    Characteristics and installation method of FRP


    The following is about the characteristics and installation method of FRP.


    The existing underground pipeline detection equipment is mainly used to detect the metal pipeline, but the non-metal pipeline detection instrument is expensive, so it is impossible to detect the buried GRP at present, and other subsequent construction units are very easy to dig and damage the pipeline in the construction.


    At present, 0.5mm thick resin rich layer and ultraviolet absorber are made on the surface of surface mounted FRP pipe to delay the aging time. As the running time goes on, the resin rich layer and ultraviolet absorber will be damaged, which will affect its service life.


    The depth of covering soil is required to be higher. At present, there is no report about the large-scale use of glass fiber reinforced plastic pipes by large-scale water companies in China. As glass fiber reinforced plastic pipe is a new type of pipe, its service life is still unknown. As the main raw material of FRP is composed of unsaturated polyester resin and glass fiber, it can effectively resist the corrosion of acid, alkali, salt and other media, and the erosion of untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids. In general, it can maintain the safe operation of the pipeline for a long time. The hydraulic condition of FRP is good. Smooth inner wall, strong conveying capacity, no scaling, no rust, small water resistance. FRP is not only light weight, high strength, strong plasticity, convenient transportation and installation, but also easy to install various branch pipes, and the installation technology is simple. It has good anti-aging and heat resistance. The outer surface of the pipeline which has been used in the open air for a long time is added with ultraviolet absorbent to eliminate the radiation of ultraviolet rays on the pipeline and delay the aging of FRP pipeline.
