Sand filled FRP pipe has smooth inner surface and is suitable for large
diameter (≥) φ 500mm) water transmission pipeline has the
characteristics of small wear resistance coefficient and good hydraulic
fluid characteristics, and the larger the pipe diameter, the more
obvious its advantages. On the contrary, when the pipeline
transportation flow is the same, the sand filled FRP pipe with smaller
inner diameter can be used in the project, so as to reduce the one-time
project investment. Compared with other pipes, sand mixed FRP pipes can
greatly reduce head loss and save pump power and energy.
[long service life, safe and reliable]
FRP sand pipe is designed with high safety factor. According to the
laboratory simulation test table, the service life of general water
supply and drainage sand mixed FRP pipe can reach more than 50 years,
twice that of steel pipe and concrete pipe. For highly corrosive media,
its service life is much longer than that of steel pipe.
