PLATE FLANGE

Product Overview Plate flanges, also known as flat flanges, are essential piping components used to connect pipes, valves, pumps, and other equipment in industrial systems. They feature a flat disc structure with bolt holes around the perimeter, enabling easy assembly and disassembly through bolted connections. Our plate flanges are available in multiple types, materials, and specifications, including standard models and custom designs tailored to your specific needs.SS400 14inches 126J 5K-B.jpg Key Specifications Category Details Product Types Slip on plate flange, Blind plate flange, Flat plate flange, Weld neck plate flange, Lap joint plate flange Materials Carbon steel (A36, Q235B, Q345B), Stainless steel (304, 316L, 321), Alloy steel (16Mn, 15CrMo), Duplex steel (2205, 2507) International Standards ANSI B16.5, ASME B16.47, DIN 2527, EN 1092-1, JIS B2220, GB/T 9119 Pressure Class Class 150, 300, 600, 900; PN10, PN16, PN25, PN40, PN63 Size Range DN15 - DN2000 (1/2" - 80") Sealing Face Type RF (Raised Face), FF (Flat Face), RTJ (Ring Type Joint), MFM (Male-Female Face) Manufacturing Process Forging, CNC precision machining, Heat treatment (quenching & tempering), Sandblasting, Anti-corrosion coating Quality Certification ISO 9001:2015, CE, API 6A, RoHS, REACH Core Product Advantages Exceptional Durability: Made from high-purity raw materials with strict chemical composition testing, our plate flanges exhibit excellent corrosion resistance, high-temperature tolerance (-40℃ to 600℃), and strong pressure-bearing capacity. The forged structure enhances material density, reducing the risk of cracks and leaks in harsh working conditions. Precision & Compatibility: Adopting advanced CNC machining centers, the dimensional tolerance of our flanges is controlled within ±0.02mm, ensuring a perfect fit with global piping systems. All products comply with international standards, eliminating compatibility issues for cross-border projects. Reliable Sealing Performance: The optimized sealing face design with Ra 1.6-3.2 surface finish ensures tight sealing even under high pressure and vibration. This significantly reduces operational risks in oil, gas, and chemical pipelines, minimizing maintenance costs. Flexible Customization: We support customizations of size, material, pressure class, and surface treatment according to your project drawings or samples. Whether it's a small-batch special specification or a large-scale customized order, we can meet your needs efficiently. Cost-Effective Supply: As a direct factory, we cut out middlemen to offer competitive wholesale prices. We maintain a large inventory of standard flanges, ensuring fast delivery (7-15 working days for stock items; 20-30 working days for custom orders) to avoid project delays. Eco-Friendly Production: Our production processes adopt energy-saving equipment and recyclable materials, complying with global environmental standards. The anti-corrosion coating is non-toxic and pollution-free, helping you achieve sustainable development goals. Application Scenarios Our plate flanges are widely used in various industrial fields due to their versatile performance: Oil & Gas Industry: Pipeline systems for exploration, extraction, and transportation Chemical & Petrochemical Industry: Reactors, storage tanks, and medium transmission pipelines Power Generation: Thermal power plants, nuclear power plants, and renewable energy systems Water Treatment: Municipal water supply, sewage treatment, and desalination projects Marine & Shipbuilding: Ship piping systems and offshore platform equipment HVAC & Boiler Systems: Heating, ventilation, and boiler connection pipelines
