Lap Joint Flange Features

Lap Joint Flange Sizes

Lap Joint Flange Materials 

Lap joint flanges fit over a pipe with a flared or stub end. This allows the flanges to swivel freely to easily align bolt holes. These are ideal for systems whose design / layout may change or are frequently disassembled. The biggest advantage of lap joint flanges is that the flanges are not welded in place however its an overall much weaker connection than other flanges styles.
