The "Threaded Steel Pipe for Drainage" has now been officially recognized as a product standard for the urban construction industry, with the designation CJ/T 431-2013. It became effective from October 1, 2013, marking an important step in standardizing drainage systems within urban infrastructure projects.
This standard was published by the China Standard Press, which is affiliated with the Institute of Standards and Qualifications under the Ministry of Housing and Urban-Rural Development. The release of this standard reflects the government's commitment to improving the quality and safety of construction materials used in municipal projects.
The official announcement was made on May 24, 2013, and it is expected to play a key role in enhancing the efficiency and durability of drainage systems across cities. By establishing clear technical requirements for threaded steel pipes, this standard will help ensure consistency and reliability in construction practices.
As a result, manufacturers, engineers, and contractors involved in urban development will now have a reliable reference to follow when selecting and installing drainage pipes, ultimately contributing to better urban planning and infrastructure management.
