In some implementations, a flowline connector assembly includes a first flowline member having a first cylindrical passageway, and a first stop extending radially outward from an outer surface of the first flowline member, and a second flowline member having an annular configuration defining a second cylindrical passageway. The flowline connector assembly may include a pin, having an annular configuration, configured to be inserted into the first cylindrical passageway and the second cylindrical passageway. The flowline connector assembly may include a collar where an inner surface of the collar at a first end is configured to contact a first side of the first stop, and the inner surface of the collar at a second end is configured to contact a first side of a second stop to connect the first flowline member with the second flowline member, where the second stop extends radially from the pin or the second flowline member.

A plug and pump system for routing pressurized fluid from a fluid source is disclosed. The system includes a platform and a docking station interface mounted on the platform and including multiple points of articulation. A wellhead interface is mounted on the platform and includes multiple points of articulation. The docking station interface and the wellhead interface are configured to route pressurized fluid from a fluid source.

A method of installing a coupling for joining pipe elements uses a pipe coupling having two segments with action surfaces in facing relationship. Attachment elements on each segment, in the form of lugs, accommodate adjustable fasteners which draw the segments together when tightened. Support surfaces on the lugs engage one another and react the fastener force. Stop surfaces are positioned on the lugs adjacent to the support surfaces. Engagement between the stop surfaces provides a visual indication that the coupling has been properly installed.

A v-clamp provides an enhanced axial load to tubular body end flanges in order to establish a fluid-tight joint therebetween. The v-clamp, according to an example, has a v-angle that varies in value over a section or more of a band of the v-clamp. The varying v-angle has been shown to effect an axial load that is more evenly and uniformly applied around a circumference of the v-clamp and to the underlying tubular body end flanges. Furthermore, in an example, the tubular body end flanges have a partially spherical shape.

A fire suppression sprinkler adapted to receive arcuate surfaces of a grooved coupling is retainable to the coupling in a pre-assembled state. The coupling joins the sprinkler in facing axial end to end relation directly to grooved pipe. The sprinkler has a monolithic body which defines a bore having an inlet and an outlet. A groove, positioned between the inlet and the outlet extends around the body. A projection, positioned between the groove and the outlet also extends around the body.

Clamping system for connecting two tubes having protruding clamping surfaces. The system comprises a collar having a strip able to cooperate with the clamping surfaces. The strip has a first and a second flank between which an inner recess able to receive the clamping surfaces is delimited. The system has at least one retaining clip having a cross-member which extends across the inner recess, a first and a second wing which extend radially outwardly relative to the cross-member by covering the flanks and a first and a second retaining configuration each having at least one retaining lug. The cross-member is able to be deformed to penetrate into the inner recess.
