ASTM A182 F91 Flanges Exporter in Indonesia are high-quality flanges made from alloy steel grade F91, specifically designed for high-temperature and high-pressure applications. These flanges are essential components in various piping systems, providing reliable connections. Manufactured and exported by Ferro Fittings and Alloys based in Mumbai, India, these flanges meet stringent industry standards, ensuring durability and performance in demanding environments.
These flanges comply with the ASTM A182 standard, which specifies forged or rolled alloy steel pipe flanges for high-temperature service. Available sizes range from DN 15 to DN 600 (NPS ½ to NPS 24), pressure ratings from Class 150 to Class 2500, and temperature tolerances that can reach up to 600°C (1112°F). The flanges can be equipped with various end connections, including weld neck, slip-on, blind, and socket weld types, making them versatile for different applications.
Industries such as Oil & Gas, Petrochemical, Chemical, Power Generation, Pharmaceutical, Shipbuilding, and Water Treatment extensively utilize these flanges. They are commonly employed in projects across multiple countries, including the UAE, Saudi Arabia, and Qatar, particularly in Engineering, Procurement, and Construction (EPC) and Lump Sum Turnkey (LSTK) projects. Their reliability makes them a preferred choice for maintenance and operational needs in critical infrastructure.
Our commitment to quality is underscored by our ISO 9001:2015 certification and the availability of EN 10204 3.1 / 3.2 Mill Test Certificates. Each flange undergoes rigorous in-house testing, including PMI, Hydrostatic, Hardness, Impact (Charpy), Ultrasonic Testing (UT), and Liquid Penetrant Testing (LPT) to ensure compliance with NACE MR 0175 for sour service applications.
