Hastelloy steel pipe and fittings

Hastelloy pipe and fittings are corrosion-resistant nickel-based alloy products designed for piping systems exposed to aggressive chemical media, high temperatures, and demanding operating conditions. Depending on the alloy grade and manufacturing method, Hastelloy products are available as seamless pipe, welded pipe, and butt-weld or forged fittings.

Material and Standards

1. Hastelloy steel pipe

Hastelloy steel pipes are available in seamless and welded forms, with Hastelloy C276 and Hastelloy C22 as the main material grades. These nickel-chromium-molybdenum alloys provide excellent corrosion resistance and mechanical performance for demanding industrial piping systems. Applicable standards include ASTM B622 and other relevant ASTM/ASME specifications according to the product type and project requirements.

2. Hastelloy pipe fittings

Hastelloy pipe fittings are available in elbows, tees, reducers, caps, bends, and other configurations for connecting and directing Hastelloy piping systems. They are manufactured from corrosion-resistant nickel-based alloys and can be supplied according to applicable international standards, including ASTM B366/B366M and ASTM B462.

Applications

Hastelloy steel pipes and fittings are widely used in:

Chemical Processing: Acid reactors, heat exchangers, and scrubbers.
Marine Industry: Seawater systems and desalination equipment.
Aerospace: High-temperature and corrosion-resistant components.
Power Generation: Flue gas desulfurization systems and heat recovery units.
Pharmaceutical Industry: Sterilization systems and hygienic piping.
Pollution Control: Stack liners and waste treatment systems.
