Introducing the Anti-static Flame Retardant Colored Steel Wire Reinforced PE Composite Pipe, also known as SRTP Pipe-a revolution in pipeline technology. Carefully engineered by winding high-strength steel wires around a durable polyethylene (PE) core, this pipe breaks away from traditional carbon black conductivity. Our independently developed, cutting-edge color antistatic flame retardant technology not only enhances safety but also offers a vibrant appearance, setting a new benchmark for standardized mine construction.
Utilizing Donghong's pioneering TOP-modify material modification technology, we herald a new era of anti-static, flame retardant safety in plastic piping systems.
After 5 years of dedicated research, Donghong's team of 12 experts successfully developed the TOP-modify material modification technology. This innovation maintains the pipe's tensile strength while achieving a surface resistance of less than105Ω. This superior antistatic and flame retardant performance exceeds industry standards, ensuring unparalleled safety and reliability in mining pipeline operations.
1. Electrofusion Welding: This advanced technique employs state-of-the-art equipment to heat the ends of the pipe and fittings, causing the material to melt and seamlessly fuse together, ensuring a robust and durable connection.
2. Butt Fusion Welding: Butt fusion welding is akin to electrofusion welding, wherein the pipe ends are heated and pressed together, forming a seamless and resilient joint that guarantees longevity and reliability.
3. Flange Connections: Flange connections involve attaching flanges to the pipe ends, which are then bolted together with precision-engineered gaskets, creating a secure seal that withstands high pressure and ensures leak-free performance.
4. Mechanical Couplings: Mechanical couplings provide a swift and straightforward connection method by using compression fittings or clamps to join pipe sections, offering both convenience and a reliable, leak-proof connection.
5. Threaded Connections: Some steel wire reinforced PE composite pipes are equipped with threaded ends, enabling them to be effortlessly screwed together with compatible fittings or adapters, ensuring a tight, secure, and easily adjustable connection.

Shenhua Shendong Coal Group stands at the pinnacle of coal production within the Shenhua Group, boasting 15 highly efficient mines. The group excels in safety, production, technology, and economic performance, meeting both domestic and international elite standards. As a trusted and long-term strategic ally, Donghong Pipeline plays a crucial role in constructing and maintaining Shenhua Shendong's underground pipeline network system. Over the past 20 years, Donghong's mining pipelines have safely transported resources across 165,000 kilometers-equivalent to circling the Earth's equator four times. In total, Donghong pipelines span approximately 398,000 kilometers, symbolically connecting the Earth to the Moon.
1. Exceptional Corrosion Resistance : The inner layer, crafted from premium PE (polyethylene), offers superb resistance to corrosion. This makes our pipes ideal for transporting a variety of fluids, whether water, chemicals, or hydrocarbons.
2. Superior High Strength : The steel wire reinforcement built into our pipes significantly boosts their structural integrity. This allows them to endure high-pressure applications and withstand external loads, including those from soil and vehicular traffic.
3. Remarkably Lightweight : Unlike traditional metal pipes, our steel wire reinforced PE composite pipes are notably lightweight. This facilitates easier transport, handling, and installation, leading to reduced labor and equipment expenses.
4. Exceptional Flexibility : The inherent flexibility of PE materials allows our pipes to bend and navigate around obstacles effortlessly, eliminating the need for additional fittings. This minimizes leak risks and significantly cuts down on installation time.
5. Extended Longevity : With resistance to environmental challenges such as UV radiation, abrasion, and chemical exposure, our steel wire reinforced PE composite pipes promise a long service life. This reduces maintenance needs and overall lifecycle costs.
6. Exceptional Cost-Effectiveness : Combining durability, a lightweight design, and ease of installation, our pipes deliver significant cost savings throughout their lifecycle. This makes them a highly cost-effective solution for various applications.
These outstanding advantages make our steel wire reinforced PE composite pipes the preferred choice across numerous industries, including mining, water supply, municipal infrastructure, and industrial sectors.
