　　Jieyang Bridge Cast Iron Drain Pipe Manufacturer Customized Circular Drain Pipe Rectangular Drain Pipe Overview With the rapid development of China's economic construction and the progress of people's living standards, the requirements for residential construction are also increasing. A smooth drainage network is one of the important infrastructures built into a city, providing strong support for people's daily life and production. According to relevant records, cast iron pipes have been used in people's daily production for hundreds of years. As early as the Hongwu period (1368-1399 AD), cast iron pipes were used in the Wumiao Sluice Canal in Nanjing; Since 1644 AD, a cast iron pipeline has been used in the Palace of Versailles in France, and it is still in use today. In the mid-1990s, with the advancement of production technology for cast iron pipes, many advantages of metal centrifugal cast iron pipes, such as high strength, long service life, low noise, strong flame retardancy and fire resistance, flexible seismic resistance, and renewable recycling, were highlighted. They regained recognition from society and shopping malls and were widely used in high-rise and super high-rise residences, municipal engineering, hospitals and campuses. This was the second rise of cast iron pipes.
