Aspects of the present disclosure relate to modular end apparatus, such as modular end fitting apparatus, and methods for flexible hoses, and associated components thereof. In one implementation, a flexible hose apparatus includes a flexible hose and a hose body coupled to the flexible hose, the hose body including a threaded outer surface. The flexible hose apparatus includes a cap including an inner shoulder protruding inwardly relative to a first inner surface of the cap. The flexible hose apparatus also includes a removable end fitting disposed in engagement with the cap. The removable end fitting includes an end body that is monolithic. The end body includes a first end, a second end opposite of the first end, and a first outer shoulder adjacent the first end and disposed between the hose body and the inner shoulder of the cap.

A connector seal pack spacer and assembly are employed for use in a fluid line quick connector in an automotive application, for instance. The spacer is located beside an o-ring in installation in the fluid line quick connector. The spacer is designed and constructed with an angled surface that, upon insertion of a spigot in the fluid line quick connector, works to maintain an intended position of the o-ring in the fluid line quick connector. Unwanted mispositioning and dislodging of the o-ring is hence minimized and, in some cases, altogether precluded.

A safety valve arrangement and method, having an upstream block valve, a downstream block valve, and a pressure monitored galley between the upstream valve and the downstream valve.

Each of a pair of couplers includes: a vacuum double-pipe structure main part; a valve seat forming an opening through which a fluid flows; and a valve body in the main part. The valve body is configured such that, when separating the couplers, in each coupler, the body is brought into contact with the seat by a spring to close the opening, and when coupling the couplers, the body of each coupler is pressed by the body of the other coupler to move away from the seat and open the opening. The valve body includes: a holding member holding a sealing material sealing between the body and the seat when the body is in contact with the seat; a resin block covering a distal end surface of the holding member; and a metal operating member accommodating the block and protruding from the holding member to pass through the opening.

An expansion joint fitting for conveying liquid includes a radially inner bellows defining a liquid-conveying passage for conveying liquid between the first and second longitudinal ends of the expansion joint fitting. A radially outer bellows is disposed radially outward from and extending around the radially inner bellows. An annular plenum is defined between the radially inner bellows and the radially outer bellows.

The invention relates to a connection device comprising —a line portion (10) having, at its end, a radially outwardly projecting abutment flange (14) for butting against a corresponding abutment flange of a further line portion which is to be coupled to the line portion (10), and—a ring-segment chain (42, 22, 38) comprising a plurality of ring segments (22, 38) connected to one another in a pivotable manner in a common ring plane, wherein the ring-segment ends which formed the chain ends can be latched to one another to give a ring-form connection clamp (42). The invention is distinguished in that the line portion is designed in the form of a tubular connection stub (10) with first thread means (16) spaced apart axially from the abutment surface (141) of its abutment flange (14), and in that each ring segment (22, 38) has a radially inwardly projecting clamping flange (24) and second thread means (26), which are spaced apart axially from said clamping flange and correspond with the first thread means (16).

To provide a pipe joint that can immediately shut off a hydrogen gas flow path at an initial stage when a plug (nozzle side member) comes out of a socket (filling apparatus side member) to prevent release of outgas. A pipe joint (100) of the present invention includes: a cylindrical nozzle side member (10) with a shutoff valve (5), in the cylindrical nozzle side member (10) being formed a passage (1A); and a cylindrical filling apparatus side member (20) with a shutoff valve (24), in the cylindrical filling apparatus side member (20) being formed a passage (21A), wherein when the nozzle side member (10) and the filling apparatus side member (20) are connected with each other, central axes of the passages (1A, 21A) of the nozzle side member (10) and the filling apparatus side member (20) do not form a same straight line, and the central axes of the passages (1A, 21A) are offset without intersecting, and the shutoff valves (5, 24) of the both members (10, 20) open to communicate the passages (1A, 21A) of the both members (10, 20) with each other, and when the nozzle side member (10) is separated from the filling apparatus side member (20), the shutoff valves (5, 24) of the both members (10, 20) close.

This multi-couplings plate (P1) includes a locking device comprising a frame (14) fixed on the plate (P1), locking members and a drive mechanism, comprising a rotary element (18) rotatable in the frame (14), a sliding element translatable relative to the frame (14) and which cooperates with the locking members. The locking device also comprises several ratchet notches (301-309) secured to an element (18) of the drive mechanism (16) and juxtaposed in the movement direction relative to the frame (14) of the element (18) of the drive mechanism, the ratchet notches (301-309) comprising a final notch (309) and at least one intermediate notch (303-308), and a pawl movable in a housing (326) of the frame (14) and pushed back by a spring (28) toward one of the ratchet notches (301-309). When the pawl cooperates with the intermediate notch (303-308), the pawl limits the movement of the sliding element toward its forward position to a position midway between the forward position and the withdrawn position, and in the coupled configuration, the pawl cooperates with the final notch (309) and keeps the sliding element in the withdrawn position.

An apparatus for shrouding the coated field joint area of connected line pipe segments, the shroud having first and second housing halves which have end walls which cooperate to form registering openings matching the diameter of the pipe to be shrouded, the housing halves forming a chamber. The housing can be of a clamshell design, being hinged on one side and having hasps, latches or the like on the other side to keep the shroud positioned once it is placed around the coated field joint area of a pipeline. An environment monitor is disposed in the chamber to measure conditions such as relative humidity and temperature.

A junction part having a differential pressure valve (100) for an undersea fluid transport pipe, the valve having a valve body (102) with an internal chamber (106) opening out at one end into the pipe and at another end to the outside, a piston (110) arranged to subdivide the internal chamber into an admission chamber (106a) and a discharge chamber (106b), the piston being movable between an open position where admission chamber and the discharge chamber communicate with each other, and a closed position where the admission chamber and the discharge chamber are scaled from each other, a rating screw (112) screwed into the valve body and including a bore (114) within which there slides a rod (116) of the piston (110), and at least one hole (118) opening out into the discharge chamber and open to the outside, and a spring (120) rated so as to hold the piston in the closed position below a predetermined threshold pressure inside the admission chamber.
