Material selection of flue gas desulfurization pipeline by ammonia method? What are the advantages and disadvantages of PVC compared with FRP?
Comparison between PVC and FRP;
1, performance: corrosion resistance is almost the same;
2. Strength: The mechanical strength of FRP (steel lined PE) is obviously better than that of PVC, so the compressive strength is stronger than that of PVC;
3, construction: FRP can use threaded joints, easy to install, good quality, PVC is generally glued, because of temperature problems, quality is difficult to guarantee;
4, price: FRP is much higher than PVC, and the cost is relatively high;
Consider maintenance and service life. For quality assurance, I think FRP is the first choice.
