Ismail Flanges is a well-established Hastelloy Weld Neck Flanges manufacturer and supplier company located in Jakarta, Indonesia, that provides high-performance flanges for highly corrosive and high-pressure service. The flanges are manufactured from high-quality Hastelloy alloys like C22, C276, and C2000, which exhibit good resistance to chemical attack and thermal stability. With a long tapered hub, Hastelloy Weld Neck Flanges provide even stress distribution, hence perfect for demanding process systems. These components are made by Ismail Flanges according to international high-quality standards and supplied to industries like chemical processing, petrochemicals, marine, and pharmaceuticals.
Hastelloy Weld Neck Flanges consist of mostly nickel (60% maximum) with some molybdenum content (17% maximum), some chromium content (23% maximum), iron, and cobalt, varying with the Hastelloy grade. These constituents ensure exceptional resistance to reducing and oxidizing agents, along with strong mechanical properties. For instance, Hastelloy C276 contains tensile strength of about 690 MPa and a yield strength of 283 MPa. The long neck design provides a smooth flow of stress between the pipe and the flange, minimizing fatigue and increasing performance under high pressure and high-temperature conditions.
