Hastelloy B2 Couplings

A Coupling is a critical forging pipe fitting used to securely connect two lengths of pipe or components, commonly found in socket-weld or threaded configurations for small-bore piping systems. When manufactured from Hastelloy B2 (UNS N10665), these couplings are engineered to exhibit superior resistance to severe corrosion. Hastelloy B2 is a nickel-molybdenum alloy uniquely suited for strong reducing chemical services, providing excellent stability against hydrochloric acid (HCl) and sulfuric acid across various concentrations and temperatures. Zeron Fastners is a leading manufacturer and supplier of these specialized fittings in India, ensuring the integrity and longevity of pipelines in the most demanding process industries.
