A well-known producer and supplier of stainless steel orifice flanges, Harsh Flanges is based in Mumbai, India, and provides high-performance solutions for accurate flow measurement and control. Our flanges are extensively utilised in industries that demand precise fluid regulation and are designed to satisfy international standards. Our orifice flanges, which are made from high-quality stainless steel, guarantee durability, resistance to corrosion, and a precise fit with orifice plates and meters. Harsh Flanges provides dependable products that are suited to high-pressure systems and demanding process applications to customers worldwide, with a strong emphasis on quality and customisation.
304, 304L, 316, and 316L grades of stainless steel orifice flanges are frequently produced. These grades contain 18–20% chromium and 8–14% nickel, with molybdenum (in 316 variants) added to improve resistance to pitting and crevice corrosion. These flanges have outstanding ductility and impact resistance, as well as tensile and yield strengths of 485–620 MPa and 170–310 MPa, respectively. They are appropriate for accurate and dependable flow control in demanding operating environments because they are strong under high pressure and temperature conditions and have good weldability and machinability.

The main application for stainless steel orifice flanges is in flow measurement systems that compute flow rates by measuring the pressure drop across an orifice plate. They are extensively used in the petrochemical, water treatment, power generation, chemical processing, and oil and gas sectors. For precise fluid flow monitoring in liquid and gas pipelines, these flanges are perfect for use with orifice meters, transmitters and flow nozzles. Their precise design helps to maintain flow efficiency and measurement accuracy in high-pressure piping systems, and their resistance to corrosion makes them appropriate for harsh and corrosive environments.
