A swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and particularly suited to the petrochemical and drilling industries. Two embodiments of the connector for use with wire reinforced thin internal tube hose are disclosed: one with a diameter of 3-inches and for burst pressures up to 20, 000 psi and the other for a diameter of 5-inches and for burst pressures up to 18,000 psi. All of the connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the device will fail before the connector pops off the hose. The connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006.

The invention relates to a system for connecting rigid pipes and for connecting flexible pipes. The pipes have corresponding outer diameters, with a press jaw having a press contour, with at least one first fitting for press-fitting to a rigid pipe, the at least one first fitting having a first press sleeve with a first outer contour, with at least one second fitting for press-fitting to a flexible pipe, the at least one second fitting having a second press sleeve with a second outer contour, the at least one second fitting having a second press sleeve with a second outer contour has a second press sleeve with a second outer contour, the outer contour of the first press sleeve and the outer contour of the second press sleeve in each case being adapted at least in sections to the press contour of the press jaw of the press jaw and can be pressed by the press jaw and wherein the outer contours of the first press sleeve and of the second press sleeve correspond at least in sections. This system solves the technical problem of simplifying the on-site effort for installing piping systems. In particular, the task is to specify suitable combinations of fittings for rigid and flexible pipes

A press fitting for a pipe connection is provided. The press fitting comprises a fitting body for connecting the press fitting to a pipe, a substantially cylindrical pressing sleeve fixed to the fitting body and having a pressing area, and a stop ring fixed to the pressing sleeve and limiting the pressing area in an axial direction of the press sleeve. The stop ring has a substantially cylindrical inner contour with protruding first regions and second regions receding from the first regions. The first areas of the first stop ring encompass an outer contour of the pressing sleeve in a clamping manner. The second areas of the stop ring are spaced from the outer contour of the pressing sleeve.

A fitting assembly for fitting a first tube element to a second tube element comprising a fitting element defining a longitudinal axis and comprising a male portion adapted to engage the first tube element and a female portion adapted to be engaged by the second tube element; the female portion being opposite to the male portion along the longitudinal axis and further defining a seat; a bushing element adapted to be arranged radially external with respect to the male portion and the first tube element and to exert a radial compression on the first tube element; and a locking element adapted to limit the relative movements of the second tube element with respect to the fitting element when it engages the seat.

A connect structure for semiconductor processing equipment includes a housing configured to mate a deformable pipe with a non-deformable pipe. The housing includes a first annular sidewall to receive the deformable pipe and a second annular sidewall defining a first thread structure. An annular bead is connected to the first annular sidewall to flexibly deform the deformable pipe toward the non-deformable pipe structure when the first thread structure rotatably engages a second thread structure of the non-deformable pipe.

A rinse device comprising a housing part and a rinse hose, the housing part having a first end configured to be attached to a supply of pressurized fluid and a second end to which a first end of the rinse hose is attached, a second end of the hose is open to allow fluid to flow out of the hose, in use; the housing part defining a cavity through which pressurized fluid from the supply flows, in use, from the first end to the rinse hose, the rinse hose being a flexible and extendible hose provided with a plurality of openings through which the pressurized fluid is ejected; and wherein the rinse hose comprises an elongate tube through which the fluid flows, in use, the openings provided through the elongate tube.

A breech lock coupling comprising a stem receivable in a hose, a ferrule configured to receive the stem and hose, a connector, the ferrule comprising a plurality of ferrule lugs on an inner surface, each ferrule lug separated from an adjacent ferrule lug by a ferrule lug gap, the connector comprising a plurality of connector lugs on an outer surface, each connector lug separated from an adjacent connector lug by a connector lug gap, each ferrule lug gap arranged to receive a connector lug and each connector lug gap arranged to receive a ferrule lug upon engagement of the ferrule with the connector, each connector lug axially alignable with a ferrule lug upon rotation (R) of the connector within the ferrule, the connector engages a stem end, a fastener for fixing a connector position relative to the ferrule.

A piping includes: a hose made of an elastic material; a pipe made of metal, the pipe having an insertion part inserted inside of the hose; and a sleeve arranged on an outer side of the insertion part and the hose in a radial direction. The insertion part has an uneven surface around an outer circumference side of the insertion part, and the uneven surface has an annular groove and an annular projection. The groove has a groove slope that narrows the pipe toward a tip end of the insertion part, and a groove bottom that extends from an insertion-tip-side end of the groove slope to the projection with a constant outer diameter. The sleeve has a small diameter part located on an outer side of the uneven surface in the radial direction to press the hose against the uneven surface.

A fitting (30) for fluid communication with a fluid conduit includes a first fluid conduit connection portion (42), a second fluid conduit connection portion (42), a header (60) disposed axially between the first fluid conduit connection portion and the second fluid conduit connection portion, and a socket (70). A fluid fitting may include a nipple (40), a radial projection (48) connected to the nipple, and an axial protrusion (120) extending from the radial projection. The axial protrusion may be configured to protrude into an axial end of a fluid conduit (80). A fluid fitting may include a fluid conduit connection portion (42) and a dynamic tip (130) connected to an end of the fluid conduit connection portion. The dynamic tip may be configured to expand in response to an increase in fluid pressure.

Methods of making hose fittings include providing a stem having a fluid conduit, a first end, a second end with a raised shoulder, and a threaded region disposed between the first end and the second end. Further, the stem may include barbs for sealingly engaging an inner diameter of a hose. A swivel tube nut is then placed over the stem, and the swivel tube nut is retained on the stem the by the raised shoulder. A ferrule is thereafter placed over the first end of the stem, and the ferrule comprises a partially formed hexagonal wrench surface, formed prior to. The ferrule also includes female threads corresponding to male threads on the stem. The ferrule is screwed onto the stem and secured thereon via the hexagonal wrench surface.
