Carbon steel WN flange shall be welded on both inner and outer layers. It is generally used in medium and high pressure pipelines. The nominal pressure of the pipeline is between 0.25 ~ 2.5MPa.
Carbon steel WN flange adopts concave convex sealing surface connection, and the installation is complex, so the labor cost, installation method and auxiliary material cost are relatively high.
