Lap Joint Flange
The lap joint flange is practically identical to a slip-on flange except 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. Normally, a lap joint flange and a lap joint stub end are mated together is an assembly system.
The flanges we offer mainly include Welding Neck, Blind, Slip-on, Lap-Joint, Socket, Spectacle, Forged, Reducing and Threaded.
