Differences in water quality between fiberglass steel pipes and steel pipes

Differences in water quality between fiberglass steel pipes and steel pipes
The inner lining of fiberglass pipe is made of food grade resin, which can ensure that the water quality meets the national standard (JC586-1995) and can be used for transporting and storing chlorinated drinking water and domestic water. Except for; In addition, the inner walls of fiberglass pipes under dark conditions do not grow microorganisms, so buried fiberglass pipes can further ensure the quality of tap water.
Due to the need for steel pipes to be coated with coatings, the GB13295-91 standard strictly stipulates that coatings should be insoluble in water and should not cause odors or odors in aquatic products. The harmful substances in the coatings should comply with the relevant regulations of the Ministry of Health on water diversion. In addition, due to the roughness of the steel pipe wall, it is difficult to achieve the smoothness of the inner wall of the fiberglass steel pipe even with the process of coating anti-corrosion materials. Moreover, long-term use can cause corrosion, leading to the growth of microorganisms and scaling, thereby affecting water quality.
Leakage resistance and water hammer resistance
The fiberglass steel pipe adopts a double ring rubber sealing rubber ring socket connection, and during installation, 100% pressure test is conducted at the connection to ensure that the sealing performance of the joint is 100% qualified. In addition, as fiberglass is a highly dense composite material, the pipe body not only does not allow water to seep from the inside out (such as sewage from the outside affecting farmland), but also cannot seep from the outside in (such as sewage from the outside of the pipe seeping in will affect the water quality inside the pipe).
When welding steel pipes, the required operating conditions are high, and the welding quality is often difficult to ensure due to limitations during on-site construction. Therefore, the reliability of the sealing at the welding point is not as good as that of fiberglass steel pipes, and the phenomenon of pipe explosion occurs at the welding point of the steel pipe.
Due to the high strength and good ductility of fiberglass sand pipes, they will not be damaged due to water hammer action and instantaneous overpressure.
It can be seen that the impermeability of fiberglass pipes is much superior to that of steel pipes.
