-Because of n<0. 0084, FRP process pipe enjoy good reputation of prominently saving energy; -Owing to their perfectly smooth surface, loss of fluid pressure head is kept to minmum level, and enable pipe dea, to be reduced without reducing the volume of flow or a saving to be made in the pumping costs; -Large dia pipe line used in long distance transportation can reduce cost for installation, heat preservation, free maintenance and anticorrosion; -Under the condition when medium appeared to be frozen, the pipe will not be broken; -Resistant to corrosion; --Resistant to pressure; --Resistant to heat; -The pipe has excellent dielectric strength, transparency and thermal insulation properties; -Poison Free; the pipe can be used to transport food.
