Introducing the Anti-static Flame Retardant Colored Steel Wire Reinforced PE Composite Pipe, widely recognized as the SRTP pipe. This innovative pipeline is engineered by skillfully winding high-strength steel wires around a robust polyethylene (PE) core. Departing from traditional carbon black conductivity, our company has pioneered independent research to develop a striking, brightly colored antistatic flame retardant pipeline. This breakthrough innovation marks a significant milestone for standardized mining construction.
Leveraging Donghong's advanced TOP-modify material modification technology, we are ushering in a revolutionary era of anti-static flame retardant safety for plastic pipes.
After 5 years of dedicated research and development by Donghong's elite team of 12 researchers, the groundbreaking TOP-modify material modification technology was born. This technology ensures the pipe maintains its excellent tensile properties while achieving a surface resistance of less than105Ω. The antistatic and flame retardant performance surpasses industry standards, offering unparalleled safety and reliability for mining pipelines.
1. Electrofusion Welding: This advanced technique employs specialized equipment to heat the ends of the pipes and fittings. By melting the material, it creates an exceptionally strong bond that seamlessly fuses the components together.
2. Butt Fusion Welding: In this method, similar to electrofusion welding, the ends of the pipes are heated and then pressed together, producing a seamless and robust joint that ensures high durability and integrity.
3. Flange Connections: Flange connections involve attaching flanges to the pipe ends. These flanges are then securely bolted together with gaskets in between, creating a reliable and tight seal ideal for complex pipeline systems.
4. Mechanical Couplings: This method uses compression fittings or clamps to join pipe sections quickly and efficiently. Mechanical couplings offer a rapid and straightforward solution for connecting pipes, ensuring a dependable and secure fit.
5. Threaded Connections: Certain steel wire reinforced PE composite pipes come with threaded ends. These ends can be easily screwed together with compatible fittings or adapters, providing a convenient and reliable connection option.

Shenhua Shendong Coal Group stands as the cornerstone of Shenhua Group's coal production efforts, boasting 15 mines where the benchmarks for safety, output, technology, and economic metrics have achieved unparalleled domestic and global recognition. As a dedicated long-term strategic partner, Donghong Pipeline proudly handles the construction and ensures impeccable after-sales service for Shenhua Shendong Coal Group's underground pipeline network system project. Over the past 20 years, Donghong's mining pipeline has impressively operated safely across 165,000 kilometers, a distance that could encircle the Earth's equator four times. Collectively, all Donghong pipelines span approximately 398,000 kilometers, a length comparable to the distance between the Earth and the Moon.
1. Corrosion Resistance : The PE (polyethylene) inner layer provides excellent resistance to corrosion, making the pipe suitable for conveying various fluids, including water, chemicals, and hydrocarbons.
2. High Strength : The steel wire reinforcement enhances the pipe's structural integrity, allowing it to withstand high-pressure applications and external loads such as soil and traffic loads.
3. Lightweight : Compared to traditional metal pipes, steel wire reinforced PE composite pipes are lightweight, making them easier to transport, handle, and install, reducing labor and equipment costs.
4. Flexibility : The flexibility of PE materials allows for the pipe to be bent and routed around obstacles without the need for additional fittings, reducing the risk of leaks and minimizing installation time.
5. Longevity : Steel wire reinforced PE composite pipes have a long service life, as they are resistant to environmental factors such as UV radiation, abrasion, and chemical exposure, reducing maintenance requirements and lifecycle costs.
6. Cost-Effectiveness : The combination of durability, lightweight design, and ease of installation results in overall cost savings over the lifetime of the pipeline, making it a cost-effective solution for various applications.
These advantages make steel wire reinforced PE composite pipes a preferred choice for a wide range of industries, including mining, water supply, municipal infrastructure, and industrial applications.
