摘要： A taper threaded joint, wherein a clearance (L1[mm]) between the thread top face (1a) of a tapered male thread (1) and the thread bottom face (2b) of a tapered female thread (2) or a clearance (L2[mm]) between the thread bottom face (1c) of the tapered male thread (1) and the thread top face (2c) of the tapered female thread (2), whichever comes smaller (L[mm]), is so related as delta 2L if an interference amount is required for the thread part, whereby a thread having sufficient tensile and compressive resistance forces can be manufactured easily with a correct working allowance and, particularly in a threaded joint for well pipe having a metal seal part, a reliability can be increased because the sealability thereof is excellent.

摘要： In the tool joint of the drill pipe having a pair of female screw threads (4) and male ones (3) at the opposite ends thereof, shoulder parts (5) are formed respectively on the outer surface side of the male threaded part and the inner surface side of the female threaded part so that: joint parts may be in plane contact with each other at two places; a length from the shoulder part formed on the pipe body side of each threaded part to the foremost end is made shorter than an engaging depth of the shoulder part of the general purpose tool joint as well as than the engaging depth of the female threaded side of said joint; and a clearance at inner shoulder parts is made 0 to 0.5 mm when tightened by hand. In contrast with the conventional API tool joint having an external shoulder, a tool joint of this invention is additionally provided with an internal shoulder to withstand excessive torque acting thereon while being used and interchangeable with the API tool joint.

摘要： A coupling system between tubular members such as tubing, pipes, casing and liner for location in a well bore in which the ends of each tubular have cooperating profiled sections. The profiled sections are arranged coaxially and a radially applied force is applied to form a metal to metal sealed connection. At least one profiled section includes a projection, the projection containing an overhang to the surface of the tubular member, the overhang locking with the opposing profile when the force is applied to provide a coupling with increased burst and collapse rating. Embodiments are provided of arrangements of overhangs such as oppositely directed overhangs and interlocking overhangs.

摘要： The joint consists of the male and female elements with trapezoidal tapered threads with 1:16 taper performed correspondingly on the external and internal surfaces of its ends. Load flank inclination angle of the thread profile of the male and female elements is 2-4 to the thread axes normal line and lead-in flank inclination angle of the thread profile is 9-11 to the thread axes normal line. The joint is performed with inner sealing unit, formed by intercontacting bearing end surfaces located perpendicularly to the thread axis line. The bearing end length of the male element is 6,9-100,3 mm. High sealability of the joint under sufficient multidirectional loads applied is preserved as well as high durability of the joint, of its improved make-up features, internal casing pipes string flushness.

摘要： A tubular connection is formed by a box member and a pin member, each of which has a tapered constant pitch thread. A profiled defined by the thread of at least one of the pin member and the box member results in a pitch line (44) that is a stepped pitch line. The stepped pitch line configuration may produce a wide radial band of substantive contact between the stab flanks of the pin member and box member upon full make-up of the connection.
