High-wear And Corrosive Applications
Slurry pipes are designed for conveying abrasive and corrosive materials with high durability and minimal maintenance, ensuring efficiency in heavy-duty applications.
Slurry Pipes are specialized pipeline systems engineered to transport abrasive, viscous, or corrosive slurries across diverse industries like mining, dredging, power generation, and mineral processing. These pipes are built to endure internal wear, external stress, and chemical attacks, ensuring reliable long-term operation.
The interior lining materials of slurry pipes, such as alumina ceramic, cast basalt, UHMWPE, or rubber, are carefully selected to guarantee high performance in harsh environments. The outer shell, usually crafted from carbon steel or alloy steel, offers mechanical strength and pressure resistance.
Slurry pipes come in various configurations including straight sections, elbows, reducers, tees, and expansion joints. They can be custom-designed to fit specific system layouts. For convenient installation and maintenance, common end connection types include flanges, quick couplings, and grooved joints.
Whether used in pumping stations, pipeline loops, or tailings disposal systems, slurry pipes play a crucial role in reducing downtime, minimizing maintenance costs, and extending the lifespan of equipment.

Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.
With a molecular weight typically between 3.5 and 9.2 million g/mol, UHMWPE exhibits superior wear resistance, impact strength, and chemical stability, far exceeding conventional polyethylene or metal pipes in durability and performance.
Offers 15× the wear resistance of steel and 4× that of stainless steel, ideal for high-abrasion conditions.
Weighs 8× less than steel (specific gravity 0.93–0.95), lowering transportation and installation costs.
Excellent resistance to acids, alkalis, and organic solvents with zero corrosion in chemical environments.
The specifications of Ultra-High Molecular Weight Polyethylene (UHMWPE) pipes can vary based on the manufacturer, application, and specific requirements. However, here are some common specifications that are often associated with UHMWPE pipes:
