Hastelloy C22 Pipe Fittings, ASTM B366 UNS N06022 Fittings, Elbows, Tees, Reducers

Nickel alloy C22 is known for its excellent corrosion resistance in a wide range of aggressive environments, such as those containing oxidizing and reducing acids. These fittings can withstand harsh chemical conditions, ensuring long - term reliability and safety of the pipelines. With precise manufacturing processes, they fit well in different piping layouts, providing smooth fluid flow. Ideal for industries like chemical processing, petrochemical, and marine, mtsco nickel alloy C22 pipe fittings are a trustworthy choice.

Production advantages of MTSCO Pipe Fittings:

-Since 2010, MTSCO have held a controlling stake in Hongdi Pipe Industry through cooperation, obtaining ISO/PED/CRN/TS certifications and achieving a vertically integrated supply chain.

-Precision manufacturing is carried out using CNC lathes, 1000-ton hydraulic presses, and automated laser cutting systems.

-Our raw materials come from large factories such as Baosteel, TSINGSHAN, Yongxin... Each batch of raw materials requires MTC and PMI to ensure the quality of the raw materials. After the raw materials arrive, we conduct inspections such as PMI again to ensure they meet the requirements.

-Digital documents at each production stage supervised by factory engineers enable full-process traceability.

-Mandatory 100% pre-shipment inspections are carried out, including dimensional checks, non-destructive testing (ultrasonic testing/radiographic testing), and mechanical property testing.

Characteristic advantages of nickel alloy C22:

Nickel alloy C22 Pipe Fittings are made of nickel-chromium-molybdenum-tungsten alloy (UNS N06022). The ASTM B366 standard ensures that their chemical composition and mechanical properties meet the requirements of harsh industrial environments. This material exhibits excellent corrosion resistance in both oxidizing and reducing media, resists pitting corrosion, crevice corrosion, and stress corrosion cracking, and is suitable for pipeline systems containing highly corrosive media such as chloride ions, sulfuric acid, and hydrochloric acid.

Alloy C22 Elbows and Tees are manufactured using a precision cold forming process, with the inner wall smoothness reaching Ra ≤ 3.2μm, effectively reducing fluid resistance and preventing particle deposition. The gradual change structure design of Reducers can gently adjust the flow rate and reduce the risks of turbulence and cavitation. ASTM B366 UNS N06022 Fittings still maintain stable mechanical properties at a high temperature of 538°C and have excellent welding compatibility, supporting various welding processes such as TIG and MIG. After solution treatment and pickling passivation, a dense oxide film is formed on the surface of the products, making them suitable for high-pressure and high-temperature corrosive environments such as chemical industry, flue gas desulfurization, and nuclear power equipment.
