Slip On Flanges is a flange connected with a pipe by fillet welding. It is an arbitrary flange. Compared with the welding neck flange,it has a simple structure and saves materials, the rigidity and sealing performance are not as good as welding neck flange. It is widely used in the connection of medium and low pressure vessels and pipelines.
