THREADED JOINT WITH ELASTOMERIC SEAL FLANGE.

摘要

A threaded joint (1) has a seal flange (4) or device in order to avoid the seepage of external pressure of fluid inside the pipe. The sealing flange (4) has an L-shape and is interposed in a housing (10) between pin (3) and box (2), and the flange-like annular portion (6) of the flange (4) helps to check the right 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 (1)..
