Alloy Steel ASTM A182 F22 Flanges from iSteel India join pipe sections, valves, and equipment in piping systems that run hot and under pressure at the same time. Manufactured in Mumbai, these flanges are forged from a 2.25% chromium, 1% molybdenum alloy steel produced to ASTM A182 and ASME SA182. That chemistry gives F22 properties carbon steel cannot match at elevated temperature: strength that holds under sustained load, an oxide layer that resists scaling, creep resistance that stops the flange from slowly deforming, and weld characteristics suited to field fabrication. Refineries and power plants specify F22 because it keeps performing where lower grades start to fail. We forge these flanges across the full range of pressure classes and flange types that critical piping systems demand.
Our F22 flange range includes weld neck, slip-on, blind, socket weld, threaded, lap joint, spectacle blind, and orifice flanges. Manufacturing follows ASTM A182 and ASME SA182 for material, ASME B16.5 for sizes up to 24 inches, ASME B16.47 for larger diameters, and MSS SP-44 where applicable. Sizes span the standard NPS range, with pressure classes from 150# to 2500# available depending on flange type, and facing options include raised face, ring type joint, and flat face to match the gasket and bolting arrangement specified. F22's chromium-molybdenum composition holds mechanical strength at temperatures where carbon steel would soften, and its resistance to hydrogen attack makes it a standard choice in refinery hydroprocessing units. These flanges go into refineries, power plants, boiler systems, petrochemical plants, oil and gas installations, and chemical processing units where line temperature rules out lower alloy grades. We supply F22 flanges across Mumbai and India, and export them to project sites overseas.
