  Pipe is indispensable in urban construction. In order to adapt to different environmental requirements, the pipeline industry has been developing continuously. From the beginning, plastic pipes and steel pipes, now the most popular PSP steel-plastic composite pipes, the quality performance of pipes is stronger than that of the generation, especially the PSP inspection and control in recent years, which is a new type of composite. Pipeline, pipeline has a very wide range of applicability.
  PSP inspection control lining is food grade modified epoxy powder coating, epoxy resin, the outer layer of advanced process, and melted exterior wall, spray or adsorption and high temperature curing epoxy resin powder coating of new composite pipe, overcome the steel pipe is easy to rust, heavy pollution, and the strength of plastic pipe is very low, a large number of expansion and short service life defects. It is easy to deform, but the common advantage of steel pipe and plastic pipe is that they have high pressure and strong impact resistance compared with plastic pipe; the inner and outer layers of plastic have anti-corrosion effect, with smooth inner wall, chemical corrosion resistance, pollution-free, low fluid resistance, no scaling, no breeding of microorganisms, no secondary pollution of fluid, and so on. High pressure, long service life, less maintenance and other advantages. The product has reasonable structure, excellent performance, long service life and high cost performance.
  PSP steel-plastic composite pipeline has low expansion coefficient and no shrinkage. In addition, food grade epoxy resin is a polar material with strong adhesion to steel pipe. It is not easy to separate or fall off for a long time at room temperature.
