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.

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.
