PN2.5 UHMWPE steel pipe, suitable for mining slurry transportation
PN2.5 UHMWPE Lined Steel Pipe for Mining Slurry | Abrasion-Resistant Pipeline, DN50-DN1000
Our PN2.5 UHMWPE lined steel pipe represents the ultimate engineering solution for highly abrasive and high-pressure fluid transportation. By combining the rigid mechanical strength of a carbon steel outer pipe with the exceptional wear resistance of a virgin ultra-high molecular weight polyethylene (UHMWPE) inner lining, this composite pipeline eliminates premature structural failures. Engineered specifically for harsh mining slurry, tailings disposal, mineral processing, and dredging projects, it offers an uncompromised full nominal diameter range from DN50 to DN1000 to maximize flow efficiency.
Key Features & Technical Advantages
• Superior Abrasion Resistance: The PE1000 UHMWPE inner lining provides a wear resistance rate 4 to 7 times higher than standard carbon steel, ideal for ore slurry.
• High Pressure Sustainability: Rated at PN2.5 (up to 2.5 Mpa / 25 Bar), fortified by the heavy-wall steel outer casing to withstand severe water hammer impacts.
• Anti-Scaling & Smooth Flow: Extremely low friction coefficient (0.07-0.11) ensures a self-lubricating surface, preventing mineral scaling and reducing pumping power costs.
• Reliable Flanged Connections: Equipped with secure stub ends and loose steel backing rings or flanges, ensuring 100% leak-proof and easy on-site installation.
