Hastelloy B2 Weld Neck Flanges

A Weld Neck Flange is easily recognizable by its long tapered hub which is butt-welded to the pipe. This design provides reinforcement and distributes stress across the pipe wall, making it ideal for high-pressure, high-temperature, and fluctuating temperature applications. When forged from Hastelloy B2 (UNS N10665), these flanges are specifically engineered for service in the most aggressive reducing chemical environments. The high molybdenum content ensures the material is virtually immune to non-oxidizing acids, notably hydrochloric acid (HCl) and sulfuric acid (H₂SO₄), even at concentrations and temperatures where other metals fail. Zeron Fastners is a trusted manufacturer and supplier of these specialized nickel alloy weld neck flanges, guaranteeing leak-free, structurally sound connections in critical chemical process lines.
