摘要： A threaded and coupled connector with tapered threads having equivalent heights (same height on pin and box threads), negative load flanks, biased tapered thread forms with a torque shoulder formed by pin noses that abut at a central point within a coupling constructed from standard coupling stock. The connection design meets the internal/external pressure performance requirements of industry standards with capabilities equal to or exceeding those of “premium” connections, with a coupling constructed from thin walled coupling stock.

摘要： Connectors and connections that enhance mechanical and sealing engagement between the ends of tubular bodies that are radially expanded by a forging tool. The connectors are designed to maintain or restore mechanical and sealing engagement following expansion. The connections are made by joining components that exhibit different spring back characteristics following mechanical deformation. Dissimilar material may be used for the connectors or the connected components can be made of the same materials but dimensioned and configured to exert an interfering force between engaged components following expansion. In operation, a material or component with a high spring back characteristic is positioned adjacent a material or component having a lower spring back characteristic. Following passage of a forging tool, the expanded components spring back differently toward their original unexpanded dimensions to produce the enhanced seal or mechanical engagement. The materials of the end connectors are selected and positioned such that a compressive or locking force is exerted between the different component of the connectors due to the difference in the spring back of the materials or components.

摘要： A threaded tubular connection having a sleeve seal for maintaining pressure sealing capabilities within the connection when exposed to extreme pressure and/or temperature variations. The sleeve seal forms a third part of the pin and box connection and is positioned axially intermediate the ends of the threaded engagement of the connection. The sleeve seal is constructed of a corrosion resistant metal having a Modulus of Elasticity and thermal characteristics that work with the Modulus of Elasticity and the thermal characteristics of the pin and box material to minimize leakage following exposure to extremes of pressure differentials and temperature.

摘要： A threaded connection for improving fatigue resistance to cyclic loading is disclosed. The threaded connection basically comprises a pair of interlocking members having corresponding radially inner and radially outer spiral threads thereon, each spiral thread including a spiral compression flank and a spiral tension flank wherein at least one of the spiral compression flanks and spiral tension flanks on the inner spiral threads are in mating planar engagement with a corresponding spiral compression flank and spiral tension flank on the outer spiral thread. Axial spacing between the tension flanks and the compression flanks on the radially inner and radially outer spiral threads further define a stress reducing spiral root surface on at least one of the radially inner and radially outer threads and a corresponding crest surface on the other radially inner and radially outer spiral threads. Resistance to cyclic loading on the threaded connection is improved because of the stress reducing spiral root surface which includes a substantially linear profile spaced axially between the compression flank of one thread and a tension flank of an adjoining thread. The stress reducing spiral root surface intersects the compression flank and tension flank along corresponding first and second axially spaced rounded surfaces each having a radius of at least 0.015 inches. Loading is therefore, distributed evenly over the threads rather than being concentrated at what normally would be a sharp juncture formed in the root of the thread.
摘要翻译：公开了一种用于改善对循环加载的耐疲劳性的螺纹连接。螺纹连接基本上包括一对在其上具有对应的径向内部和径向外部螺旋螺纹的互锁构件，每个螺旋螺纹包括螺旋压缩侧面和螺旋张力侧面，其中螺旋压缩侧面和螺旋张力中的至少一个在内侧螺旋螺纹与外螺旋螺纹上的相应的螺旋压缩侧面和螺旋张力侧面配合平面接合。在径向内部和径向外部螺旋形螺纹之间的张力侧翼和压缩侧面之间的轴向间隔进一步限定在径向内部和径向外部螺纹中的至少一个上的应力减小的螺旋根表面和在另一个径向外部螺纹上的相应的顶部表面径向外螺旋线。由于应力减小的螺旋根表面，包括在一个螺纹的压缩侧面和相邻螺纹的张力侧面之间轴向间隔开的基本上线性的轮廓，因此提高了螺纹连接上的循环负载的耐受性。应力减小螺旋根表面与相应的第一和第二轴向间隔开的圆形表面相交于压缩侧面和张力侧面，每个圆形表面的半径至少为0.015英寸。因此，装载是均匀分布在螺纹上，而不是集中在通常在螺纹根部形成的尖锐的接头处。
