Nasib Tube Fittings, headquartered in Amman, Jordan, is a renowned manufacturer and supplier of high-performance industrial piping components. Among its advanced product range is the Hastelloy C22 Needle Valve, designed for precise flow control in highly corrosive and demanding environments. Known for its exceptional reliability, chemical resistance, and durability, this valve performs consistently even under extreme temperatures and pressures. Ideal for chemical, petrochemical, pharmaceutical, and offshore applications, the Hastelloy C22 Needle Valve reflects Nasib Tube Fittings’ commitment to superior engineering, premium alloy materials, and industry-leading quality standards.
The Hastelloy C22 Needle Valve is manufactured from Hastelloy C22, a nickel-chromium-molybdenum alloy enriched with tungsten for improved resistance to corrosion and pitting. It offers excellent tensile and yield strength, allowing it to withstand aggressive media and high-pressure systems. The valve maintains stability at elevated temperatures and resists both oxidizing and reducing environments. Precision machining ensures smooth operation, accurate flow regulation, and leak-free sealing. Its mechanical robustness, combined with outstanding corrosion resistance, makes it an ideal choice for critical fluid control systems in harsh industrial conditions.
