and plugs delivers tight tolerances, uniform microstructure and a fine surface finish.
Finishing & testing
Pickling, PMI, hydrostatic and NDT checks, marking, and export-grade packing before despatch.
Applications of Hastelloy Pipes and Tubes
- Chemical & petrochemical processing: reactors, scrubbers and transfer lines for acids, wet chlorine and mixed acids.
- Oil & gas / sour service: offshore, subsea and H₂S-bearing streams (NACE MR0175 / ISO 15156).
- Flue-gas desulfurisation (FGD): wet scrubbers with high chloride and sulfur.
- Marine & seawater: cooling systems and piping needing pitting / crevice resistance.
- Heat exchangers & condensers: high-temperature, corrosive process duty.
- Pharmaceutical & food processing: high-purity, contamination-sensitive systems.
- Pulp & paper: bleach plants and digesters.
- Power generation & aerospace: high-temperature strength and oxidation resistance (esp. Hastelloy X).
