A fracturing fluid delivery system is provided. In one embodiment, the system includes a fracturing manifold and a fracturing tree. A fluid conduit is coupled between the fracturing manifold and the fracturing tree to enable receipt of fracturing fluid by the fracturing tree from the fracturing manifold through the fluid conduit. Further, the fluid conduit is an adjustable fluid conduit that provides a line-of-sight fluid connection from the fracturing manifold to the fracturing tree. Additional systems, devices, and methods are also disclosed.

The connector includes a sleeve (4) which is screwed on to a thread (18) provided on an upper axial end of the lower riser section (1). The sleeve (4) encloses a lower end of an upper riser section (2) and is retained thereto. Once the sleeve (4) is secured to the lower riser section, this loosely secures the upper riser section (2) to the lower riser section (1). A tensioning tool then stretches the sleeve (4) upwardly and a retaining collar (5) is then maneuvered in order to retain the sleeve (5) in this tensioned state after the release of the tensioning tool. This creates a preloaded connection between the upper riser section (2) and the lower riser section (1).

An air intake duct, of a saddle-riding type vehicle, in which a flow velocity of an intake air is less likely to be reduced to enable prevention of reduction of an efficiency of a supercharger, is provided. The air intake duct of a motorcycle serves to supply incoming wind as the intake air to the supercharger for a combustion engine. The air intake duct has a passage area that is gradually reduced from an air intake port at a front portion toward a downstream portion connected to the supercharger at a rear portion.

A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe.

A stainless steel 316 hose with buoyancy counterweights is demonstrated that is heavy enough to sink even when full of air that would normally have sunk without having to use concrete mats or other anchoring means. The buoyancy counterweights can be steel pipe segments that the hose is run through and welded to or spurious flanges that are welded to the hose at discrete increments.

An apparatus for measuring external corrosion in pipes is disclosed.

An apparatus includes a foreline for conveying a waste stream which is drawn from a process chamber to a pumping mechanism. The foreline comprises an isolation valve for selectively isolating the pumping mechanism from the process chamber and a bypass positioned around the isolation valve. The apparatus further comprises a controller for actuating the isolation valve. The controller is configured to cause the isolation valve to be closed when the waste stream is initially drawn from the process chamber, during which time the waste stream is conveyed to the pumping mechanism via the bypass. The bypass includes means for inhibiting propagation of a flame front therethrough. The controller is configured to cause the isolation valve to be opened once a pressure within a region upstream of the isolation valve has been reduced below a value at which propagation of a flame front within the waste stream can be sustained.

Systems, methods, and devices for preparation of purified water and medicaments for various uses including blood treatment are described. Methods, devices, and systems for creating multiple-treatment batches are described. For example, a medicament fluid circuit can include a container with an interior chamber. The container can have a fluid filling port and a fluid extraction port. Both ports can be connected to the interior chamber. The filling port can have two sterilizing filters, each of which has a membrane. The sterilizing filters can be connected in series the membranes are separated by a distance of at least 0.5 cm. A first of the sterilizing filters can have a sealed inlet. The fluid extraction port can be sealed.

A tubular threaded connection includes a threaded sub-assembly having a first tubular member, a first torque member threadingly received on the first tubular member, and a second torque member threadingly received on the first tubular member. In forming the threaded sub-assembly, the first torque member is torqued relative to the second torque member. Furthermore, the sub-assembly is configured to receive a second tubular member for torqueing against the sub-assembly.
