A pipe rehabilitation system and/or robot can be used inside a pipe to measure characteristics of branch conduits, install plugs into branch conduits before the pipe is lined with a liner, remove portions of plugs and liners after lining to restore fluid communication between the pipe and branch conduits, and/or install fittings into the branch conduits to connect the liner to the branch conduits. A probe can measure characteristics of a branch conduit. A tool can install plugs and/or fittings into the branch conduits. A linkage can connect a tool to a robotic tractor so that the connected elements can navigate through a main pipe. A visualization system can aid in aligning a robot with a branch conduit. Height-adjustable braces can support robotic tools in a pipe. A plug can include integrated locating features and/or movable parts that enable expanding the plug to seal with the branch conduit.

An interface adapted for connecting a fluid measurement point includes a body including at least two connection locations, wherein the body has fluid ducts, each of which has a connection location, wherein the fluid ducts have at their connection locations first duct axes, wherein the connection locations are especially coplanar, wherein the connection locations are adapted for connecting process connectors from a connection direction for sealed communication with the fluid ducts, wherein the fluid ducts are adapted via the process connectors to supply, and drain, a medium, respectively, to and from the fluid measurement point, wherein the interface has at least one holding element for releasably securing at least one process connector to the body, wherein the holding element has at least one process connector seat, wherein the holding element is adapted to be moved into an end position (EP) effecting the securement.

The present disclosure provides a pressure measuring instrument which comprises a gauge body, a connecting component and a pushing component, the connecting component comprises a first connecting member and a positioning sleeve which are connected with each other to form a corotating relationship, and the first connecting member comprises a first external thread section and a second external thread section connected to each other, and the first external thread section is used for a pressure-measuring hole threaded with a pressure vessel, the second external thread section protrudes from the pressure-measuring hole, the positioning sleeve is rotatably screwed to the second external thread section, and the positioning sleeve is configured to provide a force to the pressure vessel, and the pushing component is configured to pass through the connecting component and be pushed by a fluid in the pressure-measuring hole to push against a pressurize unit of the gauge body.

An elbow screw joint system for screw-connecting and rerouting elongate shaped parts includes a guiding body, an insert and a cover. The insert has a guiding section rotatably arranged at least partially inside the guiding body. The guiding body has a guiding recess and an outlet recess. The guiding recess has a guiding axis and extends along the guiding axis from a receiving side to an opposite head side. The outlet recess has an outlet axis and extends from an outlet side, along the outlet axis, to the guiding recess. Also, the guiding axis and the outlet axis are at an angle relative to one another. The guiding section has a screw thread at an upper end region which is associated with the head side of the guiding body, and the cover is screw-connected, from the head side, to the screw thread of the guiding section.

A sensor housing (1) including a longitudinal axis (2), a clamping area (3) surrounding the longitudinal axis (2) and a recess (4) in the clamping area (3) is described, the recess (4) running in circumferential direction. In such a sensor housing a recess in the clamping area (3) should be provided with low production costs. To this end the recess (4) is formed between a part 6 of the housing (1) and a locking element (5) fixed to the housing (1).

A split retaining ring for a connection assembly adapted for connecting an instrument or other device to a vessel, such as a pressure vessel. The connection assembly includes a base, an instrument or device, and a split retaining ring wherein the split retaining ring includes overlapping end portions. The split retaining ring also includes an annular rib adapted for engaging a ferrule of the instrument or device in order to substantially sealing engage the instrument or device to the base.

A snap fitting for use in plumbing is provided. The snap fitting includes a main body formed of plastic and shaped to extend partially around a cylindrical pipe to snap over the pipe and an inset for extending from an interior side of the main body into a hole in the cylindrical pipe.
