Abstract: A fitting for joining pipes, tubes, or conduits improves coupling capability particularly to a large bore pipe, generally of 2 inches and larger in diameter. The fitting includes a substantially cylindrical sleeve and ring. The sleeve has an inner surface defining a bore, configured to slidably receive the pipe at an open end. The inner sleeve surface also includes protrusions, which deform the outer surface of the pipe upon swaging. The fitting also includes an outer surface having multiple stepped lands of ascending height relative to the open end. The ring has an inner surface configured to engage the multiple ascending steps on the inner sleeve surface. The inner surface of the ring has descending steps that are positioned to interfere with the multiple ascending steps on the outside of the sleeve. Axial motion of the ring causes the ring to slide over the sleeve and apply a radial swaging force directly to the multiple stepped sleeve.

Abstract: A production swivel with passive control of dynamic seal gap width using internal swivel pressure. The swivel includes inner and outer housings with a middle housing which transfers, component deformation due to fluid pressure from the dynamic sealing interface to the static sealing interface. The outer housing and inner housing rotate together, but the outer housing is free to expand radially outward from the middle housing with increasing fluid pressure. A floating riser spool is pressure balanced at the connection to the inner housing and to a fixed swivel stack base. Swivels are stacked with a swivel connector/spool and upper and lower mounting rings cooperatively dimensioned so that access to seals can be obtained while the swivels remained stacked without the use of overhead cranes or other lifting points than the swivel being serviced.

Abstract: An insert section of an insert member is inserted into a tube member in a state in which the insert member is detached from a recess to form a diametrally expanded section on the tube member. Subsequently, the insert member is fitted to the recess to install the tube member to the recess. At this stage, an outer circumferential surface of an expanded section of the insert member tightly contacts with an inner circumferential surface of the recess to effect the sealing function. Subsequently, a tapered section and an outer circumferential surface of the tube member are resin-welded by using a welding material. Thus, the tube member is prevented from disengagement from a body.

Abstract: The invention is to provide a coupling structure of corrosion resistance for nonferrous metal piping.

Abstract: A pipe coupling according to the invention comprises a socket (2) of glass-fiber reinforced plastics material and a membrane (4) of elastic material which is formed at at least one end as a seal and comprises a sleeve section (8). Where the membrane is formed as a seal, it has at the end where the pipe (20) is to be introduced (thus at the outer end), a short cylindrical band (14). In the cylindrical band the membrane has a constant wall thickness, which is backed by the glass-fiber reinforced socket material of the pipe coupling.

Abstract: A spring retainer clip used with a quick-connect coupling for coupling a male connector having an outwardly extending protrusion in a bore of a female connector having an inwardly extending protrusion wherein the outwardly and inwardly extending protrusions are separated by an annular gap. The spring retainer clip comprises a ring having an axially extending collar for fitting around the male connector and a radially extending base unitary with the collar. A plurality of spring arms, unitary with and extending axially from the radially extending base, have transverse T-bars at free ends thereof adapted to extend through the gap between the protrusions and block movement of the protrusions past one another. Consequently, the male and female connectors cannot be separated if the width of the gap is substantially reduced.

Abstract: A locking telescoping joint is for use in a conduit connected to a wellhead, which permits the conduit to be axially displaced to a new position in the well bore without disconnecting the conduit from the wellhead, and secured in the new position. The locking telescoping joint includes two telescopically interconnected tubular sections which are relatively movable between a fully retracted and a fully extended position and can be locked in a desired position. In contrast with telescoping joints without the locking function which is useful to axially display downhole tools attached to the bottom end of the conduit. The locking telescoping joint enables the use of the telescoping joint to be extended into new applications, such as placing and maintaining a tubing string in tension or compression. The use of the locking telescoping joint reduces the time and cost of many well completion and maintenance operations and thereby reduces the cost of producing hydrocarbons.

The come-out preventing member and the engaging member are respectively provided with first engaging portions and second engaging portions to engage the come-out preventing member and the engaging member to each other and to prevent the first and second tube members from being separated.

Abstract: A plastic mounting ring comprises two plastic arcuate members each having a flat upper profile, a flat lower profile and a predetermined thickness. Each plastic arcuate member has a lip extending radially inwardly with an inside diameter that allows it to engage the sides of the channel formed by the flange on the water closet coupling on which it is to be mounted. A corresponding first end of each arcuate member has a notch out of the lower level of its thickness. A second corresponding end of each arcuate member has an extension, coplanar with its flat lower profile, which engages the lower surface of the base of the opposite end of the other arcuate member. The members are fitted together to form a mounting ring having a flat upper profile and a flat lower profile. The mounting ring can be used to replace a flange formation of an installed water closet coupling without removing the total water closet coupling.
