Abstract

The invention discloses a high-strength glass reinforced plastic sewage pipeline which comprises a pipeline center lining layer, wherein a first winding strength layer is arranged on the outer surface of the pipeline center lining layer, a first sand inclusion strength layer is arranged on the outer surface of the first winding strength layer, a second winding strength layer is arranged on the outer surface of the first sand inclusion strength layer, a second sand inclusion strength layer is arranged on the outer surface of the second winding strength layer, a third winding strength layer is arranged on the outer surface of the second sand inclusion strength layer, and an external protective resin layer is arranged on the outer surface of the third winding strength layer. The high-strength glass reinforced plastic sewage pipeline has strong corrosion resistance and high strength, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a high-strength glass fiber reinforced plastic sewage pipeline. Background technique [0002] FRP is a composite material that has developed rapidly in the past fifty years. 70% of the output of glass fiber is used to make FRP. FRP has high hardness and is much lighter than steel. In recent years, FRP has been widely used in the manufacture of pipes, which has the advantages of light weight and strong corrosion resistance. But the strength of the existing FRP pipeline is not high enough, and the service life is short. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-strength FRP sewage pipe, which can solve the problems existing in the prior art, has strong corrosion resistance and high strength, and has a long service life. [0004] In order to solve the above technical problems, a ...
