The manufacturing methods for water supports typically include two approaches: first, bending the cut steel plates into the shapes specified in the design drawings using a bending machine; second, welding an arched plate with two rectangular plates. Both methods meet the parameter requirements of the design standards. The material used varies depending on the pipe diameter; for diameters ≤630MM, Q235B steel is used, while cast steel 25 is used for diameters ≥720MM. An example of a circulating water support number is Dw=1220, with the number being Z12.1220S. Product models range from larger to smaller as follows: Z12.2020S, Z12.1820S, Z12.1620S, Z12.1420S, Z12.1220S, Z12.1120S, Z12.1020S, Z12.920S, Z12.820S, Z12.720S, Z12.630S, Z12.529S, Z12.478S, and so on. Each product must undergo pressure testing and leak detection before shipment, ensuring quality control and safety are always prioritized. Safe production starts from the source.
