Synergy Engineering Solution is a renowned manufacturer, stockist, and exporter of UNS N06022 Hastelloy C22 Plate Flanges, supplying premium-grade flanges across Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada, and several regions throughout Africa and worldwide. The company is recognized for delivering products that meet international standards and ensure superior performance in harsh and corrosive service conditions.
Hastelloy C22, designated as UNS N06022, is a nickel-chromium-molybdenum-tungsten alloy offering excellent resistance to both oxidizing and reducing agents, making it one of the most versatile corrosion-resistant materials available. C22 Plate Flanges are widely used in industries where protection against localized corrosion such as pitting, crevice attack, and stress corrosion cracking is vital. This makes them suitable for chemical processing, marine, pollution control, and flue gas desulfurization systems.
Synergy Engineering Solution manufactures a wide range of Hastelloy C22 flanges, including blind, slip-on, socket weld, lap joint, and threaded flanges. Each flange is carefully engineered and tested under strict quality control measures to ensure compliance with ASTM B564 and ASME SB564 standards. The company provides flanges in various pressure classes, sizes, and face finishes to cater to diverse industrial applications.
The chemical composition of Hastelloy C22—comprising approximately nickel (balance), 20–22.5% chromium, 12.5–14.5% molybdenum, 2.5–3.5% tungsten, with small amounts of iron, cobalt, and manganese—offers a unique balance of corrosion resistance. This ensures UNS N06022 flanges can withstand aggressive oxidizing media, mixed acid environments, and chloride-induced corrosion, making them highly reliable for offshore and chemical process industries.
Mechanically, Hastelloy C22 Plate Flanges deliver tensile strength around 690 MPa, yield strength of 283 MPa, elongation of 40–45%, and excellent toughness across varying temperatures. These properties ensure superior durability and consistent performance in high-pressure and high-temperature environments. They are widely utilized in reactors, heat exchangers, scrubbers, and piping systems handling aggressive chemicals.
Synergy Engineering Solution ensures that each shipment of UNS N06022 Hastelloy C22 Plate Flanges is supplied with Mill Test Certificates (MTC), third-party inspection reports, and complete export documentation. With a robust supply network and timely logistics, the company has built a strong global presence, making it a trusted supplier and exporter of Hastelloy C22 Plate Flanges across multiple industries.
