The invention discloses a lightweight FRP water delivery pipe and a processing technology thereof.The water delivery pipe comprises a water delivery straight pipe and a water delivery bent pipe, the water delivery straight pipe and the water delivery bent pipe are connected through an FRP flange or an FRP hoop, and the water delivery straight pipe and the water delivery bent pipe are both formed by winding resin pre-impregnated fiber reinforced composite material winding wires; a plurality of buffering mechanisms are arranged on the water conveying straight pipe in an array mode and detachably connected to the pipeline. The processing technology comprises the following steps: winding by taking steel as a core mold, and taking out the component core mold after the resin pre-impregnated fiber reinforced composite material is cured and formed; and assembling. The resin pre-impregnated fiber reinforced composite material winding wires are integrally formed for multiple times, the interface performance between winding layers at different angles is greatly improved, the overall synergistic effect of water delivery is improved, and the bending rigidity of the water delivery pipe is remarkably enhanced.
