The glass fiber reinforced plastic pipe mainly uses glass fiber and products thereof as reinforcing materials, and uses unsaturated polyester resin, epoxy resin and the like with high molecular components as basic materials. The glass fiber reinforced plastic pipe has the advantages of unique strong corrosion resistance, low energy consumption for transportation, long service life (more than 50 years), convenient transportation and installation, low maintenance cost, low comprehensive cost and the like, and is widely applied to industries such as petroleum, electric power, chemical industry, papermaking, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transportation and the like.
