A guided wave radar level gauge adapted for mounting on a nozzle of a tank, including an attachment collar with an opening configured to be aligned with the nozzle and to be secured by means of an annular clamping device, and a transmission line probe attached to an exterior end of a probe connector. The GWR level gauge further comprises an annular sealing gasket fitted in the collar opening, the annular sealing gasket having a central opening through which the central probe connector extends, and a distancing sleeve arranged around the exterior end of the probe connector and having a radially protruding collar portion, wherein processing circuitry is configured to detect an impedance change caused by tank content or condensate which has passed through the central opening of the sealing gasket and collected in an annular space immediately surrounding the radially protruding collar portion.

A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

A profiled clamp having a clamp band and a clamping device which has two clamping jaws arranged at a distance (D) from one another in the circumferential direction (U). The clamping jaws are arranged on each end of the clamp band and can be moved towards one another by means of at least one clamping means. On an inner side of the clamp band, at least two profiled segments are arranged circumferentially spaced apart from one another. The profiled segments can be connected to the clamp band in each case by means of at least one latching connection.

Devices, systems, and methods are directed to automated techniques for fitting flanges to tubular sections used to form tubular structures, such as large-scale structures used in industrial applications (e.g., wind towers and pipelines). As compared to manual techniques for fitting flanges to tubular sections, the devices, systems, and methods of the present disclosure facilitate faster attachment of flanges, which may be useful for achieving cost-effective throughput. By way of further comparison to manual techniques, the devices, systems, and methods of the present disclosure may, further or instead, facilitate achieving tighter dimensional tolerances. In turn, such tighter dimensional tolerances may be useful for forming thinner-walled, lighter, and lower cost tubular structures. Still further or in the alternative, automated techniques for fitting flanges to tubular sections may facilitate attachment of multipiece flanges or other non-traditional flange geometries.

A thermal bridge forms a connection between a cold side and a hot side that is capable of withstanding a large temperature differential while high-pressure gas (e.g., air) flows between the two sides within an internal passageway. A cold-side region and hot-side region of the thermal bridge may each have a flange with a plurality of holes. The cold-side region may also include a conical fillet with counterbore recesses to provide access to each of the plurality of holes from a low radial position.

A wedge adapter seal may comprise a hard tube having a radially projecting flange and a wedge shaped body comprising a base flange and extending between a base flange face and a sealing face, wherein the hard tube is in fluid communication with the wedge shaped body with the radially projecting flange coupled proximate the sealing face. A wedge adapter seal may further comprise a ferrule coupled to the hard tube, wherein the ferrule comprises the radially projecting flange, a traveling flange disposed about the hard tube and configured to travel axially with respect to the hard tube, wherein the traveling flange comprises at least one of a triangular geometry having convex sides forming a Reuleaux triangle, a circular geometry, a rectangular geometry, a square geometry, or an oblique geometry.
