摘要： A rotating control drilling device includes an upper sealing element and a lower sealing element positioned around a drillstring and forming a chamber therebetween and a leak detection device. The leak detection device includes a piston in communication with the chamber, a magnet disc disposed on an end of the piston, and a plurality of magnetic sensors arranged in a magnetic sensing ring around the rotating control drilling device. Upon reaching a selected critical pressure in the chamber, a spring is configured to compress as the magnet disc is positioned proximate to the plurality of magnetic sensors. Furthermore, a method to detect leaks in a rotating control device includes positioning a leak detection device in communication with a chamber located between upper and lower sealing elements and signaling with the leak detection device when a pressure of the chamber exceeds a selected critical pressure.

摘要： An improved internal line up clamp (10) is disclosed which has an integral back up ring (12). A first set of pipe clamps (22) move radially outward to engage the inner surface of a first pipe (14). A second set of pipe clamps (62) and a set of back up ring segments (88) are simultaneously moved radially outward into engagement with the inner surface of the pipes. The back up ring segments (88) are spring loaded to exert a relatively constant back up force against the inner surface of the pipes at the weld. In a modification, a fill block (118) can be used to fill the gap between adjacent back up ring segments when engaging the inner surface of the pipe.
