Zhengju New Materials Successfully Delivers Custom Dual-Pipe Network Solution for North China Mining Project
Recently, Zhengju New Materials successfully completed the delivery of the second batch of pipelines for a key transportation project in a mine located in North China. Building upon prior cooperation utilizing high-pressure SRTP (Steel Wire Mesh Skeleton Polyethylene Composite Pipe), the project expanded into a specialized zoning configuration with UHMWPE (Ultra-High Molecular Weight Polyethylene) pipelines to target severe wear sections, securing long-term network operational stability.
Complex Working Conditions Demand Differentiated Piping
The long-distance pipeline network of this North China mining facility features varied geographic terrains and intricate slurry transport environments. Media attributes differ significantly across distinct piping intervals, making it ineffective for a single pipe material to cover the entire grid.
In the initial project stages, Zhengju's SRTP steel wire composite pipeline was deployed for wide-area application. Featuring robust pressure resistance, steel-plastic composition strength, and flexible resistance to soil settlement, SRTP excellently manages the long-distance transmission of clean water, process backwater, and standard low-abrasion fluids throughout the mine.
The Zoning Matching Strategy: SRTP + UHMWPE
To tackle hyper-abrasive slurry conditions in specific mining zones, the project team collaborated with Zhengju engineers to implement a zoning configuration scheme: "SRTP for Conventional High-Pressure Fluid Loops + UHMWPE for Harsh Slurry Sections." The critical tailings and thick mud delivery paths were upgraded to heavy-duty UHMWPE pipes.
| Technical Parameter | SRTP Pipeline (Steel-Plastic) | UHMWPE Pipeline (Ultra-High) |
|---|---|---|
| Core Application | Main high-pressure water & fluid loops | Harsh slurry, tailings, and dredging sections |
| Material Density | Approx. 960 kg/m³ (PE Matrix) + Steel Core | ~940 kg/m³ (Ultra-high raw molecular structure) |
| Abrasion Resistance | Standard industrial grade | Extremely High (4-6x better than carbon steel) |
| Friction Coefficient | 0.009 (Smooth internal PE wall) | 0.005 (Anti-scaling, prevents thick mud clogging) |
| Chemical Corrosion | Excellent acid & alkali resistance | Outstanding resistance to toxic acid mine drainage |
| Maintenance Cycle | Periodic system inspections | Virtually Maintenance-Free (Drastically limits downtime) |
Long-Term ROI: Slashing Operation & Maintenance Costs
While initial component procurement costs vary slightly, the localized addition of UHMWPE pipes delivers substantial long-term economic gains. Its interior surface limits boundary-layer scaling, enabling smooth slurry discharge and completely eliminating pipe-blocking problems.
Furthermore, UHMWPE's specialized impact toughness withstands severe pumping pressure fluctuations and mechanical stress without cracking or exploding. By neutralizing frequent pipe rotations and accidental leakage disruptions, this complementary setup delivers a highly reliable, cost-efficient, and optimized mining pipeline network.

Project Technical Q&A
A: While UHMWPE features incredible wear resistance, a full-region deployment creates over-engineering for simpler process-water transmission sections. Utilizing high-pressure SRTP for broad water lines and isolating UHMWPE to handle severe thick slurry sections strikes the perfect balance between initial capital expenditure and ultimate pipeline reliability.
A: UHMWPE pipes possess a self-lubricating inner surface with a friction coefficient similar to ice. Highly abrasive mine tailings or heavy thick mud cannot adhere to the inner walls. This minimizes pumping head losses, reduces system power expenditure, and eliminates costly pipeline dredging downtimes.
A: Yes. Zhengju New Materials provides fully tailored manufacturing based on practical field demands. We configure SRTP high-pressure variants alongside customized outer diameters (OD) and varying wall thicknesses for UHMWPE to withstand distinct target working pressures.
Looking ahead, Zhengju New Materials remains dedicated to heavy industrial transportation sectors, such as mines, dredging, water conservancy, and power plants. We will continue optimizing our product delivery framework to provide international clients with cost-effective, high-performing pipeline configurations designed for harsh industrial settings.
