The purpose of this Standard Practice is to prevent interface and interference problems between tapping sleeves and tapping valves through the use of a positioning recess and mating raised face of the connecting flanges between tapping sleeves and tapping valves. The recess and raised face serve to ensure proper alignment of the tapping valve onto the tapping sleeve but do not affect the strength or the tightness of the joint.
