Hastelloy Weld Neck Flanges are top-notch components crafted for high-performance piping systems that operate in extreme conditions. Made from Hastelloy alloys like C22, C276, and C2000, these flanges boast remarkable resistance to corrosion, oxidation, and chemical damage. Uday Flanges, a trusted manufacturer and supplier based in Dubai, UAE, delivers precision-engineered Hastelloy Weld Neck Flanges that adhere to international standards. Perfect for high-pressure and high-temperature applications, they find their place in industries such as chemical processing, pharmaceuticals, marine, and power generation. Their long tapered hub ensures even stress distribution, making them perfect for critical pipeline connections.
Hastelloy Weld Neck Flanges are primarily composed of nickel-molybdenum or nickel-chromium-molybdenum alloys, depending on the specific grade (like C276 or C22). These alloys provide outstanding resistance to pitting, stress-corrosion cracking, and oxidation. A typical composition features around 57% nickel, 15–22% molybdenum, 14–16% chromium, along with trace elements of iron, cobalt, and tungsten. In terms of mechanical properties, they can achieve tensile strength up to 690 MPa and yield strength around 283 MPa, showcasing excellent ductility and toughness even at high temperatures. These flanges are perfect for corrosive and high-stress environments, maintaining their structural integrity under both mechanical and thermal loads.
