The disclosure presents systems and methods for hot swapping pumps at a wellsite while minimizing the impact to the pumping operations. As one pump is swapped out, such as for maintenance, the remaining pumps in the set of pumps at the wellsite can continue pumping operations. In some aspects, the swapping of pumps can be performed by a user using a protection barrier to isolate the pump location where the pumps will be swapped. In some aspects, one or more of the steps to swap pumps can be performed through automation thereby minimizing danger to a user. In some aspects, the pump being located at the pump system can be primed and pressure tested prior to be located to improve the time to enable the pump for pumping operations.

Devices and methods for reversibly securing first and second component subs of submersible well pump assembly. First and second component subs are provided with connection end portions which are placed into a sealed abutting relation. A connecting collar is threaded onto the first component sub. A locking groove on the first component sub receives a locking dog therein.

A breech lock coupling comprising a stem receivable in a hose, a ferrule configured to receive the stem and hose, a connector, the ferrule comprising a plurality of ferrule lugs on an inner surface, each ferrule lug separated from an adjacent ferrule lug by a ferrule lug gap, the connector comprising a plurality of connector lugs on an outer surface, each connector lug separated from an adjacent connector lug by a connector lug gap, each ferrule lug gap arranged to receive a connector lug and each connector lug gap arranged to receive a ferrule lug upon engagement of the ferrule with the connector, each connector lug axially alignable with a ferrule lug upon rotation (R) of the connector within the ferrule, the connector engages a stem end, a fastener for fixing a connector position relative to the ferrule.

A fluid line support system includes a fluid line and a collet having an insertion end and a thickened portion having a biased end. A fluid valve has a valve aperture that receives the insertion end of the collet. A collet securing device has a fluid line portion that engages the wall of the fluid line, wherein at least the fluid line portion encircles the wall and is slidably engaged with the wall to define a loose position and a securing position. A collet portion of the collet securing device engages the retaining portion of the fluid valve when in the securing position. When in the securing position, the fluid line portion engages the biased end of the collet, wherein the fluid line and collet portions bias the retaining portion and biased end toward one another such that the insertion end is positioned at a final insertion depth.

A pipe coupling system includes first and second polymeric, thermoplastic pipes secured to each other by a pipe coupling. The pipe coupling includes a mechanical sealing surface adapted to receive a mechanical seal, a fusion seal, or both. The pipe coupling includes a pipe coupling body with an outer surface and a first end and an oppositely positioned second end. First and second respective threads are respectively defined about the first and second ends. A nut is used in the pipe coupling system when the mechanical seal is used to join the pipe first ends to seal against the coupling inner surface. A mechanical capture ring is also included, which defines a central aperture having inwardly angled engagement prongs that are sized to capture the respective first ends of the pipe. The engagement prongs are configured to each include a sloping face.

A conduit connection system may have a first coupling connected to a first conduit. The first coupling may have a first undercut. The conduit connection system may also have a second coupling connected to a second conduit. The second coupling may have a second undercut. The conduit connection system may have a clamp. The clamp may have a first projection. The first projection may be configured to be received in the first undercut. The clamp may have a second projection. The second projection may be configured to be received in the second undercut. The conduit connection system may also include a connector. The connector may be configured to engage with the clamp to connect the first coupling and the second coupling.

Insertion fitting/coupler devices for coupling to a flowpath, and methods of using such insertion fitting/coupler devices, are disclosed. The insertion fitting/coupler devices include a coupler that includes a through hole and a stem portion. The insertion fitting/coupler devices also include a nut that includes a through hole, a rim and a body portion. The insertion fitting/coupler devices further include a body member that includes a through hole and an outer flange. The body member extends into the through hole of the coupler such that an end of the stem portion of the coupler engages the outer flange of the body member. An inner side of the body portion of the nut engages with an outer surface of the stem portion of the coupler such that the flange is secured between the rim of the coupler and the end of the stem portion of the coupler.
