What are the disadvantages of glass fiber reinforced sand pipe?
Not agree with the recommended answer, the same thickness of glass fiber reinforced plastic sand pipe and process tube, process tube stiffness is not low (can be calculated). The effect of sand inclusion is mainly to reduce the cost.
In brief, the disadvantage of FRP sand pipe is that the pipe is restrained by external environment, such as construction environment and span of support. Used in drinking water engineering, loess and sandy soil in the north are more suitable, but in ponds, marshes, mountains, then the pipeline backfill will increase the project investment. Used for overhead glass steel pipe lines, supporting the size of the gap is also the success or failure of the pipeline.
Glass reinforced plastic sand pipe is mainly to increase the rigidity of the pipe, the relative wall thickness of pure glass steel tube, low compressive strength, shock resistance decreased.
