A water heating device equipped with a housing, a fan and a chamber arranged in the interior of the housing, and screws. The housing has first and second side plates which oppose one another in a first direction and extend from the ends of a back plate along a second direction intersecting the first direction. An opening part is provided in the housing on the side opposite the back plate in the second direction. The fan has a discharge opening, a first flow passage extending along the first direction, and a first flange. The chamber has an intake opening, a second flow passage extending along the first direction, and a second flange. The first and the second flanges are secured by screws. In a planar view, the center axis of the screws is slanted such that a head portion is closer to the opening part than the tip-end portion.

Apparatus and methods for terminating an end of flexible pipe body are disclosed, the apparatus comprising an elongate end fitting body, associated with a central longitudinal axis, comprising a connector flange region securable in a back-to-back relationship to a further end fitting body and disposed at a first end of the elongate end fitting body, an open mouth at a remaining end of the end fitting body, a central flange region disposed between the first end and the remaining end and a neck region between the central flange and the connector flange, wherein the neck region comprises a radially inner end fitting neck region portion and a radially outer end fitting neck region portion that is spaced apart from and is radially outside the radially inner end fitting neck region portion to provide an enclosed chamber region therebetween.

A vibration damping connector system to connect between a vacuum chamber and a vacuum pump such that the vacuum pump is supported by the vibration damping connector system includes a first cylindrical member and a second cylindrical member that provide a flow passage through which gas can flow from the vacuum chamber to the vacuum pump. At least one sealing member is disposed intermediate the first and second cylindrical members to provide a gas seal and a securing system securely connect the first and second cylindrical members. At least one resilient member disposed intermediate the securing system and a cylindrical member so that when the at least one sealing member is compressed by a pressure reduction caused in use by operation of the vacuum pump, the at least one resilient member can expand to enable the securing system to maintain a secure connection.

A polymer-lined fluid transmission line includes various structures, including a first polymer-lined pipe, a second polymer-lined pipe, and one or more sleeve retainers installed at a pipe junction between the polymer-lined pipes. Among other things, the sleeve retainers may include one or more protuberances to frictionally engage the polymer-lined pipes or a one or more portions that protrude into a space between the polymer-lined pipes to help retain and protect polymer sleeves.

A composite pipe termination is provided. The composite pipe includes a composite pipe wall thickness and a cut end. An annular part of composite material is attached around the outside of the composite pipe at the cut end. The annular part has a radial thickness which tapers towards the composite pipe in the direction along the composite pipe away from the cut end to provide an exterior surface having a tapered portion. A pinning structure includes one or more pins which extend through the annular part and partially through the composite pipe wall thickness to further attach the annular part to the composite pipe.

A gland assembly includes a gland defining an annular ring, the annular ring defining a first gland end and a second gland end disposed opposite from the first gland end; and a gasket, the gasket defining a first gasket end and a second gasket end, the first gasket end disposed opposite from the second gasket end, a gasket bore extending through the gasket from the first gasket end to the second gasket end, a gland collar defined at the first gasket end, the gasket bore receiving the second gland end of the annular ring.

A vibration suppressing piping member suppresses vibration caused by a pulsating discharged gaseous fluid. The piping member includes a tubular portion and flange portions at both ends of the tubular portion. A bent portion is formed between the two flange portions. The two flange portions are directly connected to each other.
