High-pressure, high-durability pipeline engineered for mining, industrial, and municipal applications.
⭐Product Description
The multi-layer steel wire wound modified polyethylene wear-resistant composite pipe is a new-generation environmentally friendly pipeline. High-strength steel wires are helically wound around the pipe to form a mesh-structured reinforcement layer, while the inner and outer layers use modified polyethylene as the matrix. These layers are bonded through hot-melt adhesive and formed via continuous extrusion, creating a highly robust composite structure.
⭐ Structure Composition
· Reinforcement Layer: High-strength steel wire mesh wound framework
· Matrix Material: Modified polyethylene (PE) for both inner and outer layers
· Manufacturing Process: Hot-melt adhesive bonding + continuous extrusion molding
⭐ Core Features
Exceptional Wear Resistance
POE-based wear-resistant lining delivers outstanding abrasion performance—8× stronger than UHMWPE, 15× stronger than HDPE, and 100× stronger than steel. Ideal for transporting high-abrasion media and significantly extending pipeline service life.
High Pressure Capacity
Multi-layer steel wire wound reinforcement ensures extreme pressure resistance under demanding working conditions, providing far greater safety margins than single-structure pipes.
Chemical & Corrosion Resistance
Modified PE matrix offers excellent resistance to acids, alkalis, saltwater, and various corrosive media—preventing scaling and corrosion while reducing maintenance needs.
⭐ Advantages
Multi-Layer Composite Structure
Steel wire reinforcement provides high compressive strength, while modified PE enhances durability and environmental resistance.
Reliable, Leak-Proof Jointing
Compatible with butt fusion and electrofusion welding, ensuring permanent, secure, and leak-free connections.
High Flow Efficiency
Smooth inner wall and optimized hydraulic performance deliver 1.25× the flow capacity of steel pipes at the same nominal diameter.
Flexible & Easy Installation
Lightweight per meter and adaptable to complex terrains, offering higher installation efficiency and lower labor requirements.
Long Service Life & Low Lifecycle Cost
Designed for 50+ years of stable operation with minimal maintenance—resulting in significantly lower long-term cost compared with metal pipelines.
