Abstract: A technique facilitates connection of tubulars along a tubing string via a linear motion. A first tubular is provided with a first connector end having a non-circular transverse cross-section, and a second tubular is provided with a second connector end having a corresponding non-circular transverse cross-section. The non-circular cross-section and the corresponding non-circular cross-section are designed to matingly engage when the first and second tubulars are moved linearly toward each other to form a tubing string. A seal is provided to seal the first connector end with the second connector end once linearly engaged. A locking mechanism may be employed to linearly lock the first connector end with the second connector end.

Abstract: Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as “torque-less” connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability.

Abstract: A fluid check piping of an embodiment includes a piping main body, a check window, and a check plate. The piping main body is arranged along a horizontal direction, and a fluid flows through an inside of the piping main body. The check window is provided on an upper portion of a circumferential wall of the piping main body, and the inside of the piping main body is capable of being viewed from an outside of the piping main body. The check plate is provided on an inner circumferential surface of the piping main body, is rotatably arranged side-by-side with the check window, droops by its own weight, and rises so as to block the check window in response to a pressure of the fluid.

Abstract: A connector for use in an ultra-high vacuum system is disclosed herein. The connector has a metal conduit section with a first hardness, a metal fitting with a second hardness greater than the first hardness, and a metallic reaction-inhibiting barrier positioned between the conduit section and the fitting to sealingly attach the fitting to the conduit section. In some embodiments, application of a mechanical stressor such as stretching or treatment with a mechanical oxide disruptor removes oxide from and prevents oxide re-formation on the faying surface of the conduit section. In alternate embodiments, oxide is removed from the faying surface of the conduit section and oxide re-formation is subsequently prevented by applying an oxide inhibitor. The reaction-inhibiting barrier substantially inhibits metallic and chemical interaction between the conduit section and the fitting under ultra-high vacuum, temperature cycling, mechanical stress, and reactive chemical conditions, as are present during manufacturing.

Abstract: A threaded connection partially in a self-locking arrangement includes a first and a second tubular component provided respectively with male and female threaded zone at their respective ends. Only a portion of a first portion with varying thread width of the male threaded zone cooperates by self-locking tightening with only a portion of the second portion with varying thread width of the female threaded zone when made up one into the other. The connection is able to withstand high torques required for special applications such as drilling with casing or intermediate casing.
