A penetration seal and its installation method for use with a pipe extending through an opening, or penetration, in a vessel, such as a boiler, containing fluid. A first collar surrounds the pipe adjacent the vessel and is in fluid communication with the opening in the vessel. A second collar has a sleeve portion engaging the exterior of the pipe and is spaced from the first collar. An insulation pillow substantially surrounds the pipe and is connected to the first and second collars. An expansion sleeve substantially surrounds the insulation pillow and is connected to the first and second collars, wherein the sleeve portion of the second collar is configured to compressively engage the exterior surface of the pipe sufficiently to frictionally fix the second sleeve against movement relative to the pipe.

An electrolysis facility having a sealed coupling between at least two pipes may be mountable on one another. The sealed coupling may be formed on at least one overlapping pipe pair by lateral surfaces abutting one another. The pipes may be mounted/mountable one inside the other in a floating manner relative to one another in an axial direction. A deformation point may be formed at a circumferential position having an axial length on a free end of the outer pipe in the overlap region. The deformation point may define a region for deformation of the outer pipe. A lateral surface of an inner lateral surface of the outer pipe and an outer lateral surface of the inner pipe may define a sealing surface that overlaps the deformation point in the axial direction. In addition to high operational reliability, this also enables a simplification of the installation procedure.

In order to allow for thermal elongation of a liner, a pipe member, in the interior of which flows a fluid containing solids, is provided with: a tubular outer pipe; a single tubular liner provided inside the outer pipe with a gap therebetween in the radial direction, or a plurality thereof arranged serially in the direction of the pipe axis C; a refractory material filled in between the outer pipe and the liner; a first liner holding member that is provided on an end portion side of the outer pipe, and that holds the liner arranged on the end portion side in a restrained state in the pipe axis C direction and the circumferential direction around the pipe axis C; and a second liner holding member that is provided on an end portion side of the outer pipe, and that holds the liner arranged on the end portion side.

A flange connection has two flanges and a weld ring gasket arranged between the flanges, wherein the weld ring gasket has two weld ring halves arranged one on top of the other, each having a base section and a lip arranged on it, wherein the weld ring halves are welded to the base section by way of a fillet weld with the flange that lies against it, and wherein the lips form a torus-shaped connection section having a hollow interior, and the weld ring halves are welded to one another at the torus-shaped connection section, by way of a caulking seam. The torus-shaped connection section is arranged to lie radially on the inside.

The disclosure relates to a conduit connector for a fluid line, having a housing, which has at least one first connection geometry and one second connection geometry, each for connecting to a fluid line. In the housing, a fluid-conducting channel is formed between the first connection geometry and the second connection geometry. In order to avoid damage due to freezing of a liquid located in the channel or the connected fluid lines, the housing has a volume equalization device, which is connected to the channel.

A valve support apparatus is disclosed as capable of shifting a valve in a piping system in accordance with the thermal expansion of connected piping. The apparatus includes a valve mount, a slide mount, and a base, wherein the valve mount contains a valve attachment assembly to attach a valve. The valve mount can couple with the slide mount, using a mounting assembly, such that the valve mount is vertically and laterally secured about the slide mount, but the valve mount can move along the longitudinal axis of the slide mount. The slide mount, using another mounting assembly, can couple with the base, such that the slide mount is vertically and laterally secured about the base, but the slide mount can move along the longitudinal axis of the base, which is oriented orthogonally to the longitudinal axis of the slide mount. With this configuration, the stress and other loads exerted on the valve due to thermal expansion can be minimized by allowing the valve to be moved to account for the elongated piping.

A connection unit having a connector and at least one fluid line that is connected to the connector, wherein the connector has at least two connection ends and a connector section that connects the connection ends to one another. A fluid line end of a fluid line engages with at least one connection end of the connector. At least one compensation element is connected to the fluid line in the area of the fluid line end of the fluid line, the compensation element being supportable on at least one support stop via at least one spring element. Due to a pressure increase in the connector section, the compensation element is movable against the restoring force of the spring element in the direction of the support stop, with an increase in the internal volume of the connector section.
