Fiberglass sewage pipeline

1Characteristics of fiberglass sewage pipes
1. It has excellent physical properties, with a specific gravity of 1.8-2.1, about 1/4 of steel, and higher strength than steel, cast iron, and plastic. The weight of fiberglass pipes is generally not greater than 1/3 of steel pipes of the same specification, and its physical and mechanical properties are excellent. In addition, the expansion coefficient of fiberglass pipes is roughly equivalent to that of steel, and the thermal conductivity coefficient is only 0.5% of steel, making it a good thermal and electrical insulator.
2. Resistant to chemical corrosion, with a long service life, suitable for transporting various media such as acids, alkalis, salts, and organic solvents.
3. Excellent hydraulic characteristics, hydraulic characteristics are one of the important features of fiberglass reinforced plastic pipes. Excellent hydraulic characteristics mean that the fluid head loss is small, and smaller diameter or lower power delivery pumps can be selected to reduce initial investment in pipeline engineering, save electricity, and lower operating costs. The inner surface of fiberglass is quite smooth, with a general surface roughness rate of 0.0084, which can almost be considered as a "hydraulic smooth pipe". During operation, the inner surface of steel pipes, cast iron pipes, cement pipes, etc. often undergoes local corrosion and becomes increasingly rough, while fiberglass always maintains the smooth surface of the newly formed pipe.
4. Low installation and maintenance costs, generally speaking, fiberglass pipes do not require anti-corrosion treatment; The insulation layer can be reduced in thickness, or even without additional insulation treatment; The pipeline is relatively light, the lifting equipment has a small tonnage, and the power consumption is low. The length of fiberglass pipes is longer than that of cement pipes and cast iron pipes, and the number of joints is relatively reduced. All of these will reduce installation and maintenance costs, which has been proven by many engineering practices at home and abroad.
5. High design flexibility and short modification cycle. Fiberglass reinforced plastic (FRP) is a fiber-reinforced material impregnated with resin, which is wound layer by layer onto a core mold according to specific process conditions and appropriately cured. The pipe wall is a layered structure, and the physical and chemical properties of FRP can be adjusted by changing the resin system or using different reinforcement materials to adapt to different media and working conditions and produce FRP pipes with different pressure levels or special properties. The short modification cycle is a significant characteristic of fiber wound composite materials, which cannot be compared to isotropic metal pipes.
