Steel wire reinforced epoxy fiber composite pipeline and preparation process thereof

Abstract

The invention relates to a steel wire reinforced epoxy fiber composite pipeline. The pipe wall of the composite pipeline is of a structure comprising four layers which sequentially are an epoxy resinglass fiber reinforced plastic fiber inner-liner layer, an inner epoxy glass fiber layer, a steel wire related epoxy resin glass fiber layer and an epoxy resin glass fiber l outer protection layer from inside to outside; a reinforced layer winds on the steel wire related epoxy resin glass fiber layer; after the pipeline is winded, a reinforcing rib is added every other 1 meter outside the pipeline; each reinforcing rib is formed by a steel wire, fiber and epoxy resin through winding; the width of each reinforcing rib is 15CM; and the thickness of each reinforcing rib is 1 to 2 times of the thickness of the pipe wall. By calculating on the basis of each meter, the diameter being 1m, the wall thickness being 17.5mm and the total weight being 116kg, the weight of the epoxy resin glass fiber reinforced plastic fiber inner-liner layer is 13kg, the weight of the inner epoxy glass fiber layer is 32.57kg, the weight of the inner epoxy glass fiber layer is 43.65kg, and the weight of the epoxy resin glass fiber l outer protection layer is 26.78kg. The steel wire reinforced epoxy fiber composite pipeline is simple to prepare, stable in high water pressure resistance, water hammer resistance and ring stiffness which are 1 to 2 times higher than the design requirement, good in corrosion resistance and breaking stretchability, large in production caliber, light in dead weight, high in toughness and excellent in cost performance.

Description

technical field [0001] The invention relates to the field of pipeline preparation, in particular to a steel wire reinforced epoxy fiber composite pipeline and a preparation process thereof. Background technique [0002] China's current underground water supply and drainage pipelines, especially large-diameter water supply and drainage pipeline projects, are a very huge market. However, over the years, engineering accidents such as pipeline rupture, pipeline breakage, pipeline deformation and collapse have occurred in water supply and drainage projects, some of which are caused by humans and some are The quality of the pipe itself is caused. In any case, as long as there are engineering quality problems, it will cause huge losses to the country and the people. In order not to cause similar accidents and not cause losses to the country and the people, the technical quality is easy to supervise and manage. These two channels are to allow everyone to supervise their own quality...
