Abstract

The invention relates to a pipeline composite abrasion resisting functional layer and an abrasion-resisting pipeline inner wall. The pipeline composite abrasion resisting functional layer is characterized in that a multi-direction woven fiber cloth abrasion-resisting enhancing layer and an axial woven fiber cloth abrasion-resisting enhancing layer are sequentially compounded with the surface of the pipeline inner wall as the inner side; the multi-direction woven fiber cloth abrasion-resisting enhancing layer is formed through resin impregnation and compounding of multi-direction woven fiber cloth; and the axial woven fiber cloth abrasion-resisting enhancing layer is formed through resin impregnation and compounding of axial woven fiber cloth. The abrasion-resisting pipeline inner wall is characterized in that the integrated enhanced abrasion-resisting inner wall is composed of the abrasion resisting functional layer, an anti-permeation layer and a fiber structure layer through organization. Abrasion resistance, permeation resistance, high strength, high rigidity and corrosion resistance are characteristics, and accordingly the service life of a glass steel pipeline is prolonged.

Description

technical field [0001] The invention relates to a composite wear-resistant functional layer of a pipeline, an inner wall of a wear-resistant pipeline and a manufacturing method thereof, belonging to the technical field of pipelines and manufacturing methods. Background technique [0002] FRP pipes are currently used in the field of fluid transportation because of their designability, convenient molding, good corrosion resistance, low weight, and long life. However, due to its low wear resistance, it is mostly used in petrochemical pipelines with small and medium diameters and pure fluids. The design of such pipelines does not need to pay attention to the wear resistance of the pipe wall to meet the pipeline strength requirements, and the pipeline materials meet the corrosion resistance requirements. The production can meet the anti-seepage requirements. [0003] For the transportation of fluids containing solids, such as fluids containing sand, stones and other impurities...
