Slip-On Flange
‌‌Slip-on flange is a pipe connection fitting and a type of random flange. ‌It is connected to the container or pipe through a fillet weld and is designed to be either integral or loose flange. The flange rings of slip-on flanges are of two types: with neck and without neck.
Compared with necked butt-weld flanges, slip-on flanges have a simpler structure and use less material, but their rigidity and sealing are slightly inferior to necked butt-weld flanges.
Slip-on flanges are widely used in the connection of medium- and low-pressure containers and pipelines.
