Abstract: The load flanks (15) in the male threaded portion (11) of the pin (10) and the load flanks (24) in the female threaded portion (21) of the box (20) have a flank angle ¸ of less than 0 degrees. The female threaded portion (21) is divided into, in order from near the seal surface (26), an incomplete thread section (21b) and a complete thread section (21 a). In the female threaded portion (21), over the entire area including the two thread sections (21a, 21b), roots (23) collectively define a single tapered periphery. The incomplete thread section (21b) has a length of at least three times the thread pitch and has a thread height lower than a thread height of the complete thread section (21a). In a made-up state, the shoulder surfaces (17, 27) are in contact with each other, the seal surfaces (16, 26) are in contact with each other, and in the incomplete thread section (21b), clearances are provided between the roots (13) of the male threaded portion (11) and the crests (22) of the female threaded portion (21). Consequently, sealing performance against external pressure is maintained and sealing performance against internal pressure is improved.

Abstract: A conduit seal assembly includes an outer conduit having a first end with a first opening and a second end, opposite the first end, with a second opening. A first seal is positioned in the first opening for resisting a first temperature, and a second seal is positioned in the second opening for resisting a second temperature less than the first temperature. The first and second seals define a cavity and provide an air-tight seal of the cavity, and the assembly includes a monitoring assembly configured to sense a characteristic in the cavity.

Abstract: A tubular threaded joint has a pin and a box. Each having a contact surface comprising a threaded portion and an unthreaded metal contact portion including a seal portion and a shoulder portion. A solid lubricating coating having a relatively high Knoop hardness is formed on a portion including the shoulder portion of the contact surface, such as the unthreaded metal contact portion including the shoulder portion and the seal portion, of at least one of the pin and the box. A solid lubricating coating having a relatively low Knoop hardness is formed at least on the remaining portion of the contact surface, such as the threaded portion. The threaded joint has excellent galling resistance, gas tightness, and rust preventing properties. The joint does not readily undergo yielding of shoulder portions even when made up with a high torque, thereby making it possible to perform makeup in a stable manner.
