Abstract:
The tube main body (12) of a curved tube (10) has a flow path following the axis line (12A), and has a curved section (14) in one portion of the direction along the axis line (12A). Further, in the inner periphery (14A) on the inside of the curve direction of the curved section (14) in the tube main body (12), a depression (16) is formed as an expanded cross-section portion along the direction of the axis line (12A). Further, in the inner die of the die for forming the curved tube, a hinge core forming the depression is inserted in a groove of the main core, and by the main core moving towards a retracted position, the tip of the hinge core, which has a shape that engages the inner periphery (14A) on the inside of the curve direction of the curved section (14), swings towards the formation position of the main core.
Abstract:
A connector with a biocompatible fluid passageway and method for manufacturing thereof is described. The biocompatible connector may be used in an analytical instrument (AI) system as a union, an adapter, a tee, a cross, a manifold, a valve, a column filter retainer, or for other fittings or components. The connector has a reinforcement insert and a biocompatible molding covering portions of the reinforcement insert. The reinforcement insert has a first portion, a second portion, and a middle portion between the first portion and the second portion. The first and second portions have threaded sections and each have a plurality of non-threaded sections. For a given portion, the junction of the non-threaded sections forms a lip by which to prevent the molded material from flowing into the threaded sections. In certain embodiments, an interior web is used in the reinforcement insert to provide additional structural support.
Abstract:
Devices and methods for coupling fluid conveying piping (12) in an arrangement to provide a one or more branch connections. A mechanical fitting includes a lower housing (110a) and an upper housing (110b) coupled to one another to define an interior space (112) for housing a tubular pipe segment (12). At least one insert (200) for insertion in one of the upper or lower housing includes a tubular body (200b) that defines a fluid flow passageway (202) and a base (200a) that engages an opening (14) in the pipe segment (12). The base and housings are configured to engage one another to prevent rotation of the insert (200) with respect to the housing (110).
Abstract:
This invention relates to a tube fitment that is used with a valve fitment assembly used to dispense fluids or flowable materials from a container. The tube fitment is utilized in conjunction with the valve fitment assembly to allow the fitment assembly to be used with a spout and valve assembly attached to a container holding fluid. This invention also relates to a process for dispensing fluid using the adapter described herein.
Abstract:
Apparatus for use in sampling multiphase fluid in a fluid transport pipeline, the apparatus comprising: a process fluid conduit (10) comprising a blind leg (16) connected to an upstream section (12) and a downstream section (14); and wherein a fluid sampling port (18) is provided in the blind leg.
Abstract:
The present disclosure generally refers to a double-walled fuel supply line element (5) configured to be used in a fuel supply system (100) of e.g. middle to large-sized internal combustion engines and a method for manufacturing such a fuel supply-line element (5). The double-walled fuel supply line element (5) may comprise an inner line element (10), an outer line element (40), and a connecting structure (70) configured to fixedly arrange the outer line element (40) around the inner line element (10) such that a tubular hollow space (50) is provided between the inner line element (10) and the outer line element (40). The inner line element (10), the outer line element (40), and the connecting structure (70) may be integrally casted.
Abstract:
A rotationally molded large-diameter pipe fitting, the wall structure of which is characterized as having a generally smooth interior surface and an exterior surface that is defined by a plurality of axially-spaced circumferentially extending ribs which are monolithically formed and homogeneous with the smooth interior surface of the fitting. The fitting is seamless and modularly designed with integral coupling elements at each terminal end, and with a ribbed wall structure profile capable of withstanding the loads typically found in buried applications with watertight performance requirements, where such ribbed wall structure meets the following dimensions and dimensional ratios: Rib Sidewall Angle (95 - 105 degrees); Bottom / Top Rib Thickness Ratio (1.80 - 2.80); Pitch / Rib Height Ratio (1.50 - 1.95); Rib Height / Fitting Diameter Ratio (0.04- 0..09); and Avg. Rib Thickness / Rib Height Ratio (0.28 - 0.40).
Abstract:
A piping assembly for directing fluid and mitigating acoustic and vortex coupled resonance is provided that includes a main pipe delivering fluid in a first direction; a standpipe coupled to the main pipe at an intersection; and a scoop positioned at the intersection directing the fluid towards the standpipe. A scooping insert and a method for disrupting vortex shedding in a piping assembly are also provided.
Abstract:
Die vorliegende Erfindung betrifft ein Verbindungselement (1) für Strömungsmedien, bestehend aus einem insbesondere im Wesentlichen einstückigen Verbinderteil (2) mit mindestens zwei Anschlussabschnitten (4) jeweils zum Anschluss an eine Medienleitung oder ein Aggregat sowie mit einem zwischen den Anschlussabschnitten (4) angeordneten Übergangsabschnitt (8). Die Anschlussabschnitte (4) weisen jeweils einen inneren Anschlusskanal (6) auf, und die Anschlusskanäle (6) sind bezüglich ihrer Längsachsen (10) in einem bestimmten Verbinderwinkel (α) zwischen 0° und 180° zueinander ausgerichtet und über den Übergangsabschnitt (8) strömungsmäßig miteinander verbunden. Die Anschlussabschnitte (4) sind bezüglich ihrer Längsachsen (10) zumindest im Bereich des Übergangsabschnittes (8) derart um einen Versatz (X) gegeneinander versetzt angeordnet, dass innerhalb des Übergangsabschnittes (8) ein Verbindungsraum (12) mit einem relativ zu den Querschnitten der angrenzenden Anschlusskanäle (6) vergrößerten Strömungsquerschnitt gebildet ist.
