Abresist basalt-lined piping is tougher than grit, sludge, limestone, incinerator ash or bio-solids fertilizer conveyed in wastewater plants, and lasts five times longer than cast iron. Pipes, elbows and fittings are custom engineered. It is excellent for slurries or pneumatic systems, pressure or vacuum conditions. The image shows 78-in.-diameter pipe for handling combined sewage at a major Northeast city pumping station; the lining protects against abrasive failure.
