With the acceleration of urbanization and the improvement of environmental awareness, the demand for large-diameter drainage steel pipes will continue to increase. In the future, the development direction of large-diameter drainage steel pipes will focus more on technological innovation and improvement of environmental performance. For example, by adopting new materials, optimizing manufacturing processes, and strengthening anti-corrosion treatments, the corrosion resistance and service life of large-diameter drainage steel pipes can be improved; At the same time, strengthen the application of intelligent and automated technologies to improve the operational efficiency and management level of the drainage system.

Large diameter drainage steel pipes have a larger inner diameter, which can effectively increase drainage capacity and flow rate, meeting the needs of high flow drainage. Made of high-quality steel, it has high strength and rigidity, and can withstand large pressures and loads, ensuring the stable operation of the drainage system. After anti-corrosion treatment (such as coating with epoxy coal tar, hot-dip galvanizing, etc.), it can effectively resist corrosion and chemical erosion, and extend its service life. Large diameter drainage steel pipes are usually installed using spiral structures or flange connections, with tight connections and convenient installation.
