Provided is a pipe holding connection structure configured so that the width of the entire structure is reduced and so that the number of parts and the number of assembly work processes are reduced. This pipe holding connection structure is provided with: a housing affixed so as to air-tightly close the opening of a vacuum container; a first pipe having a portion near an end portion thereof extending through both the opening and the housing; and a second pipe having a female thread part engaging with a male thread part located at the end portion. The pipe has a locking part. Fluid is caused to flow through both the pipes. Pieces of packing are provided between the pipe and the housing and between the pipe and an end portion of the pipe, respectively. This pipe holding connection structure can be used for a high-frequency antenna device.

A penetration fitting assembly includes a pipe gasket having an annular portion defining a central opening and first and second stem portions extending in opposite directions from the annular portion, an inner ring assembly configured to surround the pipe gasket and including first and second inner ring halves, a ring gasket assembly configured to surround the inner ring assembly and including first and second ring gasket halves, a wall gasket, an outer ring assembly configured to surround the ring gasket assembly and including first and second outer ring halves, and a clamp configured to surround the outer ring assembly. When the penetration fitting assembly is installed, the outer ring assembly compresses the wall gasket against the wall of the sump, the clamp compresses the ring gasket assembly between the inner ring assembly and the outer ring assembly, and the clamp compresses the pipe gasket against the pipe or conduit.

A system has a surface intended to separate two chambers within the system. The surface has an aperture for allowing passage of at least one communication conduit. A shroud is positioned on the surface at the aperture, and has at least two portions defining a central opening to allow the communication conduit to pass through the aperture and shroud. The two portions of shroud have mating clamp ears in contact with each other. Securement members tighten the clamp ears against each other to provide a seal at an end of the shroud remote from the surface.

An environmental monitoring pipeline closure and a wireless positioning and warning system thereof are disclosed. The environmental monitoring pipeline closure is composed of an upper platen, an expansion body, a lower platen, a plurality of bolts, and a plurality of compression rings, on which a plurality of clamping holes are provided for holding and fixing a cable line. A gas sensing device is provided inside the pipeline closure to detect gas concentrations within the space inside a manhole channel when being installed in the underground manhole channel. The measured data is transferred to a monitoring device through wireless transmissions to keep monitoring gas concentrations within the manhole channel. This prevents injuries and deaths of people working inside the manhole channel due to a lack of oxygen or inhalation of harmful gases.

A flanged pipe is mounted to a perforated fixed plate by limiting movement of the pipe in three mutually perpendicular axes, and rotationally around the plate axis. The mount consists of a plate and a flanged pipe. The pipe exterior is decorated with ribs parallel to the pipe axis. Each rib bears a microclip positioned to allow the plate to rest between the pipe rib microclips and the underside of the pipe flange. The perimeter of the plate perforation bears cutaways. Inserting the pipe through the perforation of the fixed plate engages the ribs with the cutaways to limit rotational movement. Movement in the plane perpendicular to the plate axis is limited by complementary diameters of the plate perforation and the pipe. Engagement of the flange on the plate limits movement of the flanged pipe through the plate perforation. Pipe retraction is limited by microclips.

A seal, lead-through or transit for cables, wires or pipes which seal, lead-through or transit has one or more compressible parts surrounding the cable, etc. and a position of an opening receiving the cable, etc. is adjustable. In one example, the opening may be placed off-center on a partition line between two module parts. In other example, an inner compressible body may be placed inside an outer compressible body or between two module parts. The inner compressible body has an opening receiving the cable, etc. which opening is placed off-center. By rotating the inner compressible body the position of the opening receiving a cable, etc. is adjusted.

A wedge clip (13) to be used to control the compression of a compression unit. The compression unit is part of a transition for cable or pipes., The transition further comprises a frame (1) and modules (3) placed inside the frame (1), whereby also the compression unit is placed inside the frame (1). The compression force is increased by turning two screws (5) of the compression unit outwardly and a distance between heads of the two screws (5). The compression unit as such is an indication of the applied compression force. The wedge clip (13) is adapted for use on said compression unit. The wedge clip (13) is formed of an elongated plate (14) bent over itself.
