Vishal Flanges stands out as a top-notch manufacturer and supplier of Stainless Steel Weld Neck Flanges, proudly based in Delhi, India. They specialize in providing high-quality piping solutions tailored for high-pressure and high-temperature applications. These flanges feature a long tapered hub and are butt-welded to the pipe, ensuring excellent stress distribution and structural integrity. Crafted from premium stainless steel grades like SS 304, 304L, 316, and 316L, they boast impressive corrosion resistance and durability, making them perfect for critical service conditions. Vishal Flanges ensures that their weld neck flanges meet international standards such as ASME, ANSI, and DIN, catering to the petrochemical, power, marine, and industrial sectors.
Stainless Steel Weld Neck Flanges are normally manufactured from alloys like 304, 316, or 317 stainless steel with a composition high in chromium (18-20%) and nickel (8-12%) and traces of molybdenum to provide enhanced corrosion resistance. They have superior strength and resistance against oxidation, corrosion, and pitting in both acidic and alkaline conditions. Mechanical properties comprise a significant tensile strength of 520-750 MPa, and they come with a yield strength of 205-290 MPa. Owing to exceptional durability coupled with high-temperature resistance, they are specially suited for critical applications in chemical, oil & gas, and power generation industries.
Stainless Steel Weld Neck Flanges are generally made from SS 304, 304L, 316, and 316L, which are austenitic stainless steels containing 18–20% chromium, 8–14% nickel, and, for 316/316L, 2–3% molybdenum. These elements grant exceptional corrosion resistance, especially in acidic and chloride-rich environments. The mechanical properties include a tensile strength ranging from 485–620 MPa and a yield strength of 170–310 MPa, depending on the specific grade. These flanges are highly resistant to thermal expansion, pressure changes, and mechanical stress, making them ideal for demanding, long-term use in harsh conditions.
