Harsh Flanges, located in Mumbai, India, has made a name for itself as a leading manufacturer and supplier of Incoloy Orifice Flanges, which are essential for accurate flow measurement and control in piping systems. Made from top-notch Incoloy alloys like Incoloy 800 and 825, these flanges are built to withstand high temperatures, oxidation, and corrosion. They adhere to strict standards such as ASME and ASTM, ensuring reliable sealing and precise metering in critical industrial settings. At Harsh Flanges, we are dedicated to providing durable, precision-engineered orifice flanges tailored for the chemical, power generation, and petrochemical industries.
Incoloy Orifice Flanges are made from nickel-iron-chromium alloys, mainly Incoloy 800 or 825. Their typical composition features 30–46% Nickel, 19–23% Chromium, along with Iron, Molybdenum, and Carbon to boost strength and corrosion resistance. These flanges exhibit tensile strengths between 520–690 MPa and yield strengths from 205–350 MPa. Their exceptional resistance to oxidation, sulfidation, and stress-corrosion cracking at high temperatures guarantees longevity and performance in tough environments. The mechanical strength and corrosion resistance of Incoloy alloys make these flanges perfect for precise flow measurement tasks.
Harsh Flanges, a premier supplier in Mumbai, India, specializes in high-quality Incoloy Orifice Flanges, valued for their exceptional durability, corrosion resistance, precise engineering, and suitability across diverse industrial applications.
