Reinforcement plastics with glass fibers or their products as reinforcing materials are called glass fibre reinforced plastics or glass fibre reinforced plastics. Because of the different types of resin used, it is known as polyester FRP, epoxy FRP and phenolic FRP. Glass is hard and fragile, has good transparency, high temperature resistance, corrosion resistance and other properties; at the same time, steel is very hard and not fragile, but also has the characteristics of high temperature resistance.
FRP Pipe
So people began to think that if we can make a kind of glass with hardness, high temperature resistance, corrosion resistance, but also with the characteristics of steel as hard and unbreakable, then this material will be of great use. After research and experiment, people finally produced such a composite material. It is a fiberglass steel pipe that can stand shoulder to shoulder with steel.
FRP pipe has many advantages, such as strong corrosion resistance, smooth inner surface, low energy consumption, long service life (more than 50 years), convenient transportation and installation, no maintenance and low comprehensive cost, in petroleum, electric power, chemical industry, paper making, urban water supply and drainage, factory sewage treatment, desalination of seawater, gas transportation and other industries. It has been widely used.
With the acceleration of China's urbanization process and the balance and protection of population, resources and environment, governments at all levels have increased their investment in urban infrastructure year by year. Considering the needs of advanced science and technology, the varieties and specifications of pipes and fittings are constantly enriched, the output is constantly increasing, and the quality is constantly improving, especially the development of plastic pipes. Quickly, it has become a hot spot of investment nowadays. FRP is one of them.
