Composite pipe--Wear-resistant Wear-resistant HDPE pipe

Polyethylene raw material -- Coal mine polyethylene material belongs to Donghong's own patented product - flame retardant and antistatic CNT-modified material, which is wrapped on both internal and external surfaces so that the color of the paint application is maintained permanently. This composite polyethylene material ensures that the flame retardant grade and antistatic grade of the pipe exceeds MT181grade and MT558.1 grade, and improves the mechanical properties of the material.

High Durable Steel Wire --  Adopting coopered steel wire under the requirement of GB/T 14450, achieve the pressure strength ≥2050Mpa.

Adhesive resin -- adopting Donghong's self-developed patented resin products, it excels in strong adhesion and process adaptability.

Connection Methed

1.Electrofusion Welding: This sophisticated technique involves using specialized equipment to heat the pipe ends and fittings until they melt and fuse together, ensuring a seamless and robust connection.

2. Butt Fusion Welding: Mirroring the process of electrofusion, butt fusion welding heats the pipe ends and presses them together, creating a seamless and durable joint that stands the test of time.
3. Flange Connections: Employing robust flanges attached to the pipe ends, these connections are bolted together with gaskets, forming a secure and reliable seal for various applications.
4. Mechanical Couplings: Utilizing compression fittings or clamps, mechanical couplings offer a quick and efficient method for joining pipe sections, ensuring ease of installation and strong connections.
5. Threaded Connections: Featuring threaded ends, some steel wire reinforced PE composite pipes can be easily screwed together with compatible fittings or adapters, offering versatile and reliable connection options
