Abstract: A lock pin bore in a two-step rocker arm assembly contains a hydraulically-actuable lock pin. A return spring urges the lock pin toward an unlatched mode. The bore has one or more annular grooves formed near the outer end of the bore. A plug, formed preferably of a soft metal, is pressed as a hydraulic seal into the bore. During assembly, the final position of the lock pin within the bore is set by positioning a stopping assembly fixture into the locking end of the bore. The plug is pressed into the bore until contact is made with the lock pin and the lock pin engages the fixture. The plug is radially deformed into the annular groove(s) to anchor the plug and fix the outer limit of travel of the locking pin and the compressive load on the return spring.

Abstract: A plug assembly for a tube includes a tapered wedge and a sleeve. The sleeve fits over the wedge and is placed in a tube. Relative movement of the wedge and the sleeve causes the sleeve to expand and plug the tube. The exterior surface of the wedge and the interior surface of the sleeve include annular grooves. One or more compression rings in either the grooves in the sleeve or wedge permit motion of the sleeve relative to the wedge only toward the large diameter portion of the wedge. This prevents the sleeve from separating from the wedge after being installed in a tube.

Abstract: An assembly mating first and second tubular bodies is disclosed. The mating assembly includes at least a sleeve structure forming a part of the first tubular body and defining an inner receptacle surface region, a compression loading assembly integrally formed with, constituted by, or otherwise securable to the second tubular body and at least partially received in the sleeve structure, and a cured adhesive bond positioned between an exterior surface region of the compression loading assembly and the inner receptacle surface region to couple the sleeve structure to the compression loading assembly. The compression loading assembly is laterally expandable at at least the exterior surface region thereof and constructed and arranged relative to the cured adhesive bond so that expansion of the exterior surface region compressively loads the cured adhesive bond in a substantially lateral direction. The strength of the adhesive bond is thereby increased against shear stresses acting on said mating assembly due to longitudinal and/or torsional loading.

Abstract: Tube plug and method for plugging a heat exchanger tube having an inner wall, which tube plug has a reduced susceptibility to stress corrosion cracking. The tube plug includes a shell having a closed end, an open end and an outer wall, the shell defining a chamber therein in communication with the open end of the shell. Disposed in the chamber is an expander member for expanding the outer wall of the shell into sealing engagement with the inner wall of the tube. A sealing member engages the expander member and is disposed across the open end of the shell for sealing the chamber defined by the shell so that fluid can not enter the chamber to corrosively attack the shell.

Abstract: A well-head (W) having a casing (C) through which a fluid flows. Apparatus (10) for controlling the flow of fluid has an output shaft (14) insertable into a sleeve (18), sleeve (18) being insertable into the casing at its fluid outlet end (E). The sleeve extends from a hub (12) which is placeable into the outlet end of the casing and extends down into the casing. The output/draw shaft (14) extends up through the sleeve, and has a draw nut (34) and a shut-off valve (16). The valve (16) allows fluid flow through the output/draw shaft during installation of the sleeve but shuts off flow thereafter. The sleeve has a circular wall (22), defining a longitudinal bore (24) having an inner diameter (D1) which gradually increases from the upper to the lower end of the sleeve. Circular wall (22) thus has a tapering thickness along the length of the sleeve. The output/draw shaft (14) is inserted up through the sleeve and has a tapered external diameter corresponding to the internal taper of the sleeve. The output/draw shaft is drawn upward inside the sleeve, by tightening the draw nut, thereby forcing the wall of the sleeve to expand outwardly and adhere to the inside of the casing.

Abstract: A plug retainer for a tube plug. The plug head and inboard end of the plug are captured by a locking cup and cap screw. The locking cup is threadably engaged in the open end of the tube plug. The cap screw shank extends through a bore in the locking cup and is threadably engaged with the mandrel in the tube plug. Compression rings on the locking cup and cap screw seal the locking cup to the tube plug and the cap screw to the locking cup to prevent leakage. The locking cup is crimped on the cap screw by the use of flutes on the cap screw head.
