PN2.5 UHMWPE Lined Steel Pipe for Mining Slurry
PN2.5 UHMWPE Lined Steel Pipe for Mining Slurry | DN50-DN1000 Abrasion Resistant Pipeline
Our premium PN2.5 UHMWPE lined steel pipe represents the ultimate solution for heavy-duty industrial fluid transportation, specifically engineered for harsh mining slurry, tailings disposal, and mineral processing lines. By combining the mechanical strength of a seamless carbon steel outer pipe with the exceptional wear resistance of a virgin PE1000 ultra-high molecular weight polyethylene (UHMWPE) inner lining, this composite pipeline eliminates the risk of premature wear and structural failure. Available in full nominal diameters from DN50 to DN1000, it delivers a maintenance-free service life that vastly outperforms traditional steel or rubber-lined alternatives.
Key Features & Technical Advantages
• Extreme Abrasion Resistance: The ultra-high molecular weight (PE1000) lining offers a wear resistance rate 4 to 7 times higher than carbon steel (Q235), making it perfect for abrasive ore slurries.
• Advanced Mechanical Strength: Capable of handling high-pressure operations up to PN2.5 (2.0Mpa / 20Bar / 290PSI), heavily fortified by the external heavy-wall steel casing.
• Anti-Scaling & Ultra-Low Friction: With a friction coefficient of just 0.07-0.11, the self-lubricating inner surface prevents mineral scaling, minimizes pressure drop, and significantly reduces pumping energy costs.
• Reliable Flanged Connections: Features a secure stub end with loose flanges or steel backing rings, ensuring easy tool-free installation and 100% leak-proof performance under vibration.
