The Steel-Wire Composite HDPE Water Pipe is an innovative pipeline system that merges the flexibility of high-density polyethylene (HDPE) with the structural rigidity of steel-wire reinforcement. Crafted to overcome the shortcomings of traditional pipes in demanding water transport scenarios, this composite solution delivers a harmonious mix of durability, adaptability, and safety. Unlike standalone plastic or metal pipes, the integrated steel-wire layer boosts pressure resistance, while the HDPE casing ensures protection against corrosion and wear. Whether for industrial, municipal, or residential projects, this pipe emerges as a trusted choice for consistent, long-term water conveyance.
| Performance indicators | Unit | Typical values/requirements | Explanation and Standards |
| Longitudinal retraction rate | % | ≤3 | It reflects the thermal stability of the pipe material, and the smaller the value, the better |
| Short-term hydrostatic strength | - | No cracking, no leakage | Core quality indicators. Tests were conducted under different temperatures, times and ring stresses, for example: 80℃, 4.8MPa, 165 hours without failure |
| Blasting pressure | MPa | ≥ 3 × PN | The maximum instantaneous pressure that a pipe can withstand is a manifestation of its safety factor |
| Peel strength | N/cm | ≥100 | Key indicators. The strength of the bond between the steel wire mesh and the inner and outer layers of PE directly affects the composite effect and pressure-bearing capacity |
| Deflection degree | % | ≥0.3 | Measure the flexibility and resistance to bending deformation of the pipe material |
| Oxidation induction time (OIT) | min | ≥20 | It reflects the thermal oxidation resistance of PE raw materials. The larger the value, the better the aging resistance |
| Hygienic performance | - | GB/T 17219 | When used for transporting drinking water, it needs to obtain a hygiene permit and test indicators such as heavy metals and evaporation residues |
The embedded steel-wire reinforcement is the cornerstone of the pipe’s exceptional durability. It enhances the pipe’s ability to withstand extreme internal and external pressures, making it ideal for high-demand water systems. Unlike brittle plastic pipes or heavy steel alternatives, this composite design resists deformation and collapse, ensuring reliable performance in challenging installation conditions.
The HDPE outer and inner layers provide robust defense against corrosion, rust, and chemical degradation. Unlike metal pipes that deteriorate when exposed to acidic or alkaline water, the Steel-Wire Composite HDPE Water Pipe maintains integrity even with water of varying chemical compositions. This resistance eliminates the need for frequent anti-corrosion treatments, cutting down long-term maintenance efforts.
A key benefit of this composite water pipe is its unique balance of flexibility and stability. It adapts to uneven terrain, minor ground settlements, and curved installation paths without cracking or leaking. This flexibility simplifies underground laying, reduces the number of joints, and strengthens the overall reliability of the pipeline system.
Seamless HDPE layers and secure connection methods (such as hot-melt welding) ensure a leak-proof water pipe system. This prevents water waste and contamination, making it suitable for potable water distribution. Additionally, HDPE is a non-toxic, odorless material that avoids leaching harmful substances, guaranteeing the safety of drinking water supplies.
Perfect for urban infrastructure, the pipe efficiently transports clean water to homes and businesses, while handling wastewater drainage. Its corrosion resistance and durability make it a long-lasting solution for municipal projects.
In factories, power plants, and manufacturing facilities, the high-strength HDPE pipe manages industrial water, cooling water, and process water. It withstands the high pressure and chemical exposure common in industrial settings.
Suitable for trenchless technologies like horizontal directional drilling, the pipe’s flexibility and strength enable easy installation without extensive excavation, minimizing disruption to surrounding areas.
Thanks to its hygienic properties and leak-proof design, the pipe is widely used in drinking water systems, ensuring safe and reliable water supply to communities.
The pipe features a core of steel-wire reinforcement encased in high-quality HDPE, chosen for its durability and chemical stability. The HDPE grade offers resistance to UV radiation, aging, and mechanical wear.
The steel-wire layer is evenly distributed for uniform strength, while the HDPE layers are extruded to form a smooth inner surface that reduces flow resistance. The composite structure balances rigidity and flexibility for optimal performance.
Compatible with hot-melt butt welding and electrofusion connection, the pipe creates strong, seamless joints that match the pipe’s inherent strength. These connections eliminate leakage risks and enhance system integrity.
Typically available in black with color-coded marking lines, the pipe is easy to identify on construction sites, simplifying installation and maintenance workflows.
Yes, the pipe uses food-grade HDPE material that is non-toxic and hygienic. It meets international standards for potable water conveyance, ensuring safe drinking water supply.
