Flange

Flanges are common disc-shaped parts used in pipeline engineering. The shape of a flange is typically circular. The main function of a flange is to connect pipes while maintaining a sealed state, and it also facilitates easy disassembly and inspection. In pipeline engineering, flanges are primarily used to connect pipes, valves, pumps, and equipment, ensuring that fluids can pass through smoothly and safely.

Product advantages

1. Flanges, as the common disc-shaped pipe components, are widely used in various pipeline systems. They are designed to be simple and versatile, easily meeting a variety of pipe connection needs.
2. Made from high-quality steel, they ensure that the flanges have wonderful pressure resistance and impact resistance, allowing for long-term stable operation in harsh environments and reducing maintenance costs.
3. There is a gasket between the two flanges, which effectively enhances the sealing performance of the connection, preventing leakage of liquids or gases, and ensuring the normal operation of the pipeline system.
4. The precise hole positioning design on the flange plate makes the installation process simpler, improves work efficiency, and reduces installation costs.
5. As a professional flange manufacturer, we offer direct sales services, reducing intermediate links and lowering costs, making our flange products more cost-effective and creating greater value for our customers.
