1. Introduction Ultra-High Molecular Weight Polyethylene (UHMWPE) pipelines—defined by a molecular weight range of 1.5–15 million g/mol—have established themselves as a benchmark for reliability in fluid and slurry conveyance systems. Unlike conventional steel, HDPE, or PVC pipes, UHMWPE’s entangled linear polymer structure delivers a synergistic blend of abrasion resistance, chemical inertness, and low-temperature toughness that addresses the most pressing challenges in heavy industries. Manufactured via specialized plunger extrusion technology (to overcome its near-zero melt flow index) and compliant with global standards such as ASTM D3306, ISO 15494, and GB/T 32471, UHMWPE pipelines are engineered for diameters...
