Facing Dimensions For Ring Joints
ANSI B16.5
DIMENSIONS are shown in inches, and conform to ASA Specification B 16.5, and API 5-G3.
RING JOINT flanges will be furnished in accordance with these details, unless otherwise specified by the purchaser. Lap joint stubs will also conform to these dimensions, except where designed for use with 3,
300, 400 & 600 lb. flances (such lap joint stubs will be made for Ring No. R30: pitch diameter 4 58").
DEPTH of groove is added to flange thickness except that on sizes marked (*), the groove will cut 132" into the minimum flange thickness.
