Fiberglass Reinforced Plastic (FRP) Sand-Lined Pipe

Fiberglass reinforced plastic (FRP) pipes are lightweight, high-strength, and corrosion-resistant non-metallic piping. They are constructed by layering glass fibers with a resin matrix around a rotating mandrel according to specific manufacturing requirements, and quartz sand is evenly laid between the fibers to form a sand-laying layer. The wall structure is rational and advanced, maximizing material efficiency while enhancing stiffness, ensuring product stability and reliability. FRP sand-laying pipes are widely accepted by users for their excellent chemical resistance, lightweight strength, non-scaling, strong seismic resistance, longer service life compared to standard steel pipes, lower overall cost, quick installation, and safety.
