The Abrasiguard AD-Series Polyurethane Lined Pipe is a custom reducer used to connect two pipe diameters of different sizes. It may be built as a concentric reducer to join two pipes on the same axis or an eccentric reducer to connect a larger upstream pipe to a smaller downstream one.
It features Abrasiguard AX-100, a high-performance polyurethane liner designed for slurry hydrotransport applications. The liner offers a wide temperature range, very high hydrolysis resistance, chemical compatibility with most fluids, and very low friction loss coefficient.
The Abrasiguard AC reducer is used in mineral processing plants, concentrate pipelines, tailings pipelines, oil sands pipelines, and dredging.
