    Abstract: A plug valve having a modular construction. The valve has a solid, single-piece body with two opposed openings interrupted by an internal chamber. The chamber houses a rotatable plug which selectively restricts or allows flow from one of the two openings to the other. Inserts partially surround the plug and have openings that corresponds to openings in the valve body and the plug. A seat with an end surface corresponding to each insert extends partially within each opening. A bolted-on flange extends from each side of the valve and has an internally placed sleeve which defines the flow path through the valve. The sleeve may seal against the seat at one of its ends. A non-planar groove may be formed in the end surface of each seat to seal the opening against each insert.

    Abstract: A closure element for a fluid end assembly that has two or more recessed grooves formed in its outer surface. The grooves are axially offset. A seal is placed in one and only one of the grooves. As wear occurs, the seal is relocated to one of the other grooves. Instead of a series of axially offset grooves in a single closure element, a kit may be formed from two or more otherwise identical closure elements, each with a single recessed groove at a different axial position. Another closure element has a series of ledge-like surfaces defining spaces within which a seal may be received. One outer surface surrounds one or more of the other surfaces. A seal is placed in one and only one of the spaces. As wear occurs, the seal is relocated to one of the other spaces.

    Abstract: A fluid end with an internal bellows can be used in high pressure environments. The bellows is disposed within a plunger bore, and has an interior isolated from a working chamber of the fluid end. An end of a plunger is received in the interior of the bellows. The bellows contains an incompressible fluid at a constant volume. As the plunger extends into the interior of the bellows, the fluid it contains is displaced. Such fluid displacement causes the bellows to extend. As the plunger is retracted, the fluid replaces the volume formerly displaced by the plunger, and causes the bellows to accordion to a retracted position.

    Abstract: A high pressure swivel joint used in pipe assemblies transferring high pressure fluid. The swivel joint comprises a first pipe section and a sleeve-like second pipe section. The first pipe section is inserted into the second pipe section and the sections are relatively rotatable. A radial seal is seated in a groove formed in either the outer circumference of the first pipe section, or the inner circumference of the second pipe section. The groove is axially spaced from the location where the two pipe sections abut. Alternatively, a groove may be formed in both the outer circumference of the first pipe section and the inner circumference of the second pipe sections, the grooves both being axially spaced from the location where the two pipe sections abut. A radial seal may be inserted in both grooves and a wear ring positioned between the seals.

    Abstract: A pair of wear grooves for a linear drive assembly. One wear groove is disposed on a wear plate attached to a crosshead. This wear groove is on a front edge of the wear plate, and does not intersect any lubrication groove. Another wear groove is disposed circumferentially about an inner wall of a crosshead guide. Each of the wear grooves is observable to an operator without fully disassembling the crosshead and the crosshead guide, and each is observable from a single side of the crosshead guide. Should the wear groove not be observable, the associated component should be replaced. Should the wear groove be observable, the remaining life of the component can be determined from the groove's depth.
