PURPOSE
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 connecitng 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 nto affect the strength or the tighness of the joint.
SCOPE
1.1 This Standard Practice establishes flange and gasket dimensions which define the interface between
tapping sleeves and tapping valves.
1.2 This Standard Practice establishes dimensions for these special connecting flanges and gaskets of
nominal sizes from NPS 2 through NPS 60 (DN 50 through DN 1500) for water and sewerage systems.
1.3 This Standard Practice establishes pressure-temperature ratings for the connecting flanges.
