Threaded coupling with water exclusion seal system |
摘要 |
An improved coupling for joining together tubular sections is disclosed. The coupling includes a water exclusion seal which is a pressure energized elastomeric seal positioned in a groove near each end of the coupling to form a radial seal between the unthreaded area at each end of the coupling and the unthreaded cylindrical area adjacent each end of the tubular section. A thread compound relief groove adjacent each seal groove has sufficient volume for thread compound that is squeezed from the threads during or after make-up.
