摘要： A threaded joint for steel pipes comprising a pin (1) and a box (2). The pin has a male thread (11) and a lip (12) which comprises (i) a sealing surface (13) and (ii) a nose portion (16) provided with a shoulder surface. The box has a female thread (21), a sealing surface (23) and a shoulder surface. The shoulder surface of the pin comprises two distinct adjacent surfaces, main shoulder (14) in the inner side and sub shoulder (15) in the outer side. Correspondingly, the shoulder surface of the box comprises two distinct adjacent surfaces, main shoulder (24) in the inner side and sub shoulder (25) in the outer side. The main shoulder surfaces of the pin and box are disposed such as to prevent a radially inward deformation of the lip end, and the sub shoulder surfaces of pin and box are disposed such as to limit a radially outward deformation of the lip end. The main shoulder of the pin has a greater radial dimension than said sub shoulder of the pin, and at least the main shoulder surface of the pin is in axial abutment with at least the corresponding main shoulder surface of the box.

摘要： A method for making-up a wedge thread connection comprising a pin member and a box member includes applying a pipe dope to at least one of the pin member and the box member, wherein the pin member and the box member comprise corresponding wedge threads, reducing the viscosity of the pipe dope at least temporarily, and rotating the pin member relative to the box member to make-up the wedge thread connection, wherein the rotation occurs while the viscosity of the pipe dope is at least temporarily reduced. A collar to be used with a tong assembly in making-up a threaded connection between a pin member and a box member includes at least one power unit configured to temporarily reduce the viscosity of pipe dope applied to at least one of the pin member and the box member, and an inner surface having a selected diameter to correspond to an outer diameter of at least one of the pin member and the box member.

摘要： A thread form for a tubular connection of the type having a pin member (31) adapted to be made-up with a box member (37) to form a pipe joint as shown. The pin member has pin threads with thread crests (33) and thread roots (35) which are adapted to be made-up with a mating box member (37) having a complimentary thread structure. The pin thread crests are formed between a stab flank (39) and a load flank (41) of the pin thread. The pin thread has a multi-faceted (69, 71, 73) complex profile stab flank for engaging a mating stab flank on the complimentary box member to provide a wedging interfit between the surfaces of the pin and box threads. The pin and box threads are also helically structured as a wedge.

摘要： The tubular connection (10) includes a pin member (16) having external tapered threads (20) extending from a pin nose (29) to a pin base (23) and box member (18) having internal tapered threads (32) extending from a box base (33) to a box nose (34). The tapered threads are square or near square threads having a stab (50, 60) and load (70, 72) flanks with accommodating grooves. The stab flanks (50, 60) have corner chamfers (52, 62) which engage upon stabbing the pin member (16) into the box member (18). The corner chamfers (52, 62) increase the clearances between the threads and grooves and guide the crests (58, 68) to the root (59, 69) openings upon relative rotation of the pin (16) and box (18) members. The stab flanks (50, 60) may have an increased thread width at the thread pitch line forming cam flanks which cam the threads into the grooves. The crests (58, 68) and roots (59, 69) of the threads interferingly engage.

摘要： A tubular connection (10, 12) is shown having wedge threads (24, 26), the individual threads preferably interlocking by having wider crest dimensions than respective root dimensions, but with the stab flanks (30) and load flanks (32) generally angling in the same direction with respect to the longitudinal axis of the connection. Thus, when the stab flank is positive, it is less positive than the load flank is negative. Conversely, when the stab flank is negative, it is more negative than the load flank is positive. Preferably, the roots and crests radially interfere prior to full makeup. The connection achieves distribution over the entire thread length of the bearing stresses that resist torsional makeup, of the torque load, and of sealing. The slant of the flanks achieves self-centering of the pin member with respect to the box member either during assembly or disassembly depending on the angling in the respective embodiments.
摘要翻译：示出了具有楔形螺纹（24,26）的管状连接件（10,12），各个螺纹优选地通过具有比相应的根部尺寸更宽的顶部尺寸而互锁，但是具有刀尖侧面（30）和负载侧面（32）在相对于连接件的纵向轴线的相同方向上。因此，当胫骨侧面为正时，其负载侧面为负，则为正。相反，当双方的侧面为负时，其负载侧面为正，则为负。优选地，根部和顶部在完全化妆之前径向地干扰。该连接实现了抵抗扭转构造，扭矩负载和密封的轴承应力的整个螺纹长度的分布。根据各实施例中的角度，侧面的斜面在组装或拆卸期间相对于箱构件实现自定心。

摘要： A tubular member connection system (11) includes a pin (15), external pin threads (17), and an annular pin lip (21) at a shoulder surface (20) of the pin. A box (27) has internal box threads (29) and an annular box lip (31) at an end surface of the box. The box threads are shaped to mate with the pin threads to releasably secure the pin to the box. A pin recess (22) is formed in an outer diameter surface of the pin, the pin recess extending in an axial direction from the pin lip. A pin key (59) is selectively fastenable within the pin recess, the pin key having pin teeth (69) on an outer edge of the pin key. The box teeth (33) are located in the box. The box teeth (33) selectively mate with the pin teeth (69) and resist rotation of the pin relative to the box.
