Abstract: Seals for mechanical couplings and fittings have sealing surfaces with one or more projections that form closable leak paths between the coupling or fitting and pipe elements being joined. The leak paths close when the coupling or fitting is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings and fittings can be discovered during pressure testing and before service pressure is applied.

Abstract: An electrically grounded wear resistant liner is described that inserts into a conventional frac sand delivery conduit. The liner allows for conveyance of highly abrasive materials through the liner and conduit while electrically grounding potential static build up from within the liner. Sand, cement and other abrasive slurries may be conveyed through the liner. The wear resistant liner extends the amount of time that the conduit may be used to convey materials without downtime for replacement and repairs. The liner further provides a tri layer construction that includes a middle layer having a color notably different than the outer and inner layers, allowing a user in the fields to quickly determine that the conduit should be replaced.

Abstract: A drainage assembly (68) includes a first segment (70A) with a first inner tube (76A) defining a first inner tube passage (78A), a first outer tube (72A) concentrically disposed around the first inner tube (76A) and defining a first outer tube passage (74A), and a first fitting (80A) disposed on an end of the first segment (70A). The first fitting (80A) has a first inner passage (82A) in fluid communication with the first inner tube passage (78A) and a first outer passage (84A) in fluid communication with the first outer tube passage (74A). A plate (88) is positioned adjacent the first fitting (80A). The plate (88) has a second inner passage (90) in fluid communication with the first inner passage (82A) on one side, and a second outer passage (92) in fluid communication with the first outer passage (84A) on the one side. Also included is a drainage line (104) in fluid communication with the first outer tube passage (74A).

Abstract: Test flange assemblies comprise a flange body and a piston. The piston is configured to translate relative to the flange body and has an outer surface facing away from the flange body and an inner surface facing toward the flange body. The outer surface defines a circular seal channel for receiving a seal structure between the piston and a flange surface of a flanged component. The outer surface radially inward from the circular seal channel has a surface area that is less than a surface area of the inner surface. Methods of testing pressure containing structures comprise operatively positioning the test flange assembly, positioning a seal structure within the circular seal channel of the piston, coupling the flange body to a flanged component, and pressurizing a volume between the piston and the flange body so that the piston compresses the seal structure between the piston and the flanged component.

Abstract: A double containment fitting for connection to a double containment tubing system with an outer, secondary containment tubing surrounding an inner, primary tubing. The fitting includes a fitting body defining a central passageway, the fitting body having a center portion disposed between opposed first and second body ports. The fitting body is configured to receive the tubing system into the first body port. The central passageway has a diameter in the first port selected to allow the secondary tubing into the first body port. A connection system mechanically secures the secondary tubing to the first body port.
