Slip-On Flange
Slip-On Flanges are not welded directly to the pipeline but are connected to the outside of the pipeline with bolts, making them easy to install and remove. These flanges are used in low or medium pressure pipeline systems, and sealing surfaces can be made smooth, concave-convex, or tongue-and-groove, to meet various sealing requirements. Compared to other types of flanges, Slip-On flanges generally have a lower cost and are widely used in pipeline systems in industries such as water treatment and shipbuilding.
