Abstract: A method of joining a tubular member and a pipeline configured to convey corrosive products comprises preparing a tubular member with an inner seat; inserting the end of a pipeline inside the inner seat; inserting a sleeve of corrosion-resistant material inside the end of the pipeline; inserting an expandable mandrel inside the sleeve; and expanding the expandable mandrel to join the end of the pipeline and the tubular member, and seal the sleeve and the pipeline to protect parts of the pipeline, sensitive to corrosive products, via the sleeve.

Abstract: A balloon holder includes a cup portion having a stem with a barb extending therefrom, and a conical cup defined by a sidewall extending from the stem to define a top edge of the conical cup. The balloon holder further includes a stick portion including an elongate stick body extending from a first end to a second end, a stem receptacle at the first end, and a barb receptacle provided in the stem receptacle, wherein a portion of the stem is received in the stem receptacle such that the barb locks into the barb receptacle to join the cup portion and the stick portion together to form a complete balloon holder.

Abstract: A connecting system connects two fluid-conducting components, such as first and second tubes, or a tube and a connecting part, or first and second pipes. The connecting system includes: a flange of a first component set back from a free end region of the first component; a flange of a second component formed at or behind a free end region of the second component; a securing device that engages a sleeve arranged at the second component so as to axially secure and align the first and second components with respect to one another; and a jacket that at least regionally covers the first component, the second component, and the securing device.

Abstract: An apparatus for preventing hose barb leaks, blowouts, and damages contains a hose barb, a bumper, and a band clamp. The hose barb has a double configured hose barb serration arrangement for preventing leaks and blowouts. In particular, the hose barb has a pair of reverse-angled serrations and a plurality of secondary serrations. Additionally, the hose barb also includes a first threaded portion and a shaft portion. The first threaded portion engages to a second threaded portion of the bumper. When the apparatus is in use, the hose portion is pressed against the pair of reverse-angled serrations and the plurality of secondary serrations using the band clamp. In order to do so, the band clamp is positioned adjacent the bumper such that a body of the band clamp perimetrically surrounds the pair of reverse-angled serrations and the plurality of secondary serrations.

Abstract: A tracheal tube assembly includes a connector body, a cannula extending from the connector body, and an insert that provides rigidity to the connector body and retains the cannula in the connector body. The cannula has an upper end that fits between conforming tapered sections of the connector body inner surface and the insert. The insert may include features to mitigate stress on and around any secondary lumens in the cannula wall. Because the wall is thinner at the site of a secondary lumen, the connector body insert may include a recess into which the cannula wall may expand. The recess may be aligned with the secondary lumen.

Abstract: A hose nipple (4) for a hose arrangement (1) is provided, having retaining ribs (6) on the outer side. According to the invention, the retaining ribs (6) vary in their form, size and arrangement on the nipple base body (5) between the hose side (12) and the outlet side (11) of the hose nipple (4) such that a uniform and parallel input of force into the pressure hose (2) is achieved by the retaining ribs (6), which causes the force- and/or form-fitting connection between the hose nipple (4) and the pressure hose (2) fitted thereon.

Abstract: An oil feeding device includes a tube body formed of metal and having a tube connecting part, and a connection pipe formed of resin and having a pipe connecting end. A press-fitting member and a seal member are clamped between the tube connecting part and the pipe connecting end. The press-fitting member includes a press-fitting body having a cylindrical outer peripheral face which is fitted to an outer periphery of the tube connecting part, and claws which are formed at one end of the press-fitting body. The pipe connecting end is provided with a reduced diameter part which is formed by annularly reducing a diameter of a part of the pipe connecting end. The reduced diameter part is so formed as to retain the pipe connecting end, in engagement with the claws, by being formed by plastic deformation in advance before the pipe connecting end is connected to the tube connecting part or after it has been connected.

Abstract: A hose coupling assembly for attachment to a hose having an inner surface and an outer surface. The hose coupling assembly includes a first member (e.g., a nipple) and second member (e.g., a socket). The nipple includes a tapered outer surface, an outwardly facing groove extending inwardly from the tapered outer surface, and a set of external threads disposed rearward of the tapered outer surface. An annular seal is positioned within the groove. The socket includes a nipple receiving portion and a hose receiving portion secured to the outer surface of the hose, where the nipple receiving portion has a set of internal threads configured to mesh with and threadingly engage the external threads on the nipple. Upon insertion of the nipple into the nipple receiving portion of the socket and the subsequent threading of the external threads of the nipple into the internal threads in the socket, the annular seal on the nipple sealingly engages the inner surface of the hose.

Abstract: A quick connector includes: a connector body having a retainer holding portion, a tube connecting portion to be press fitted into a tube, and a housing between the retainer holding portion and the tube connecting portion, the tube connecting portion being formed with a plurality of annular projections being axially spaced apart from each other; and a retainer which is held in an axially fixed state by the retainer holding portion. A portion of an outer surface of the tube connecting portion extending from the annular projection, which is closest to the housing, toward the housing is formed into a tapered surface whose diameter is gradually enlarged toward the housing, and a diameter of an annular projection side of the tapered surface is set to be larger than a diameter of the outer surface of the tube connecting portion between the annular projections.

Abstract: An improved fitting having an improved flexible tubing tip to connect to flexible tubing, e.g., FUNNY PIPE brand polyethylene pipe, used for sprinkling systems and other fluid delivery systems. According to one aspect of the present invention, one or more annular barbs are positioned at or toward the back of the portion of the fitting inserted into the flexible tubing, with a threaded or spiral or helix portion being positioned at the front of the portion of the fitting inserted into the flexible tubing. According to another aspect of the present invention, the threaded or spiral or helix portion of the fitting is slightly tapered to facilitate insertion into the flexible tubing. According to yet another aspect of the present invention, a double helix spiral thread is used.

Abstract: A collar for a connection between a resilient tube and a rigid barbed connector. The collar comprises a generally cylindrical sleeve member having interior annular ridges. When the collar is installed on the tube surrounding the barbed connector, the ridges press into the tube and prevent expansion of the tube to prevent leakage between the tube and the connector.

Abstract: The invention relates generally to a solderless metallic-encased, polymeric-lined connector system.
