A fluid line component with a fluid duct, a sealing surface which surrounds the outlet of the fluid duct on an outer side of the fluid line component, and an axial seal which bears against the sealing surface and can be brought to bear against an opposite surface of a mating piece in order to connect the fluid duct leaktightly to a duct in the mating piece. The axial seal has a support and a sealing element which is assembled on the support, wherein the support can be displaced relative to the sealing surface. The invention also relates to an assembly with such a fluid line component, wherein the fluid line component is a hydraulic pump and the mating piece is a receptacle in a housing of a fluid storage tank.

An industrial process field device includes a pressure sensor, and a housing containing the pressure sensor. The housing includes a base having a base interface and a first base process opening. A flange is attached to the base and includes a flange interface having a first flange process opening. A first gasket process opening of a gasket is aligned with the first base process opening and the first flange process opening. A first surface of the gasket engages the base interface, and a second surface of the gasket engages the flange interface. A dielectric insulation system includes at least one dielectric layer that insulates the housing from electrical currents conducted through the flange. Each dielectric layer includes a layer of ceramic material, an anodized layer, or a plastic overmold, which improve a maximum working pressure of the field device.

A sealing assembly for flanges is described. The sealing assembly includes a wedge, a first sealing element, a second sealing element, and a fastener. The wedge has a first surface, a second surface, and a third surface. The first surface defines a pressure void with a first flange and a second flange. The first sealing element engages the second surface of the wedge and the first flange. The second sealing element engages the third surface of the wedge and the second flange. The fastener couples the first sealing element, the first flange, the second flange, and the second sealing element together. The wedge slides toward the sealing elements responsive to a pressure increase in the pressure void. The sealing elements force the flanges toward each other responsive to the wedge sliding toward the first sealing element and the second sealing element.

Clamping system for connecting two tubes having protruding clamping surfaces. The system comprises a collar having a strip able to cooperate with the clamping surfaces. The strip has a first and a second flank between which an inner recess able to receive the clamping surfaces is delimited. The system comprises at least one retaining clip comprising a cross-member which extends across the inner recess, a first and a second wing which extend radially outwardly relative to the cross-member by covering the flanks and a first and a second retaining configuration each comprising at least one retaining lug. The cross-member is able to be deformed to penetrate into the inner recess.

A joint assembly for joining two pipes together comprises first and second liners and first and second pipe flanges. Each liner includes a sleeve and a liner flange with the liner flange coupled to one end of the sleeve. The first liner may be positioned within a first pipe and the second liner may be positioned within a second pipe. Each pipe flange is of generally annular disc shape with an inner surface, an opposing outer surface, an inner edge, and a radially-spaced outer edge. Each pipe flange includes an annular outer recess formed on the outer surface adjacent to the inner edge. The first pipe flange may be coupled to one end of the first pipe and the second pipe flange may be coupled to one end of the second pipe. Each liner flange may be positioned within the outer recess of a successive one of the pipe flanges.

A structure allowing a gasket to be mounted on a fluid device is provided. The gasket includes an annular attaching portion that has a first slope at an axial end. The fluid device includes an annular attached portion with a second slope that contacts the first slope. The first slope at least partially includes two or more pressing areas, which are partitioned by annular steps. The second slope at least partially includes two or more pressed areas, which are partitioned by annular steps to fit the steps between the pressing areas.

A fluid-device connecting structure includes a first fluid device having a first connection part, a second fluid device having a second connection part, an annular seal member to connect the first and second connection parts, and a coupling member to keep the first and second connection parts in a connected state. The coupling member includes a first coupling segment and a second coupling segment, each including at one end a first hinge part or a second hinge part. The first and second connection parts each have a cylindrical outer shape. The first coupling segment has a U-like shape having an opening and surrounds the first and second connection parts over a range more than 180 degrees of an entire circumference of each of the first and second connection parts.

A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

A coupling for interconnecting pipes, hoses, or the like, includes a male coupling component configured to form a coupling with one or more female coupling components. The male coupling component comprises an annular, hollow body portion having a nose at one end defining an annular sealing surface and a locking ring mounted on an exterior of the body portion adjacent the nose. The locking ring has at least one slotted-opening extending longitudinally therethrough and is rotatable and translatable relative to and about the hollow body portion. A female coupling components is able to be locked to the male coupling component via engagement with the locking ring of the male coupling component.

A first projection is formed on the outer periphery of a bulb part, a second projection is formed on the socket rear end of the bulb part, a tapered part is formed with a decreasing diameter from the inner periphery of a heel part to the inner periphery of the second projection, and a third projection is formed on the tapered part. A first dimension B from the first projection to the third projection in an inclination direction opposite to an inclination direction G of the tapered part is smaller than a second dimension C from the first projection to the second projection in a radial direction A.
