Abstract: Aspects of the disclosure relate to fluid injection systems, apparatus, methods, and associated components thereof that include flexible hoses for wellhead sites. In one implementation, a fluid injection system for wellhead sites includes a platform, a pump manifold mounted to the platform, and a pair of rails mounted to the platform. The fluid injection system includes a trolley disposed between the pair of rails and above the pump manifold. The trolley is movable along the pair of rails. The fluid injection system includes an articulation arm device mounted to the trolley. The articulation arm device includes one or more pivot joints coupled between two or more arms, and a connection device coupled to an end arm of the two or more arms.

Abstract: Aspects of the disclosure relate to fluid injection systems, apparatus, methods, and associated components thereof that include flexible hoses for wellhead sites. In one implementation, a fluid injection system for wellhead sites includes a pump, a pump manifold, and a flexible hose coupled between the pump and the pump manifold. The flexible hose includes a first end coupled to the pump and a second end coupled to the pump manifold. The first end of the flexible hose includes a first end fitting coupled to the pump, and the first end fitting is oriented at an angle relative to a horizontal plane. The second end of the flexible hose includes a second end fitting coupled to the pump manifold, and the second end fitting is oriented vertically and perpendicularly to the horizontal plane.

Abstract: A plug valve is provided that may be lubricated while in service. The invention provides a high-pressure valve having a valve body containing a plug allowing bi-directional flow and moveable between an open and closed flow-through position. The valve permitting lubricating and sealing while in-service and in the closed or open position. The lubricating and/or sealing mechanism includes channels formed through the plug to a lubricant groove or grooves formed on the outside surface of the plug between the ends of the fluid conduit through the plug for directing lubricant to the plug-insert or plug-valve body interface when the plug is in the closed position and lubricant to the relief area formed by the insert when the plug is in the open position.
