A soundproof fiberglass pipe

Abstract

The invention discloses a soundproof fiber reinforced plastic pipeline which comprises a fiber reinforced plastic pipe main body, a buffering layer, buffering holes, a flexible layer, a soundproof layer, a filling layer, reinforcing ribs, an external protective layer and an internal protective layer. According to the soundproof fiber reinforced plastic pipeline, the problems that extremely high noise, which may severely affect sleep and rest of people at night, is caused by work of an existing steel pipeline, and a conventional fiber reinforced plastic pipeline does not have a heat insulation and heat preservation function and cannot perform heat insulation protection on the pipeline under a severe environment, in particular an environment with lower temperature, are effectively solved. Due to the arrangement of the soundproof layer, the noise in a pipe can be effectively suppressed, and the pipeline can be effectively subjected to heat insulation. Due to the arrangement of the filling layer and the reinforcing ribs in the filling layer, the structural strength of the fiber reinforced plastic pipeline cannot be reduced during mounting or transportation, so that the safety of the fiber reinforced plastic pipe is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of pipelines, in particular to a sound-insulating FRP pipeline. Background technique: [0002] FRP is a new type of industrial material that replaces steel with plastic. It is widely used in chemical industry, power plant, municipal engineering, sewage treatment, etc. due to its obvious advantages such as light weight, high specific strength, corrosion resistance, small frictional resistance, and long service life. It is widely used in important industrial fields, especially in industrial occasions such as coal mine drainage, grouting and gas pumping; fiber winding reinforced thermosetting resin pressure pipe is a kind of glass fiber reinforced plastic product, which uses a winding machine to wrap the tensioned pipe The winding sand is wound on the mandrel according to the winding curve, and the strength of the pipe wall is much stronger than that of the hand-wound FRP pipe. However, no matter how much the ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a sound-insulating FRP pipe in order to solve the above problems, which solves the problem that the existing steel pipes will cause a lot of noise during work, especially at night, the noise will seriously affect people's sleep and rest. Moreover, the traditional FRP pipeline does not have the function of heat insulation, and it cannot protect the pipeline in harsh environments, especially in environments with low temperatures.
