Veer Flanges stands out as a top manufacturer and supplier of Stainless Steel Weld Neck Flanges in Kolkata, India. We specialize in providing high-performance flange solutions tailored for critical applications in tough environments. Our flanges are designed with a long tapered hub and are butt-welded to the pipe, ensuring they maintain structural integrity while minimizing stress concentration. Crafted from premium-grade stainless steel, our weld neck flanges boast exceptional resistance to corrosion, high temperatures, and pressure, making them perfect for severe service conditions. We adhere to global standards like ASME B16.5 and ASTM A182, serving industries such as oil & gas, petrochemicals, power, and marine.
Our Stainless Steel Weld Neck Flanges are made from high-quality alloys, including 304, 304L, 316, 316L, or 321, which contain 18–20% chromium, 8–12% nickel, and optional molybdenum for added corrosion resistance. These flanges deliver impressive tensile strength ranging from 485 to 620 MPa, yield strength from 170 to 310 MPa, and elongation of about 30–35%, depending on the specific grade. Their butt-welded design guarantees leak-proof connections and outstanding performance under high mechanical and thermal stress. The stainless steel composition ensures resistance to oxidation, scaling, and chemical attack, making them perfect for long-term industrial applications.
