The lap joint flange is practically identical to a slip-on except that it has a radius at the intersection of the bore and flange face. This radius is necessary to have the flange accommodate a lap joint stub end. The stub end is mated with the lap joint flange and used together in piping systems. There are many uses for this type of assembly, from saving costs to creating joint systems.

Lap joints do not come with any facing, and are therefore considered flat faced.

These flanges are available in all of our stainless steel and chrome-moly grades,from ½” to 24” and beyond, class 150 to 2500. We also stock popular sizes of large diameter LDS Lap Joint flanges in A105N, and can supply all sizes of LDS Lap Joints with longer lead times. We can also source many of your other specification requirements.
