  • Publication number: 20110233925
    Abstract: A threaded joint has a seal flange or device in order to avoid the seepage of external pressure of fluid inside the pipe. The sealing flange has an L-shape and is interposed in a housing between a pin and a box, and the flange-like annular portion of the flange helps to verify proper positioning of the flange during make-up and contributes to increase tightness of the joint because the external fluid pressure improves adherence of the sealing flange against the contact surfaces of the joint.
