Fiberglass pipelines are also called GFRP or FRP pipelines, are a type of lightweight, high-strength, and corrosion-resistant non-metallic pipeline. FRP pipelines are made by wrapping layers of fiberglass with a resin matrix onto a rotating mandrel according to the required process, and laying a layer of quartz sand as a sand layer between the fibers at a far distance. The reasonable and advanced wall structure of the pipeline can fully exert the material’s function, increase rigidity while satisfying the prerequisite for use strength, and ensure the stability and reliability of the product. With its excellent resistance to chemical corrosion, lightweight and high strength, anti-scaling, strong seismic resistance, longer service life compared to conventional steel pipes, low comprehensive cost, quick installation, safety, and reliability, the fiberglass sand pipelines are widely accepted by users.
