Abrasion Elite · Slurry Duty
UHMWPE Wear Pipe
Ultra-high molecular weight PE — up to 8× the wear life of carbon steel.
For the toughest slurry service — iron concentrate, coal, tailings, silica sand — UHMWPE wear pipe outlasts every conventional alternative. Heartwork supplies UHMWPE line pipe in flanged, socket-welded and rubber-lined assemblies for the most abrasive fluid systems in mining and metallurgy.
Key Features
Why field crews specify Heartwork
Abrasion class 1
Molecular weight ≥ 5 × 10⁶ — 8× wear life of Q235 steel in slurry service.
Self-lubricating
Ultra-low friction coefficient reduces pressure drop and pump energy consumption.
Chemical inert
Immune to acid, alkali and organic solvent attack encountered in tailings streams.
Flanged or fused
Choose flanged, socket-welded or extruded fitting joins to match your existing pipeline.
