API 6A flanges
JVS manufactures loose connector namely weld neck and blind flanged in various sizes and pressure ratings as specified in API 6A. Blind flanges are manufactured with test/inspection port and/or fluid cushion geometry as per API 6A. Ring grooves may overlay with corrosion-resistant material such as nickel-based alloy Alloy 625 to achieve best resistance against corrosion.
Type 6B flanges:
Type 6B flanges 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 ring gasket. The Type 6B flange shall be of through-bolted or studded design. Dimensions for type 6B flanges conform to API 6A. Raised face and/or counterbore are optional.
Type 6BX flanges:
Type 6BX flanges are of the ring joint type and designed with a raised face. Depending on tolerances, the connection make-up bolting force can 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. Type 6BX flanges are of through-bolted or studded design. Face-to-face contact is not necessary for proper functioning of Type 6BX flanges. Dimensions for type 6BX flanges conform to API 6A.
