A wastewater tank arrangement for an aircraft, including a wastewater tank and a drain pipe having a first end and an opposite second end, the drain pipe fastened with its first end to the wastewater tank and having a second end for connection to a service panel in the aircraft structure. Providing a wastewater tank arrangement can effectively compensate tolerances between the wastewater tank and the service panel, and can effectively compensate installation and manufacturing tolerances during the course of the initial installation, in that the wastewater tank arrangement has a tolerance compensation device configured to connect the second end of the drain pipe to the service panel and compensate tolerances between the second end of the drain pipe and the service panel.

Methods and systems are provided for a coupling device. In one example, the coupling device may be formed of a composite material and positioned between an exhaust system and a vehicle chassis. The composite material may include aluminum particles dispersed in an elastomer matrix to reduce an overall thermal absorptivity of the composite material.

A line element includes an inner element, an outer element surrounding the inner element, and a damping element arranged between the inner element and the outer element. The damping element can be made, for example, of knitted wire fabric or a stripwound hose. The damping element can be made in particular of a more easily wearing material than the outer element and/or the inner element, for example of copper.

A wand includes a hinge configured to pivotally connect first and second wand segments in an extended configuration and a storage configuration. A first locking mechanism locks the wand in extended configuration. A second locking mechanism includes a rod, a sliding lever, a plunger, and a plunger cavity. The plunger is configured to be received in the plunger cavity to lock the wand in the storage configuration. When in the extended configuration, depressing a single actuator pivots the locking arm, causes the hook/pawl to be removed from the locking cavity, and unlocks the wand. When in the storage configuration, depressing the single actuator causes the rod to move in a first direction, causes the sliding rod to move a second direction, and urges the plunger out of the plunger cavity.

A system may a first frac tree having a first inlet, a manifold having a first fluid outlet, and a first flexible pipe. The first flexible pipe may include a first end of the first flexible pipe coupled to the first fluid outlet; a second end of the first flexible pipe is coupled to the first inlet; and a first outer shell rotationally mounted on the manifold, the first outer shell extends from the manifold a length between the first end and the second end. The first outer shell may extend from the manifold a length between the first end and the second end. Additionally, the first outer shell is curved to have a radius to arch the first flexible pipe from the manifold to the frac tree.

A swivel joint including a flange assembly and an inner joint that is configured to rotate with respect to the flange assembly. The flange assembly may include a first flange and a second flange that is secured to the first flange. The inner joint may have a main body and a radial extension extending outward from the main body with the radial extension positioned between the first flange and the second flange. A first thrust bearing may be positioned between the radial extension and the first flange, and a second thrust bearing may be positioned between the radial extension and the second flange. A first seal and a second seal may each be positioned between the flange assembly and the inner joint. A leak indicator may be positioned between the first seal and the second seal. The first and second thrust bearings may be caged bearings.

An expansion pipe joint that absorbs displacement occurring at a connection portion between an upstream pipe and a downstream pipe includes an outer tube having a downstream end coupled to the downstream pipe, an inner tube that is inserted into the outer tube and has an upstream end coupled to the upstream pipe, and a closing member having elasticity that is provided between an upstream end of the outer tube and the upstream end of the inner tube so as to close a gap between them. Then, a difference between a position in an axial direction of the upstream end of the outer tube and a position in the axial direction of the upstream end of the inner tube is within a predetermined range so that a bus line of the closing member is inclined from the axial direction.

A system includes a conduit and a gasket assembly. The conduit includes a body and has a bell defining an opening disposed at one end of the conduit. The bell includes a ridge defining a circumferential internal groove, a sloping portion defining an internal recessed area and disposed adjacent to the ridge, and an abutment end inwardly extending from the sloping portion in a direction that is perpendicular to a central axis defined by the bell. The gasket assembly is disposed within the internal groove. The gasket assembly includes a plurality of gripping inserts each comprising a hollow body and an elastomeric gasket having a circular shape and being disposed within the hollow bodies defines by the plurality of gripping inserts.
