Elvis Nickel Alloys is a leading Houston, USA–based manufacturer and supplier of Hastelloy flanges providing high-integrity pipe connection solutions for corrosive and high-temperature applications. Our Hastelloy flanges—weld neck, blind, slip-on, socket weld, threaded, and custom—are precisely machined to ASME/ANSI, ASTM, and international standards. Optimized for harsh chemical and thermal usage, these flanges provide superior sealing performance, strength of structure, and extended service life. Every unit is subjected to stringent quality tests to provide leak-free operation. Reliable in chemical processing, marine, pulp and paper, and power industries, our Hastelloy flanges ensure safe and reliable pipeline connection.
Hastelloy flanges are made from nickel-based alloys like C-276 and C-22, with about 57% nickel, 15–17% molybdenum, and 14–16% chromium, and iron and tungsten for increased strength. The materials are resistant to oxidizing and reducing agents, pitting, and crevice corrosion. Tensile strength of 95–125 ksi, yield strength of 40–60 ksi, and elongation of more than 30% constitute the mechanical properties. Heat-treated and solution-annealed to the specifications of ASTM B564, these flanges possess good impact resistance and ductility under mechanical stress even in harsh temperatures and corrosive environments.

The Hastelloy flanges have extensive application in chemical processing plants, acid plant units, and offshore units dealing with corrosive media. Typical uses are pipeline systems, reactor vessels, heat exchangers, and storage tanks where pressure and leak–proof joints are paramount. Their high corrosion resistance allows them to be used to join pipework that is subjected to chlorides, sulfur-containing compounds, and acidic blends. They find application in power plants within cooling systems and flue gas desulfurization. Pharmaceutical and food processing also utilize Hastelloy flanges for hygienic, contamination-free flow connections. Their mechanical strength and chemical resilience ensure long-lasting, maintenance-free operation.
