摘要： The premium threaded tubular connection comprises, on at least one threaded element, a distal abutment surface (7) at the free end of a threaded element and a lip sealing surface (5) at a given distance from the threading. The lip comprises an appendix (13) which extends the lip towards its free end beyond the lip sealing surface (5) so that the lip has both high radial stiffness and low axial stiffness. This results in enhanced performance as regards the seal of the threaded connection under pressure and/or under tension, and in other advantages (precision of real makeup torque, mechanical strength in axial compression, a shock barrier effect, tolerance in engaging the threaded elements).

摘要： A device for prevention of particulate contamination of a valve fitting and for notification of whether actual access or tampering or potential access or tampering of a fluid from a fluid tank connected to the valve and/or the valve has occurred, featuring a fitting block which is insertable within the fitting or capable of receiving the fitting, and first and second straps bendable about the valve and fastenable to each other. One of the straps may include a ring through which a valve burst disk is insertable when the strap is bent about the valve. If the device was compromised and the cylinder was removed for access to the valve fitting, the ring of one of the straps would remain on the burst disk even though the cylinder was removed from the fitting. Thus, the compromised device would remain on the valve indicating that access to the valve or fluid had been attempted or achieved.

摘要： A riser assembly includes riser segments, each having threaded ends. A coupling nut is connected to the threaded end of the first riser segment. The threads of a second riser segment and a set of corresponding threads of the coupling nut are breech threads, which allow the second riser segment to stab into the coupling nut and engage the first riser segment. The coupling nut rotates a portion of a turn in order for the breech threads of the second riser segment and the first riser segment to engage each other. Castellations on the first and second riser segments engage each other to transmit torsional forces from one riser segment to the other instead of through the threads.

摘要： A leak testing device to be positioned between two adjacent conduits comprises a generally cylindrical body defining a recess therethrough and including first and second end portions for cooperating with the respective end portions of two adjacent conduits. The body includes an opening between the first and second end portions. A sealing door is provided to be positioned in the opening. A diaphragm member including a through hole is provided to be positioned within the body. A valve is operably connected to the diaphragm member for selectively opening or closing the through hole to thereby permit or restrict the flow of a fluid between the two conduits. The opening in the body receives the diaphragm member when leak-testing a conduit, or the sealing door when connecting the two conduits in a fluid communication.

摘要： A threaded tubular connection has a box member including an internal thread, a pin member including an external thread engageable with the internal thread of the box member, and a protruding sealing surface disposed in the box member such that the pin member flexes radially inward upon passing the protruding sealing surface during make-up. The threaded tubular connection also has a recessed seal cavity disposed in the box member and a reverse angle shoulder at the pin nose that forces the pin member to flex radially outward into the recessed seal cavity of the box member upon final make-up. A method of forming a double flex seal for a tubular connection includes engaging an internal thread of a pin member with an external thread of a box member and flexing a pin nose of the pin member radially inward by passing the pin nose over a protruding sealing surface of the box member during make-up. The method also includes flexing the pin nose radially outward when a reverse angle shoulder of the pin nose comes into contact with a reverse angle shoulder of the box member during make-up and completing the double flex seal by finally making up the connection such that the pin nose of the pin member seats in a recessed seal cavity disposed in the box member.

摘要： A force absorbing restraining system for a number of pipe sections, each having an integral restraining system which is subsequently connected and works in conjunction with the integral restraining system of adjacent pipe sections. It is known that during an explosive failure either of a pipe section or a joint between pipe sections, a tremendous amount of reaction force is generated by escaping effluent flow. This force, in turn, may energize equipment such as pipes, pumps, and the like to exhibit uncontrolled motion often at a rate of several hundred feet per second. The restraining system of the present invention is designed to absorb a sudden burst of explosive energy and to lessen the reaction forces generated by the explosion so as to ensure that equipment does not move about a service site in an uncontrolled manner which could injure people and damage buildings or other equipment. In short, the force absorbing restraining system in accordance with the present invention reduces the effects of impact loading during explosive failure by dissipating energy in the permanent mechanical deformation of an integral restraining tube assembly attached to each pipe section.

摘要： A coupling assembly includes a female member having a receiving end with an axially extending passageway and inwardly facing groove extending outwardly from said passageway in a position spaced from the receiving end. A split metal locking ring is positioned in the groove. A male member is sized to be received in said receiving end and includes a rib having a ramp where the ramp in a first embodiment curves outwardly to an apex and in a first alternate embodiment curves outwardly to a flat and in a second alternate embodiment increases in height in a linear fashion until a relatively short distance from the flat where it curves outwardly to meet the flat, the rib also has a shoulder tapering away from the forward end and inwardly toward the axis. Upon insertion of the male member into the female member, the split metal ring is expanded as it rides over the ramp, engages the cylindrical surface and retracts to a smaller diameter approaching its original size to engage the shoulder thereby locking the male member into engagement with the female member. A release sleeve is mounted on the male member and is axially movable relative thereto to push the split locking ring up and off of the tapering shoulder to thereby disengage the male member from the female member.

摘要： A method for forming an integral socket to a pipe made from biaxially oriented thermoplastic material is described. The pipe has a pipe body and is provided, at one or both ends, with an integral socket. The biaxially oriented thermoplastic pipe is subjected to a socket-forming operation comprising the steps of fixing both axial ends of the unheated end part of the pipe, heating the fixed end part to a suitable socket-forming temperature in one or more steps, and expanding the axially fixed end part with the aid of a fluid pressure in the interior of the end part and/or a vacuum on the outer side of the end part, which expansion may begin as early as during the heating of the end part.

摘要： Apparatuses and methods for connecting and disconnected fluid conduits (e.g. medical tubing) are disclosed. Typical embodiments of the Apparatuses and methods disclosed herein operate with two separate components, the first having a moveable septum and the second having a fixed septum. When the components are engaged, the device allows the flow of fluid through a conduit to which they are coupled. When the components are uncoupled, the device prevents the flow of fluid through the conduit. An exemplary embodiment of the invention includes a housing, a moveable septum slideably coupled with the housing to be alternately disposed in at least a first and second position and a piercing member having a passage for conducting fluid. The moveable septum closes the passage in the first position and is penetrated by the piercing member to open the passage in the second position.
