UHMWPE Pipes: Advanced Material Properties, Composite Innovations, and Industrial Applications 1. Introduction Ultra-High Molecular Weight Polyethylene (UHMWPE) pipes—defined by a molecular weight of 1.5–15 million g/mol—represent a pinnacle in high-performance fluid and solid conveying technology. Distinguished by their entangled linear polymer chains and near-zero melt flow index, these pipes address the critical limitations of traditional steel, HDPE, and PVC alternatives in abrasive, corrosive, and extreme-temperature environments. Recent advancements in composite structures (e.g., steel-lined UHMWPE) have further expanded their capabilities, enabling high-pressure applications up to 6.4 MPa. Compliant with standards including ASTM D3306 and GB/T 32471, UHMWPE...
