What Are the Key Features of UHMWPE Lined Steel Pipes for Abrasive Slurry Applications?
UHMWPE (Ultra-High Molecular Weight Polyethylene) lined steel pipes are widely used in mining, dredging, and slurry transport due to their exceptional abrasive wear resistance and durability.
UHMWPE (Ultra-High Molecular Weight Polyethylene) lined steel pipes are widely used in mining, dredging, and slurry transport due to their exceptional abrasive wear resistance and durability. Here are the key features of UHMWPE lined steel pipes that make it outstanding at abrasive slurry transport.
Superior Abrasion Resistance
UHMWPE has 15x the abrasion resistance of carbon steel and outperforms other polymers (e.g., HDPE, nylon) in high-wear slurry applications.
Ideal for transporting sand, tailings, ore, and other abrasive solids.
Low Coefficient of Friction
Smooth UHMWPE lining reduces friction losses by up to 50% compared to bare steel pipes, improving flow efficiency and lowering pump energy costs.
Impact Resistance
Compared to HDPE lined steel pipes, UHMWPE lined steel pipe with UHMWPE liner absorbs shock from large, sharp particles without cracking or delamination easily. For real application cases, slurry particle size need to be checked for further confirmation that UHMWPE liner is suitable for such kind of erosive wear caused by slurry particle turbulence inside pipeline.
Corrosion & Chemical Resistance
UHMWPE liner is chemical Inert to most acids, alkalis, and salts, protecting the steel pipe from corrosive slurries (e.g., acidic mine drainage).
Customizable Lining Thickness of UHMWPE liner
Typical thickness: 8–20 mm, tailored to abrasion severity and design wear allowance for specific tailings pipeline case.
Easy Installation & Maintenance on-site
UHMWPE Lining is tight-fit into steel pipe through mechanical methods, the uhmwpe liner can be pulled out when it comes to end of its wear service life, and new UHMWPE liner can be re-lined on-site by professionally trained operator. This can help the steel pipes being re-used at next stage wear service life, reduce cost for buying new steel pipes.

Cost-Effective Long-Term Solution
Higher upfront cost than steel pipeline but lower lifetime cost due to reduced downtime and replacements. Compared to rubber lined steel pipeline and ceramic lined steel pipeline, UHMWPE lined steel pipes cost less at the upfront stage.
