Resin, fiber reinforcement, and filler are the main raw materials for fiberglass pipes. There are many advantages to using fiberglass pipes, as follows:
- Good corrosion resistance. Since the main raw materials of FRP are polymer unsaturated polyester resin and glass fiber, it can effectively resist the corrosion of acid, alkali, salt, and other media, as well as the corrosion of untreated domestic sewage, corrosive soil, chemical wastewater, and many chemical liquids. In general, pipelines are safe to operate for a long time.
- Good design ability. FRP pipelines can be designed and manufactured with different pressure levels and stiffness levels according to the specific requirements of users such as different flow rates, different pressures, different buried depths, and loads.
- Good abrasion resistance. Put the water containing a lot of mud and sand into the pipeline to carry out the comparative test of rotating wear. After 3 million rotations, the wear depth of the inner wall of the detection pipe is as follows: 00.53mm of steel pipe coated with tar and enamel. Therefore, FRP has good wear resistance.
Fiberglass Pipes
The following points should be paid attention to when laying fiberglass pipes:
- The bottom of the trench of the FRP pipeline is uneven, and there are sharp objects such as hard clods and stones that obstruct the pipeline.
- There is a large amount of water in the pipe trench, and the pipe trench collapses.
- The impact of sharp objects such as stones and mechanical backfill in the backfill of the pipe trench.
With the acceleration of urbanization and the need for advanced science and technology, pipes and pipe fittings have rich varieties and specifications, increased production, and improved quality, especially the rapid development of glass fiber-reinforced plastics (FRP), which has become a hot material today.
