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.

The present embodiments relate to a novel clamping assembly. More specifically, present embodiments relate to a clamping assembly for blind flange installation which provides an air tight seal for piping applications including, but not limited to, low pressure high-density polyethylene (HDPE) piping applications.

An assembly 10 includes a coupling member 12 having a first annular, radial connection flange 22 and a blanking cap 14 comprising a disc-like member 30 which defines a second, corresponding annular, radial connection flange 34. The connecting flanges are clamped together by a clamp (16) with a seal member 18 in-between. The blanking cap comprises a pair of safety lugs 62 attached to the disc-like member which each extend about an outer circumferential periphery of the first connection flange 22. Each safety lug has an abutment 68 for engagement with the first connection flange to limit axial movement of the disc-like member away from the coupling member. The lugs 62 prevent the blanking cap from flying off in the event the clamp is released whilst the interior of the coupling member is pressurised. The lugs 62 may each have a stop member 66 which defines the abutment and which may take the form of an elongate curved member extending circumferentially about an axis of the connection flanges. The clamp may be tri-clamp.

A sealing assembly for flanges is described. The sealing assembly includes a wedge, a first sealing element, a second sealing element, and a fastener. The wedge has a first surface, a second surface, and a third surface. The first surface defines a pressure void with a first flange and a second flange. The first sealing element engages the second surface of the wedge and the first flange. The second sealing element engages the third surface of the wedge and the second flange. The fastener couples the first sealing element, the first flange, the second flange, and the second sealing element together. The wedge slides toward the sealing elements responsive to a pressure increase in the pressure void. The sealing elements force the flanges toward each other responsive to the wedge sliding toward the first sealing element and the second sealing element.

The present invention relates to a device 100 for connecting a gas-conducting conduit element 1, in particular a hydrogen-conducting conduit element, to a counterpart 2, in particular a component, comprising: at least one screw body 10, which is configured to be brought into tight engagement, in particular into gas-tight engagement, with the counterpart 2; a first seal 3, which is in the form of a valve body 3a which is configured to be brought into contact, in particular into gas-tight contact, with a valve seat 4 provided on the counterpart 2, or which is in the form of a flat seal; and a second seal 5 which operates on a sealing effect principle according to which the sealing effect is exerted or deployed irrespective of an axial displacement, in particular in an installation direction E, which is necessary for creating the sealing effect of the first seal 3.

A decompression heat-insulating pipe structure that can exhibit the desired heat-insulating performance and is easy to assemble. In the structure, a space between ends of inner and outer tubes is decompressed. The outer tube includes a first flange, which extends radially inward from an axially one end thereof, and a second flange, which extends radially outward from the axially other end thereof. The inner tube includes a third flange, which extends radially inward from an axially one end thereof and is opposed to the first flange at an axially inward position of the first flange, and a fourth flange, which extends radially outward from the axially other end thereof and being opposed to the second flange at an axially outward position of the second flange. First and second elastic seal members are disposed between the first and third flanges and between the second and fourth flanges, respectively.

A manifold assembly configured for use with a fluid end used in oil and gas operations. The manifold assembly comprises upper and lower manifolds supported on side posts such that the manifolds and posts define a central opening. In operation, the fluid end is positioned within the central opening such that the manifold assembly surrounds the fluid end. The manifold assembly is not attached to the fluid end other than flexible conduits interconnecting the fluid and the manifolds. The manifold assembly is modular and when assembled, may be moved together as a single unit.
