Ismail Flanges is a top Indonesian manufacturer and supplier of Alloy 20 Orifice Flanges located in Jakarta, Indonesia, and it offers high-quality flanges for precise flow measurement and corrosion resistance. The flanges are manufactured from Alloy 20, a nickel-iron-chromium alloy, and are designed to operate in severe chemical environments, particularly those with sulfuric acid. Ismail Flanges serves diverse industries such as chemical processing, pharmaceuticals, and petrochemicals through the supply of robust and dimensionally correct orifice flanges. Equipped with the latest manufacturing technologies and sticking to international standards, the company provides consistent and durable products for high-demanding flow control systems.
Alloy 20 Orifice Flanges consist of nickel (32–38%), chromium (19–21%), iron, copper (3–4%), and molybdenum (2–3%). This composition provides them with excellent resistance to sulfuric acid, chloride-stress corrosion cracking, and pitting. Mechanically, they provide a minimum tensile strength of 551 MPa and a yield strength of 241 MPa, along with good elongation and toughness. These characteristics, when paired with corrosion resistance, make them suitable for harsh chemical environments. The orifice design enables the measurement of flow rate with accuracy through the production of a pressure drop, which is very important in process control systems.

Ismail Flanges, a leading supplier in Indonesia, Jakarta, offers an extensive selection of Alloy 20 Orifice Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.
Alloy 20 Orifice Flanges find extensive use within industries where precise fluid flow measurement is essential under corrosive environments. Typical applications comprise chemical plants, pharmaceutical production, food processing, and petrochemical plants. These flanges are mounted in pipes to gauge the liquid flow or gas flow rate through a pressure difference across an orifice plate. Due to their corrosion resistance, they are best used to carry aggressive materials like sulfuric acid, nitric acid, and chlorides. They provide both process efficiency and safety in applications where accurate control and durability over a long period of time are required.
