Zhengju New Materials Successfully Delivered the UHMWPE Pipe System for the G217 Expressway Tunnel Project
Zhengju New Materials has successfully delivered a complete set of high-performance UHMWPE pipe systems for the G217 Expressway Tunnel Project in Xinjiang. All pipes have been officially produced and transported to the construction site as scheduled. These pipes are specially designed for continuous mud and gravel transportation under extreme high-altitude environments, fully meeting the strict requirements of tunnel construction for impact resistance, wear resistance and rapid on-site installation.
1. Project Overview & Delivery Achievement
The G217 Expressway Tunnel Project is a key transportation infrastructure located in a high-altitude area of Xinjiang. The construction environment is harsh, requiring pipelines to withstand long-term erosion of mud, gravel and low-temperature impact. To meet tight construction schedules, Zhengju New Materials gave full play to its automated UHMWPE production advantages and completed mass production and delivery efficiently.
The delivered UHMWPE pipes cover a full size range from DN50 to DN600, which are widely used in tunnel mud transportation, temporary drainage and gravel slurry conveying. With excellent performance and stable quality, they have become a reliable supporting pipeline solution for the tunnel project.
1.1 Core Product Parameters (UHMWPE Pipe)
The performance of UHMWPE pipes directly determines their service life and conveying efficiency in high-wear and high-impact environments. The core parameters are shown in the table below:
| Core Performance Index | Standard Value | Application Value in Tunnel & Slurry Transportation |
|---|---|---|
| Wear Resistance | 3-5 times that of ordinary steel pipes | Effectively resists long-term erosion of mud and gravel, greatly extending service life |
| Low-temperature Impact Resistance | Excellent at -20°C~80°C | Stable performance in high-altitude low-temperature environments, not easy to crack |
| Chemical Corrosion Resistance | Resistant to acid, alkali, salt and organic media | Suitable for various complex geological water quality and chemical slurry |
| Non-stick & Anti-scaling | Low surface friction, no scaling | Keep smooth flow, reduce blockage and cleaning costs |
| Specification Range | DN50 – DN600 | Meet different flow requirements of tunnel engineering and slurry conveying |
2. Core Advantages of UHMWPE Pipes by Zhengju New Materials
.
Zhengju UHMWPE pipes adopt a special ultra-high molecular weight polyethylene matrix structure, which integrates the advantages of high wear resistance, high toughness and corrosion resistance, making them extremely suitable for tunnel construction and high-wear slurry transportation.
2.1 Ultra-high Wear Resistance
UHMWPE pipe has excellent wear resistance, which is much higher than steel pipe, HDPE pipe and other traditional pipes. It can run stably for a long time under the friction of high-density mud and sharp gravel, greatly reducing pipeline replacement and maintenance costs.
2.2 Excellent Low-temperature Impact Resistance
The product maintains high toughness even in low-temperature and high-altitude environments, with strong resistance to external impact and pressure fluctuation, effectively preventing pipe cracking and damage during construction and operation.
2.3 Light Weight & Easy Installation
UHMWPE pipe is lighter than metal pipe, easy to transport, load and unload. It supports electrofusion welding connection, which realizes fast and reliable on-site installation and greatly improves tunnel construction efficiency.
2.4 Anti-corrosion & Anti-scaling
The pipe has excellent chemical stability, no rust, no scaling, low fluid resistance, ensuring smooth conveying and reducing the risk of pipeline blockage in long-term use.
3. Transportation & On-site Technical Support
Zhengju New Materials cooperates with a professional heavy-duty logistics team to formulate a safe transportation plan for large-diameter pipelines, ensuring that all specifications of products arrive at the G217 tunnel project site safely and on time.
In addition to product supply, the company also dispatched professional on-site engineers to provide full technical support, including electrofusion welding training, pipeline laying guidance and post-installation pressure test support, ensuring the smooth progress of on-site construction.
