Fiberglass reinforced sand pipes are a new type of composite material pipes with excellent performance, which exhibit superior characteristics that traditional pipes (metal pipes, concrete pipes, plastic pipes) cannot match. Below are some key points about fiberglass reinforced sand pipes.
Glass fiber reinforced sand pipe is a new type of composite material pipe with excellent performance, which has superior performance that cannot be compared with other traditional pipes (metal pipes, concrete pipes, plastic pipes). Below are some knowledge points about glass fiber reinforced sand pipes.
The inner and outer surfaces of glass fiber reinforced sand pipes are lubricated, suitable for large diameter (≥φ500mm) water delivery pipes, with a small friction coefficient and good hydraulic fluid characteristics. Conversely, you will find that under the same flow conditions, a smaller diameter sand-filled glass fiber pipe can be used instead, thus reducing the initial engineering investment. Compared with other pipes in the water delivery process, sand-filled glass fiber pipes can also significantly reduce head loss, saving pump power and energy. Especially its high safety factor. According to laboratory simulation test data, the lifespan of sand-filled glass fiber pipes for water supply and drainage can reach50years, which is twice that of steel and concrete pipes. For more corrosive media, its service life is far superior to that of steel pipes. The scientific and reasonable selection of resin for the pipe lining and the design of the layering process ensure that glass fiber reinforced sand pipes have excellent waterproof, seepage-proof, and chemical corrosion resistance. Additionally, it should be noted that its inner wall roughness coefficient is only0.0084, while steel pipes are0.04, concrete pipes are0.014, and cast iron pipes are0.013Therefore, glass fiber reinforced sand pipes can significantly reduce fluid pressure loss along the way, improving delivery capacity20-30%..
Glass fiber reinforced sand pipes can be designed to meet various special application requirements of users, producing pipes of various specifications, pressure ratings, stiffness ratings, or other special functions, with a wide range of applications. They also have good corrosion resistance, requiring no rust prevention, pollution prevention, insulation, or maintenance methods, and buried pipes do not require cathodic protection, saving a lot of maintenance costs. Glass fiber reinforced sand pipes have special chemical corrosion resistance, making their pipe products suitable for transporting different media such as acids, alkalis, salts, and organic solvents. They are lighter than steel pipes of the same specification, have excellent physical and mechanical properties, and their thermal expansion coefficient is roughly equivalent to that of steel. Of course, hydraulic characteristics are one of the main features of glass fiber pipes. Excellent hydraulic characteristics mean low fluid head loss. In this case, you also need to know that glass fiber reinforced sand pipes can also choose a smaller pipe diameter or the same power delivery pump, thus reducing the initial investment in pipeline engineering, saving electricity, and lowering operating costs. The inner surface of glass fiber pipes is smooth. During operation, the inner surfaces of steel pipes, cast iron pipes, cement pipes, etc., often experience localized corrosion, becoming rougher, while glass fiber pipes maintain a smooth surface.
By discussing some knowledge points about glass fiber reinforced sand pipes, we should know these when using them in the future. If you are still unaware, you should read carefully. Well, that’s all for today’s knowledge points, and I hope it can be helpful to everyone.
