Our weld neck flanges meet international standards such as ASME, ANSI, and ASTM, guaranteeing top-notch quality and precise dimensions. Perfect for critical sectors like chemical processing, aerospace, offshore, and nuclear industries, Harsh Flanges delivers reliable, leak-proof Inconel weld neck flanges that fulfill stringent performance criteria.
Inconel Weld Neck Flanges are crafted from high-performance nickel-chromium alloys, including Inconel 600, 625, or 718. These alloys generally consist of 58–72% Nickel, 14–23% Chromium, and may also contain Molybdenum, Niobium, and Iron. Inconel is known for its impressive tensile strength (up to 1,030 MPa), yield strength (up to 760 MPa), and resistance to high temperatures. These flanges excel in resisting oxidation, carburization, and stress-corrosion cracking in extreme chemical and thermal settings. The long tapered hub design of weld neck flanges ensures structural integrity and effective stress distribution, making them perfect for high-stress and high-pressure pipeline systems.
Harsh Flanges, a leading supplier in Mumbai, India, offers an extensive selection of Inconel weldneck flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.
