Slip On Flange

Slip On Flange refers to a kind of flange connected with the vessel or pipeline by fillet weld. It is an arbitrary flange. According to the integrity of the connection between the flange ring and the straight cylinder section, the design shall be checked according to the integral flange or loose flange. Flange rings are available with or without neck. Compared with the neck butt welding flange, the flat welding flange has simple structure and less material consumption, but its stiffness and tightness are not as good as the neck butt welding flange. Flat welding flange is widely used in the connection of medium and low pressure vessels and pipelines.
