Abstract: A hydraulic coupler for providing fluid communication between adjacent members that includes a two way check valve formed from a double headed poppet set in a hollow cylinder with corrugated bellows like walls. Contoured bores are provided in the cylinder ends and the poppet heads are profiled to match the contour of the bores. When the heads are seated in the bores they form a sealing surface to block fluid from flowing through the coupler. Compressively preloading the cylinder before assembly provides a sealing force between the heads and the bores. Axially compressing the cylinder with respect to the poppet unseats the heads from the bores to form a flow path through the coupler.

Abstract: A stiffened mandrel used in the manufacture of a composite tubular. The mandrel is placed on a filament winding machine and is comprised of an outer and inner shell. A pressure source is connected to the mandrel to exert a tensile force on the outer shell to stiffen the mandrel and thereby prevent sagging and bending of the mandrel. The stiffened mandrel allows for the manufacture of a composite tubular without undesirable flexing, wrinkling, or contamination of the uncured composite.

Abstract: A device for mechanically securing a tubular liner in a pipe having a tubular member and connectors on each end. The connector has a bore with an internal seat that may have grooves and be tapered depending upon the application. The liner extends through the tubular member into the bore. The ends of the liner are radially and plastically deformed into engagement with the seats. An inner ring is positioned inside the liner to retain the end of the liner in engagement with the seat. The inner ring may be held by threads or by radially and plastically deforming it. The connectors are mounted to the tubular member independently of the liner, such as by adhesive. The liner may be replaced by removing the inner rings without affecting the connection between the tubular member and the connectors.
