This is again similar to a slip-on flange, but it has a radius at the intersection of the bore and the flange face toaccommodate a lap stub end. The face on the stub end forms the gasket face on the flange. This type of flange is used in applications where section of piping systems need to be dismantle quickly and easily for inspection or replacement.
