HDPE pipe fittings – Stub End / Flange Adaptor – are a key component commonly used in pipe connection systems, typically used in conjunction with backing rings.These flange adapters are manufactured using an integral injection molding process, resulting in a dense structure and stable performance. They are widely used in water supply and drainage, irrigation, water treatment, and industrial fluid transport.
Main Features of HDPE Flanges:
1. One-piece injection molding, high strength: Utilizing a one-piece injection molding process, there are no welds or splices. The uniform molecular structure results in excellent pressure resistance and impact resistance, ensuring safer and more reliable long-term operation.
2. Excellent corrosion resistance: HDPE material exhibits good resistance to acids, alkalis, salts, and various chemical media, making it suitable for complex working environments.
3. Good sealing performance: When used with steel or plastic slip-on flanges and rubber gaskets, it achieves efficient sealing and strong leak-proof capability.
4. Lightweight and easy to install: Lighter than metal fittings, reducing transportation and construction costs, and allowing for quick pipe connection.
5. Long service life: Anti-aging and wear-resistant, with a service life of over 50 years under normal operating conditions.
6. High dimensional accuracy: Injection mold production ensures uniform interface dimensions, adapting to international standard flanges (such as ANSI, DIN, ISO, etc.).
Main Applications of HDPE Flanges:
1. Pipe and Valve Connections: Used for flange connections between HDPE pipes and valves, pumps, flow meters, and other equipment.
2. Detachable Interfaces for Pipe Systems: Facilitates future maintenance, repair, and equipment replacement.
3. Transition Connections Between Pipes of Different Materials: Enables reliable connections between HDPE pipes and steel pipes, PVC pipes, or pipes of other materials.
4. Water Supply, Drainage, and Irrigation Systems: A common connection method in urban water supply, agricultural sprinkler and drip irrigation projects.
5. Industrial Fluid Transport Systems: Widely used in chemical, water treatment, power, and mining industries.
