An inspection port system for a thermally insulated pipe, vessel, and the like is described. The inspection port system includes a base and a lid. The base defines a base plate with a central opening and a projecting sidewall projecting from a rim of the central opening. The projecting sidewall defines a tapered cylindrical inside surface. The lid defines a tapered cylindrical outside surface and includes a handle that can lock the lid to the base. The lid is dimensioned such that the tapered cylindrical outside surface can seal directly against the tapered cylindrical inside surface with the lid inserted into the base and the lid locked to the base by the handle. In use, the base may be attached to the jacket of the thermally insulated equipment and may provide a means of readily accessing the equipment for periodic inspection.

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.

A snubber includes a head portion, a shank portion, and a threaded portion. The shank portion is attached to the head portion, and the shank portion defines a shank diameter. The threaded portion is attached to the shank portion, and the threaded portion includes an external helical thread wrapped around a central shaft. The external helical thread defines a threaded diameter, and the central shaft defines a central shaft diameter. The shank diameter and the thread diameter are sized such that the shank portion and the threaded portion define at least one fluid flow path when the snubber is installed in a pressure sensor.

A sight glass assembly can be configured to permit viewing into an interior of a pipe fitting and can include a housing defining an inner housing surface, an outer housing surface, a first housing end, and an opposed second housing end, the inner housing surface defining a housing bore extending through the housing from the first housing end to the second housing end; an adapter defining an inner adapter surface, an outer adapter surface, a first adapter end coupled to the housing, and an opposed second adapter end configured to be coupled to the pipe fitting, the inner adapter surface defining an adapter bore extending through the adapter from the first adapter end to the second adapter end; and a transparent viewport positioned in the housing bore such that the interior of the pipe fitting is viewable through the housing bore, the viewport, and the adapter bore.

A module connection structure includes a first module, a second module connected to the first module via connectors, and fixing members that fix the second module to the first module. The fixing members are movable between a fixed position at which the second module is inseparable from the first module and an unfixed position at which the second module is separable from the first module. At least one of the first module and the second module has fixing member holders that hold the fixing members located at least at the unfixed position.

A remote seal system includes a remote diaphragm having a first side configured to be exposed to a process fluid. A conduit is coupled to the remote diaphragm and includes a fill fluid in fluidic communication with a second side of the remote diaphragm. A temperature sensor is thermally coupled to the conduit and configured to sense a temperature of the fill fluid. In one alternative example, a remote sensing assembly includes a flexible elongate conduit having a first end coupled to a remote diaphragm in fluidic communication with a process fluid and a second end extending a length from the first end to a process fluid pressure transmitter. A substantially incompressible fill fluid is disposed within the flexible elongate conduit. The process fluid pressure transmitter is configured to generate an output value indicative of pressure in the process fluid based on a corresponding pressure in the fill fluid. A temperature detector is coupled to the flexible elongate conduit and is configured to provide a signal indicative of an average temperature of the fill fluid along the flexible elongate conduit. A compensation system calculates a thermal expansion value based on the average temperature and adjusts the pressure signal based on the thermal expansion value.

A missile flow line is assembled in a frac manifold to manifold the discharge from a plurality of pumps. The missile comprises at least two junction fittings joined by a flange union to at least one spooled pipe to form a conduit. The junction fittings comprise a fitting body having a primary bore and at least two feed bores. The primary bore extends axially through the body between primary union faces adapted for connection to a flowline component by a flange union. The feed bores extend radially through the body from a feed union face to an intersection with the primary bore. The feed union faces are adapted for connection to pump discharge lines by a flange union. The intersections of the feed bores with the primary bore are offset axially from each other along the primary bore.

A quick connect fluid connector that is detachably connectable to a fluid system to process a gas into or from the fluid system through the quick connect fluid connector. The quick connect fluid connector includes one or more temperature sensors that can sense the temperature of the gas within the fluid connector during processing. Based on the sensed temperature(s), an alert can be generated to alert a human operator conducting the processing and/or automatically shut-off the processing if the sensed temperature becomes too high. The operator will therefore be alerted if the cylinders are being processed too quickly or if the processing duration could be shortened.

A pipe clamp is used to connect pipe ends together and thereby establish a pipe joint. The pipe clamp and pipe joint are designed and constructed to accommodate a sensor bung and/or a sensor equipped at one of the connected pipe ends. The pipe clamp and pipe joint can be of an automotive exhaust application.

A system for detecting a leak in a duct is disclosed, including a sheath covering a duct section, a fluid concentrating device and a sensor. The sheath is attached to a boundary portion of the duct section and forms an inner space between an outer surface of the duct section and the sheath. The fluid concentrating device has an opening through the sheath connecting the inner space to an external space outside the sheath. The inner space is sealed except for the opening through the sheath. The sensor is stationed outside the opening of the fluid concentrating device and is configured to detect fluid flow from the inner space through the opening at a level corresponding to a duct leak in a pre-burst condition.
