Hastelloy Flanges

ARK Stainless Inc. is a leading manufacturer and supplier of high-performance Hastelloy Flanges, specifically engineered to excel in high-pressure, stress, and corrosive environments. Known for their leak-proof design and exceptional durability, these flanges are perfect for a broad range of industrial applications such as fluid and gas distribution systems.

We offer top-grade materials such as Hastelloy C22 and Hastelloy C276, celebrated for their outstanding resistance to oxidation, corrosion, and harsh chemicals. These alloys provide moderate tensile and yield strength, high melting points up to 1443°C (2430°F), and elongation capacities up to 30%. Our Hastelloy flanges are available in multiple forms, including Weld Neck, Slip-On, Socket Weld, Blind, and Threaded types. Manufactured to global standards like ASTM B564 / ASME SB564 and dimensional specifications such as ASME B16.5, B16.47 Series A & B, and MSS-SP-43, they ensure excellent performance and quality for critical sectors like petrochemicals, nuclear power, acid processing, and oil refineries.

Hastelloy C22 / C276 Flanges

Hastelloy C22/C276 Flanges are available in various types, each serving a specific function. For instance, weld neck flanges are designed for high-pressure applications, while slip-on flanges are ideal for applications where ease of installation is required. Blind flanges are used to close the end of a pipeline, and socket weld flanges provide a leak-proof connection.
Additionally, threaded flanges are used for pipe systems where welding is not preferred. Other variations of Hastelloy flanges include lap joint flanges, ring type joint (RTJ) flanges, and others that meet specific project requirements.
These Hastelloy C22/C276 Flanges are manufactured using processes like forging, casting, and machining. After production, they undergo a series of rigorous tests and come with essential certifications, including raw material purity reports, third-party inspection certificates, radiography test results, and dimensional inspection certificates.
