5.3.1.2 API type 6B flange connections Type 6B flange connections are of the ring joint type and are not designed for face-to-face make-up. The connection make-up bolting force reacts on the metallic gasket. The type 6B flange shall be of the through-bolted or studded design. Dimensions for type 6B integral flanges shall conform to ISO 1 0423. Dimensions for all ring grooves shall conform to ISO 1 0423. 5.3.1.3 API type 6BX flange connections Type 6BX flanges are of the ring joint type and are designed with a raised face. Depending on tolerances, the connection make-up bolting force may react on the raised face of the flange when the gasket has been properly seated. This support prevents damage to the flange or gasket from excessive bolt torque. Therefore, one of the flanges in a 6BX connection shall have a raised face. The type 6BX flange shall be of the through-bolted or studded design. Dimensions for type 6BX integral flanges shall conform to ISO 1 0423. Dimensions for all ring grooves shall conform to ISO 1 0423. Other weld preparations may be employed when the strength of the overlay alloy equals or exceeds the strength of the base material. 5.3.2 Studded end and outlet connections 5.3.2.1 General The two types of studded end and outlet connections (6B and 6BX) referred to in this American National Standard shall conform to ISO 1 0423. 6B and 6BX studded connections may be used as integral connections. The design for studded end and outlet connections shall be the same as specified in 5.3.1 .1 , except as required in 5.3.2.2 and 5.3.2.3.
5.3.2.2 Type 6B studded connections Dimensions for type 6B studded connections shall conform to ISO 1 0423 as it relates to the bore size, diameter of the bolt circle, and flange OD. The studded connection shall be fully machined in accordance with ISO 1 0423. Stud bolt holes shall be sized and located to conform to ISO 1 0423. The thread form of the tapped hole shall conform to the requirements of 5.3.3. The minimum depth of the full threads in the hole shall be equal to the diameter of the stud, and the maximum depth shall be in accordance with the manufacturer’s written specification. 5.3.2.3 Type 6BX studded connections Dimensions for Type 6BX studded connections shall conform to ISO 1 0423 concerning bore size, diameter of the bolt circle and flange OD. The studded connection shall be fully machined in accordance with ISO 1 0423. Stud bolt holes shall be sized and located in accordance with ISO 1 0423. The thread form of the tapped hole shall conform to the requirements of 5.3.3. The minimum depth of the full threads in the hole shall be equal to the diameter of the stud, and the maximum depth shall be in accordance with the manufacturer’s written specification. 5.3.3 Studs, nuts and tapped stud holes (bolting) Bolting for end and outlet connections, both studded and flanged, shall meet the requirements of ISO 1 0423.
