Electrofusion HDPE fittings are designed to join polyethylene pipes by using electric current to heat and melt the fitting material, creating a permanent fusion bond. This electrofusion process ensures that the joint strength is equal to or even higher than the pipe itself, providing a highly secure and reliable connection.
HDPE stub flanges are pipe connection accessories used to join different pipeline systems. By combining flanges, bolts, and nuts, they enable secure connections between HDPE pipes and other materials such as steel pipes, valves, and pumps. They are commonly used with HDPE corrugated pipes as well. The use of HDPE stub flanges simplifies installation, improves connection reliability, and enhances the overall performance of the pipeline system.
Flanged Connection Solution: HDPE stub flanges enable reliable flange-to-flange pipe connections, ensuring stable integration within pipeline systems.
Excellent Material Performance: Utilizing HDPE’s outstanding corrosion resistance, abrasion resistance, and thermal stability, they are widely applied across various industrial fields.
Suitable for High-Pressure Systems: Capable of withstanding higher operating pressures, making them ideal for circulating water transmission and similar demanding applications.
Easy and Secure Installation: Simple connection method with strong joint performance, ensuring safe and efficient assembly.
Flexible Compatibility: Can be adapted to different pipe diameters, providing convenient connection solutions for complex pipeline layouts.
Long Service Life & Impact Resistance: Excellent durability and shock resistance ensure reliable long-term performance in circulating water systems and other continuous operation environments.

During installation, HDPE stub flanges are used to connect two pipeline sections by aligning the pipes and securing them with steel flanges, bolts, and nuts. This method provides a strong and stable mechanical connection, and sealing performance can be further enhanced by adding gaskets to effectively prevent leakage.
In addition, HDPE fusion technologies such as electrofusion and butt fusion further improve joint reliability and connection quality, ensuring long-term safe and stable operation of the pipeline system.
