Dimensions of Type 6BX flanges for 2000 psi (13.8 MPa) rated working pressure.
Type 6BX flanges are of the ring joint type and designed with a raised face. Depending on the tolerances, the connection make-up bolting force may react on the raised face of the flange when the gasket has been properly seated. This prevents damage to the flange or gasket from excessive bolt torque.
All dimensions are in "mm" unless noted otherwise. Only flange sizes are in imperial units.
