    摘要： A coupling includes a male adapter and a female adapter, and may include a nut and a sleeve. In embodiments, the male adapter includes a male adapter inner diameter, and may include threads. The female adapter includes a female adapter outer diameter. The nut or other formation may be configured to engage at least a portion of the male adapter. In embodiments, one or more contact points may be provided between the female diameter outer diameter and the male adapter inner diameter, and the female adapter outer diameter or the male adapter inner diameter may be configured to be out-of-round. The male adapter may include a shoulder and the sleeve may cover the shoulder in connected configuration. Methods for forming a coupling are also disclosed.

    摘要： A coupling arrangement for a screw coupling for liquid conduits of a high-pressure cleaning apparatus is provided. The coupling arrangement includes a plug part which is pluggably connectable to a complementarily configured plug part of a second coupling arrangement of the screw coupling for establishing a liquid-tight and releasable connection therewith with a sealing ring interposed therebetween, and a connecting part having a thread that is screwably connectable to a complementarily configured thread of the second coupling arrangement. The thread can be of multiple-threaded configuration and the connecting part can include a clamping element which is aligned in an in-line relationship with the thread relative to the thread longitudinal axis and is releasably clampable against a complementarily configured clamping element of the second coupling arrangement by axially inserting one into the other.

    摘要： A pipe joint, made of synthetic resin, including: an inner ring; a joint body having an annular sealing groove and a male screw portion formed on an outer circumference; a union nut having a female screw portion formed on an inner circumference to be tightened onto the male screw portion of the joint body, such that a first opposing surface is formed in the joint body to be perpendicular to an axial direction, and a second opposing surface is formed in the union nut to oppose the first opposing surface. An engagement projection is provided in one of the first opposing surface and the second opposing surface. An engagement recess is provided in the other of the first opposing surface and the second opposing surface such that the engagement projection engages with the engagement recess when the union nut has been tightened up to an appropriate position.

    摘要： A quick disconnect coupling for connecting a tube to another structure, such as a structure defining a port. The quick disconnect coupling may include a tube including a retention shoulder, a swivel rotatably disposed on the tube, and an adapter defining a bore for receiving a portion of the tube. The swivel may be engageable with the adapter to trap the retention shoulder between the swivel and the adapter. The adapter may be engageable with a receiving structure defining a port and the port may be in fluid communication with a lumen of the tube when the swivel is engaged with the adapter.

    摘要： A connection verification tool for verifying a secure connection between two fluid handling components of a fluid handling system. A connection verification tool can include a gauge portion sized sized to be placed over a first fluid handling component connected to a second fluid handling component to verify a secure connection between the two components. If the first fluid handling component is not securely connected to the second fluid handling component such that additional torque may be required to complete the connection between the two components, the gauge portion of the connection verification tool will not fit over the first component coupled to the second component.

    摘要： The present invention provides a novel clutch connector assembly for jointed pipe, threaded pipe, coiled tubing or any threaded or non-threaded pipe for a bottom hole assembly that eliminates the need to use screw threads to mate two pipes or mechanical assemblies, harbors a spring-loaded mechanical locking system in addition in to a pressure-activated, component protectant system, requires no significant tools, other than an Allen wrench or similar screw setting device, permits distributed torque loading, allows for movement in either a clockwise or counter clockwise rotational direction through interlocking castellations and presents a removeable and replaceable valve assembly preventing retrograde hydrocarbon advancement through a drilling pipe.
