Hastelloy Pipes and Tubes, particularly grades C22, C276, and B2, are widely recognized for their exceptional resistance to highly corrosive environments, making them an indispensable choice across multiple industries. Neonox Overseas, a trusted supplier of high-performance nickel alloy products, offers premium-quality Hastelloy C22/C276/B2 Pipes and Tubes that meet international standards like ASTM, ASME, and DIN. These alloys are engineered to provide durability, resistance to pitting, stress corrosion cracking, and oxidizing as well as reducing agents.
Hastelloy C22 is a versatile nickel-chromium-molybdenum alloy that provides outstanding resistance against oxidizing chemicals like chlorine, nitric acid, and ferric salts. It is highly effective in preventing localized corrosion, making it a preferred material for chemical processing, pharmaceutical equipment, and marine environments. The pipes and tubes of Hastelloy C22 are available in seamless, welded, ERW, and fabricated types, ensuring flexibility in application.
Hastelloy C276 is one of the most popular alloys, known for its unmatched resistance to a wide range of strong oxidizers and reducing agents. It resists the formation of grain boundary precipitates in the weld-heat affected zone, making it highly suitable for as-welded conditions. Its applications include pollution control, power generation, pulp and paper processing, and chemical reactors. Neonox Overseas supplies Hastelloy C276 Pipes and Tubes in a variety of sizes, wall thicknesses, and specifications, suitable for both high-pressure and low-temperature services.
Hastelloy B2, a nickel-molybdenum alloy, offers excellent resistance to hydrochloric acid in all concentrations and temperatures. It has improved thermal stability compared to its predecessor alloys and exhibits resistance to hydrogen chloride gas and sulfuric acid. Hastelloy B2 Pipes and Tubes are commonly used in chemical industries, especially in the manufacture of organic and inorganic chemical compounds where aggressive reducing agents are involved.
At Neonox Overseas, the offered Hastelloy C22/C276/B2 Pipes and Tubes are available in seamless, welded, ERW, EFW, and fabricated forms.
