Lap Joint Flanges

Lap Joint Flanges (Loose Flanges) are used with a corresponding stub-end that “inserts” in the inside of the flange.  The main benefit of this type of flange, is that once the pipe welds to the insert stub-end, the flange then can rotate for easier alignment of the bolting holes. However, lap joint flanges and their stub-ends’ ability to hold pressure is about the same as slip-on flanges.  They are not suitable for situations with a high external or changing loads of force.  They do provide an advantage in a piping system that needs frequent dismantling for inspection or to remove build-ups.

A lap joint flange is very similar to a slip-on flange, with the main difference being that it has a curved radius at the bore and face to house a lap joint stub-end. Lap joint flanges and stub-end assemblies are typically used in situations where requires frequent dismantling for examination.
