Features of fiberglass tube:
- Good corrosion resistance. Since the main raw materials of glass fiber steel pipe are composed of unsaturated polyester resin and glass fiber with high polymer content, it can effectively resist the corrosion of acids, alkalis, salts and other media, as well as untreated domestic sewage, corrosive soil, chemical wastewater and many others. The erosion of chemical liquids, in general, can maintain the safe operation of pipelines for a long time.
- Good aging resistance and heat resistance. FRP pipes can be used for a long time in the temperature range of -40°C to 70°C, and the high temperature resistant resin with special formula can also work normally at temperatures above 200°C. For pipes that have been used in the open air for a long time, ultraviolet absorbers are added to the outer surface to eliminate the radiation of ultraviolet rays to the pipes and delay the aging of the FRP pipes.
- Good antifreeze performance. Under minus 20℃, the tube will not freeze after freezing.
