A delivery assembly for a crop input delivery system. The delivery system includes a boom adapted to be supported at a proximal end from a mobile vehicle, the mobile vehicle holding a supply of the crop input, the boom supporting a conduit having a proximal end in fluid communication with the supply of crop input. The delivery system further includes a first coupler and a second coupler. The first coupler is supported on a distal end of the boom and is coupled to the conduit. The second coupler is in fluid communication with a storage tank disposed on the implement, the second coupler configured to fluidly couple with the first coupler. A clamping assembly releasably couples the first and second couplers in fluid engagement.

A chemical delivery system connects to a chemical tank and includes a union connected to the tank outlet and providing an antirotation feature, in addition to threads, to prevent rotation of the assembly in response to asymmetric loads. A measuring tube alternately receives liquid from the tank and is isolated from the tank. While isolated from the tank, liquid is withdrawn from the tube by a pump under conditions allowing the pump to be calibrated. The assembly is cantilevered from the tank outlet and is of reduced length and weight producing a device which is not prone to overstress the tank outlet.

A non-metallic fluid coupling is disclosed with electrical current transferring elements incorporated therein. The coupling is formed of two C-shaped halves of non-metal, non-conducting material, where each halve includes integral hinges and latches, or hinges and latches made of a common material with the C-shaped halves. A non-metallic, substantially rigid sealing sleeve can be incorporated into the coupling to seal the coupling while maintaining the strength of the coupling.

A connection assembly and a method comprises first and second connector portions having a preload mechanism comprising a plurality of bores and threaded fixings circumferentially spaced around the axis, wherein the preload mechanism is arranged to apply an axial load between shoulders on the first and second connector portions when torque is applied to the threaded fixings. An annular sealing member is compressed between the first and second portions, and the axial load applied between the first and second shoulders by the preload mechanism exceeds a peak hydrodynamic load urging the first and second connector portions in a direction along the axis. The axial force applied by the preload mechanism advantageously reduces the fatigue damage experienced by the connection, for example, by cyclic pressure changes within the connector portions typically caused by pumps operating at high pressures.

A pipe joint for coupling to at least one pipe is disclosed in the present invention. The pipe joint includes a main body and at least one positioning socket. The main body has a runner and at least one opening communicated with the runner. The runner has an insertion area adjacent to the opening. The positioning socket has a head, an inserting portion, a pipe channel, a radial threaded hole and a bolt. The inserting portion is inserted into the runner via the opening. The pipe channel runs through the head and the inserting portion in an axial direction of the positioning socket. The threaded hole is formed on the head and communicated with the pipe channel. The bolt is adapted to engage with the threaded hole for abutting against the outer surface of the pipe.

The invention concerns a pipe joint formed between a pin section (10) and a box section (20); the pin and box sections each having a tubular pipe section, engaging at respective first ends in end-to-end arrangement and having a seal element partially therebetween, the box section including a collar extending from the first end, the collar being generally cylindrical, axially aligned with the tubular box pipe section and having an inner diameter of the same size as the outer diameter of the pin section, enabling the collar to be placed about the pin section, the pin and the box sections being secured together by means of a plurality of securing means housed in the collar and actuable to exert radial pressure to urge the pin and box into sealing arrangement, the collar (22) of the box section (20) including a test port, comprising a housing atrium, defined by an atrium wall, housing a test plug (60); the housing atrium (61) and the seal element (53) being fluidly linked by a box conduit; the plug comprising a plug body and a plug seal housed between the plug body and the housing atrium wall to seal the housing atrium from atmosphere and having therethrough a plug conduit connectable at a first end to a pressure test apparatus and fluidly linkable at a second end to the box conduit; the plug being moveable between a first position forming a fluid link between the plug conduit and the box conduit, and a second position closing the fluid link.

The present invention relates to a boltless bonnet assembly for use in a blowout preventer (BOP). In some embodiments, the boltless bonnet assembly includes a bonnet having a forward end facing a ram body of the BOP stack, and a bonnet latch disposed within the bonnet, the bonnet latch attached to the forward end of the bonnet. The boltless bonnet assembly further includes a bonnet positioning mechanism in communication with the bonnet latch to move the bonnet latch into and out of engagement with the ram body.

A connection nozzle assembly includes an inner fluid product tube, a tube sleeve secured about the fluid product tube, an outer nozzle sleeve, and a locking mechanism disposed between the fluid product tube and the nozzle sleeve. The nozzle sleeve includes a body portion and a rear portion, each being moveable between a plurality of locking positions. The body portion has at least one J-groove bracket disposed therein and the rear portion has a guide element extending into the bracket. The locking mechanism includes at least one clamping member moveable between a plurality of clamping positions and at least one drop pin moveable between a raised position and a lowered position. The nozzle sleeve is moved between the plurality of locking positions, thereby engaging the locking mechanism to secure the connection nozzle assembly to a receptacle coupling. The connection nozzle assembly can be uncoupled by reversing the nozzle sleeve.
