Flanges are essential components in piping systems for connection, sealing, and equipment docking. They are widely used in HDPE, PVC, steel pipes, and Industrial Pipeline Solutions. Through bolt tightening and gasket mating, flanges provide a stable, reliable, and detachable pipe connection.
Our flange product range includes HDPE flange systems, steel flanges, and PVC flanges, and we offer complete gasket and bolt sets suitable for various applications such as municipal engineering, agricultural irrigation, mining transportation, and industrial fluid transportation.
A flange is a standardized pipe fitting used to connect pipes, valves, pumps, and other equipment. It achieves a high-strength, sealed connection through bolt fastening and the use of gaskets.
The main characteristics of flange connections are their high degree of disassembly, facilitating future maintenance and system expansion. They are also suitable for transition connections between pipes of different materials, making them an indispensable component in modern piping engineering.
HDPE flanges are mainly used for equipment and pipe connections in HDPE piping systems, typically used in conjunction with heat fusion couplings.

2. Why are flanges needed for HDPE pipes?
Flange connections are used for equipment interfaces, pump station connections, and locations requiring disassembly for maintenance.
3. What is the difference between flange connections and welded connections?
Flange connections are detachable and suitable for equipment connections; welded connections are permanent seals.
4. Can flanges be reused?
The flange body is reusable, but it is recommended to replace the sealing gaskets.
5. Are standard sizes available?
Yes, we offer a variety of sizes conforming to international standards.
6. Do you support custom flanges?
Yes, we can customize sizes and materials according to project requirements.
7. Are flanges suitable for high-pressure systems?
Steel flanges are suitable for high-pressure industrial systems; HDPE flanges are suitable for medium and low-pressure systems.
8. Are bolts and gaskets provided?
Yes, a complete set of bolts, nuts, and gaskets is provided.
9. How to choose the flange material?
Steel, HDPE, or PVC flanges are available based on the pressure rating and operating environment.
10. Is export packaging supported?
Standard export packaging and project-specific packaging are supported.
