Our wear-resistant steel wire reinforced composite pipes are meticulously engineered to endure the harshest abrasion and impact scenarios, ensuring unmatched durability and extended service life in the most challenging operating environments. These exceptional pipes blend the formidable strength of steel wire reinforcement with the enduring resilience of advanced composite materials, delivering unwavering and reliable solutions for the conveyance of abrasive fluids or slurries in the most demanding industrial applications.
Boasting a unique construction, this pipe features an intricately integrated steel wire skeleton, seamlessly combined with high-quality composite materials such as high-density polyethylene (HDPE) or polypropylene (PP). This synergy creates an extraordinarily robust and durable pipeline. The embedded steel wire reinforcement significantly fortifies the structural integrity of the pipe, while the advanced composite materials provide outstanding corrosion resistance and superior wear performance, ensuring reliability and longevity.
Our Advantages

After many years of case accumulation, we have summarised the construction experience in various complex operating environments such as mountains, paddy fields, ponds and so on.
1.Electrofusion Welding: This method involves using specialized equipment to heat the pipe ends and fittings, melting the material and allowing them to fuse together.
2.Butt Fusion Welding: Similar to electrofusion welding, butt fusion welding involves heating the pipe ends and then pressing them together to create a seamless joint.
3.Flange Connections: Flange connections utilize flanges attached to the pipe ends, which are then bolted together with gaskets to create a secure seal.
4.Mechanical Couplings: Mechanical couplings are used to join pipe sections together using compression fittings or clamps, providing a quick and easy connection method.
5.Threaded Connections: Some steel wire reinforced PE composite pipes feature threaded ends, allowing them to be screwed together with compatible fittings or adapters
1.Exceptional Wear Resistance: The combination of steel wire reinforcement and wear-resistant composite materials provides outstanding resistance to abrasion, erosion, and impact, ensuring prolonged service life in abrasive environments.
2. High Strength and Durability: The steel wire reinforcement enhances the structural strength and durability of the pipe, allowing it to withstand high pressure and mechanical stress without deformation or failure.
3. Corrosion Resistance: The composite materials used in the pipe construction offer excellent corrosion resistance, making the pipe suitable for conveying corrosive fluids or slurries in chemical processing, mining, and other industries.
4. Lightweight and Easy to Install: Despite their robust construction, wear-resistant steel wire reinforced composite pipes are lightweight and easy to handle, transport, and install, reducing labor and installation costs.
5. Flexibility and Versatility: The flexibility of the composite materials allows the pipe to bend and conform to the terrain, making it suitable for use in various applications, including mining, dredging, wastewater treatment, and industrial processing.
6. Smooth Inner Surface: The smooth inner surface of the pipe minimizes friction losses and reduces the risk of clogging or scaling, optimizing the efficiency of fluid transportation systems.
7. Long Service Life: Due to their superior wear resistance and durability, wear-resistant steel wire reinforced composite pipes offer a longer service life compared to traditional materials like steel or concrete, resulting in reduced maintenance and replacement costs over time.
