Multi-layer Steel Wire Wound Modified Polyethylene Composite Pipe (for Hot & Cold Water)

A high-performance environmental-friendly pressure pipe combining steel-strength reinforcement with the hygiene, flexibility, and corrosion resistance of polyethylene.

⭐Product Description

This composite pipe is constructed with a high-strength steel wire mesh reinforcement and modified polyethylene inner and outer layers, bonded through hot-melt adhesive and continuously extruded. The design integrates the excellent pressure-bearing capability of steel pipes with the sanitary, flexible, and corrosion-resistant characteristics of PE pipes, resulting in a durable, reliable, and easy-to-install piping solution.

⭐ Key Features

· Hygienic & Non-toxic – suitable for potable hot and cold water systems

· Leak-free Performance – electrofusion welding fuses pipe and fittings into a single homogeneous system

· Strong Resistance to Ground Movement – absorbs stress from settlement, displacement, and end loads

· Corrosion & Scaling Resistant – no need for concrete bedding; minimal maintenance

· Superior Hydraulic Performance – smooth inner wall ensures low friction and stable flow

· Seismic Flexibility – excellent shock absorption under vibration or seismic conditions

· Outstanding RCP & SCG Resistance – prevents rapid crack propagation and slow crack growth

· Long Service Life – designed for more than 50 years under high temperature and pressure

⭐ Eight Major Advantages

1. Long-term Thermal Stability – service life >50 years under high temperature and internal pressure

2. Excellent Insulation – thermal conductivity 0.42 W/(m·K) (~1% of steel) ensures minimal heat loss

3. Higher Flow Capacity – inner roughness of 0.01, >1.25× the flow of steel pipes

4. High Installation Efficiency – lightweight per meter; electrofusion connections for fast assembly

5. Superior Corrosion Resistance – no rust, no scaling, no blockage; protects water quality

6. Lower Overall Cost – composite structure saves >50% material cost vs traditional heat-resistant pipes

7. Easy Maintenance – flexible enough for flattening recovery after depressurization

8. Significant Social Benefits – energy-saving, water-saving, and improved system safety
