UNS N06022 Hastelloy C22 Weld Neck WNRF Flanges are high-performance, corrosion-resistant components designed for critical industrial applications that involve highly aggressive chemical environments. Made from Hastelloy C22, a versatile nickel-chromium-molybdenum alloy with additions of iron and tungsten, these flanges offer outstanding resistance to a wide range of corrosive substances, including oxidizing and reducing agents. The Weld Neck Raised Face (WNRF) design is ideal for high-pressure systems, as the long tapered hub provides structural reinforcement and ensures leak-proof and reliable connections in pipelines.
Synergy Engineering Solution is a well-established manufacturer, stockist, and exporter of UNS N06022 Hastelloy C22 Weld Neck WNRF Flanges, known for supplying quality-assured, precision-engineered flanges that conform to international standards such as ASTM B564 and ASME B16.5. With advanced manufacturing facilities and a strong technical team, Synergy ensures that each flange undergoes rigorous quality control checks to meet the demanding specifications of industries like chemical processing, pollution control, pharmaceutical, and marine engineering.
As a global supplier, Synergy Engineering Solution exports these flanges to major international markets including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada, and various regions across Africa and worldwide. Their extensive global distribution network, reliable logistics, and customer-centric approach ensure timely delivery and consistent product availability, making them a preferred partner for clients involved in large-scale and critical infrastructure projects.
Hastelloy C22 (UNS N06022) is widely recognized for its superior corrosion resistance in both oxidizing and reducing media, making it an excellent choice for use in harsh environments like acidic gas scrubbers, waste treatment facilities, and nuclear fuel processing. These flanges exhibit resistance to pitting, crevice corrosion, and stress corrosion cracking—conditions that are common in highly corrosive operating conditions. The high nickel and chromium content enhances the overall stability of the material in diverse temperature and chemical exposure settings.
Synergy offers these flanges in a wide range of sizes, pressure ratings (150#, 300#, 600#, etc.), and face types (RF, RTJ), tailored to customer requirements. Each product is supported by mill test certificates, third-party inspection options, and full traceability documentation to ensure transparency and compliance with project specifications. Custom machining and special coating services are also available on request.
UNS N06022 Hastelloy C22 Weld Neck WNRF Flanges from Synergy Engineering Solution are a reliable and durable solution for the most challenging industrial applications. With a proven track record of quality and global reach, Synergy continues to be a trusted name in the supply of corrosion-resistant alloy flanges to industries where performance and safety cannot be compromised.
