Ismail Flanges, located in Jakarta, Indonesia, is a reliable manufacturer and supplier of high-performance industrial flanges tailored for pressure systems and high-temperature applications. Our P250GH Flanges are crafted from EN 10222-2 certified pressure vessel steel, making them perfect for seamless integration into boiler systems, pressure vessels, and heat exchangers. These flanges boast exceptional weldability, strength, and resistance to high-temperature stress. At Ismail Flanges, we ensure that every P250GH flange is produced to meet international standards like EN 1092-1, guaranteeing dependable performance for power plants, refineries, petrochemical facilities, and high-pressure piping systems across various industrial sectors.
P250GH Flanges are constructed from non-alloy quality steel, featuring a typical composition of carbon (≤0.20%), manganese (0.80–1.50%), silicon (≤0.40%), phosphorus (≤0.025%), and sulfur (≤0.015%). These flanges provide a minimum yield strength of 250 MPa, tensile strength ranging from 410 to 530 MPa, and an elongation of ≥24%, ensuring excellent formability and mechanical integrity. P250GH also demonstrates reliable creep resistance, impact strength, and weldability, making it suitable for high-pressure and high-temperature conditions in the energy and chemical processing industries.
Ismail Flanges, a leading supplier in Indonesia, Jakarta, offers an extensive selection of P250gh Flange, 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.
