摘要： A threaded tubular connection has a box member (29) including an internal thread (42), a pin member (28) including an external thread (27) engageable with the internal thread of the box member (29), and a protruding sealing surface disposed in the box member such that the pin member (28) flexes radially inward upon passing the protruding sealing surface during make-up. The threaded tubular connection also has a recessed seal cavity (48) disposed in the box member and a reverse angle shoulder (40) at the pin nose that forces the pin member (28) to flex radially outward into the recessed seal cavity (48) of the box member (29) upon final make-up.
A method of forming a double flex seal for a tubular connection includes engaging an internal thread of a pin member with an external thread of a box member and flexing a pin nose of the pin member radially inward by passing the pin nose over a protruding sealing surface of the box member during make-up. The method also includes flexing the pin nose radially outward when a reverse angle shoulder of the pin nose comes into contact with a reverse angle shoulder of the box member during make-up and completing the double flex seal by finally making up the connection such that the pin nose of the pin member seats in a recessed seal cavity disposed in the box member.

摘要： A rotating diverter (108) for isolating fluid in a well (30) from other fluid above the well (30) is provided. The rotating diverter (108) includes a housing body (162) which has a bore (168) running through it. A retrievable spindle assembly (178) which includes a spindle (178) and a bearing assembly (184) is disposed in the bore (168). The bearing assembly (184) supports the spindle (178) for rotation. The spindle (178) is adapted to receive and seal around a tubular member, and rotation of the tubular member rotates the spindle (178) within the bore (168). A lock member (176) is disposed in the housing body (162) to secure the retrievable spindle assembly (178) to the housing body (162).

摘要： Resin impregnation of fiber bundles for use in making a composite material is described. The improvements of the disclosed method and impregnation head enable high fiber take-off speeds without excessive damage or fraying of the fiber bundles. Encapsulated air or voids in the impregnated product are consistently less than 1 % by volume of the impregnated product and decrease with increased take-off speed. These improvements are achieved by passing the fiber bunbles (40) through a multi-chambered impregnation head (10) in which the resin is injected into a downstream chamber (28). The cross-sectional area of the fiber bundles, the velocity of the fiber bundles, the size of the openings to the chamber, the viscosity of the resin and the pressure at which the resin is pumped into the downstream chamber all control the pressure within the downstream chamber. The pressure is adjusted so that the resin flows upstream against the movement of the fiber bundles and sets up a wall of resin in the upstream chamber (26). The wall of resin minimizes the air that is encapsulated with the resin and prevents air from entering the downstream chamber. The pressures and counter flow of resin within the impregnation head drives encapsulated air out of the resin.

摘要： A threaded pipe connection is disclosed for connecting two joints of pipe having externally threaded pin members (10, 12), one pin member (10) having external right-hand threads (14) and the other pin member (12) having left-hand threads (16). An internally threaded coupling (18) having right and left-hand threads (20, 22) that mates with the threads (14, 16) on the pin members (10, 12). An internal pressure seal ring (23) is positioned to provide a seal between the ends of the pin members (10, 12). A plurality of mating lugs (24) and grooves (26) on the ends of the pin members (10, 12) hold the pins from relative rotation when the connection is being made up. A metal-to-metal seal located between each pin member (10, 12) and the coupling (18) adjacent each end of the coupling (18) isolates the threads of the connection from the ambient environment thus sealing off the pipe annulus from external pressure due to hydrostatic head. Indicia such as engaging surfaces (24a, 26a) or aligned scribe lines on the pin members (10, 12) ensure that the sealing surfaces (28, 29, 30, 31) on the coupling (18) and the pin members (10, 12) that form the external seals are positioned to properly engage and form seals when the connection is made up.

摘要： The same size and weight of tubular products, but in different grades of material, are made for universal connection but with seal areas that differ appropriately for adequate sealing without overstressing the connection members for the pressures encountered where each tubular length is put in service. The angle of the conically tapered seal on all box members (7) is made the same for all grades of the products. The pin member (10) of medium grade is made with an equal length seal area (16) and adjacent contacting area (11) on its forward end. The pin member (10) of higher grade is made with a longer length seal area than its adjacent contacting area. The pin member of lower grade is made with a shorter length seal area than its adjacent contacting area, thereby also placing the seal area further from the pin member distal end. This effectively forms a nose extension on the pin member (10) which stiffens the pin member (10) of lower grade and enhances the conical seal area forward of the first thread, which seal is spaced at a distance from the distal end by a non-sealing nose extension that is at least as long as the sealing area. The integrity of the seal is improved, the bearing surface is enlarged and the tendency of galling is reduced.

摘要： On fabrique des produits tubulaires de mêmes taille et poids mais dans différentes qualités de matériau, pour un raccordement universel, avec des surfaces d'étanchéité différant de manière appropriée, afin de permettre une étanchéité adéquate sans soumettre à un effort excessif les éléments de raccordement, pour les pressions rencontrées là où chaque élément de raccordement est mis en service. L'angle du joint conique sur tous les éléments femelle (7) est le même pour toutes les qualités des produits. L'élément mâle (10) de qualité moyenne a une surface d'étanchéité (16) et une surface de contact adjacente (14) d'égale longueur. L'élément mâle (10) de qualité supérieure a une surface d'étanchéité plus longue par rapport à sa surface de contact adjacente. L'élément mâle de qualité inférieure a une surface d'étanchéité de longueur plus courte par rapport à sa surface de contact adjacente, ce qui place également la surface d'étanchéité plus loin à partir de l'extrémité distale de l'élément mâle. Cela a pour effet de former une prolongation en forme de nez sur l'élément mâle (10), rigidifiant l'élément mâle de qualité inférieure et augmentant la surface du joint d'étanchéité conique en avant du premier filetage. Ledit joint d'étanchéité est espacé à une certaine distance de l'extrémité distale par un prolongement en forme de nez non étanche, qui est au moins aussi long que la surface d'étanchéité. Ainsi on améliore l'intégralité du joint d'étanchéité, on élargit la surface de support et on réduit la tendance au grippage.
