The present invention relates to a pipe (1, 3) having a pipe element (3) for conveying a medium in a flow direction (A) and having a flange element (1) for connecting the pipe element (3) to a connection partner, wherein the pipe element (3) has a pipe body (30) with a media passage opening (31) for conveying the medium in the flow direction (A), wherein the flange element (1) has a flange body (10) with a media passage opening (11) for conveying the medium in the flow direction (A), wherein the flange element (1) is arranged at one end of the pipe element (3) in such a way that the media passage openings (11, 31) at least substantially overlap. The pipe (1, 3) is characterized by a sensor element (21) which is arranged in the flange body (10) in such a way that at least a portion of the sensor element (21) can be in contact with the medium.

A fluid pulse dampener with automatic pressure-compensation is provided. A system of chambers and channels in the dampener creates an internal feedback mechanism that increases or decreases a compensating pressure on the membrane in response to increases or decreases in the pressure of a fluid moving past the other side of the membrane. Variations of the pulse dampener allow for the input and/or output of gas flow to be restricted or increased as may be desired.

Disclosed is an absorber system for absorbing pressure shocks and fluid volume shocks in a fluid system. In particular, the absorber system includes a housing with a joint for insertion within a fluid system, wherein the housing interior is in fluid communication with fluid in the fluid system. As such, when a pressure and/or fluid volume shock is developed within the fluid system, fluid is forced into the housing via the joint. A membrane is disposed within the housing in such a way that the fluid impacts the membrane which, in response, flexes to absorb and control the pressure and/or fluid volume shock within the fluid system. The absorber system, thus, controls pressure and/or fluid volume shock within a system and can prevent water hammer and other problems which can result from the development of pressure and/or fluid volume shock.

A modular stabilizer is provided for a reciprocating pump. The modular stabilizer includes at least one fluid dampening module incorporating a dampening material and forming a second fluid flow path in fluid communication with the first fluid flow path defined between the entry ports of the suction manifold. The second fluid flow path is an alternate fluid flow path branching from the first fluid flow path.

A shower system includes a shower waterway and a fluid control valve. The shower waterway is configured to be coupled to a shower device. The fluid control valve is coupled to the shower waterway and comprises a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably coupled to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a water pressure fluctuation in the shower waterway.

Disclosed are processes, devices and systems for preventing overpressurization of subsea production equipment and flowlines in which fluid passes through a high integrity pressure protection system (HIPPS). In embodiments, a container having a piston seal therein can be attached to the piping. In embodiments, a device having a piston seal therein and connected to a fluid receptacle can be attached to the piping. In the event of a pressure surge, fluid can be diverted to the container or the device, thereby lessening the pressure surge. In embodiments, the container or device includes a resetting force to return the piston seal to its original sealed position. The use of the systems disclosed improve the life of the HIPPS valve, protects subsea equipment and flowlines, and enables a length and/or a wall thickness of a fortified pipeline zone downstream of the HIPPS to be reduced.

An attenuator for high pressure fluid systems includes a shielding stud including first and second ends and a cylindrical space extending therebetween. The attenuator comprises a cylindrical, attenuator body disposed within the cylindrical space and defining a pressure chamber therein. First and second seal heads are positioned within first and second ends of said shielding stud and coupled to the attenuator body using a tensioner assembly and a plug threadingly coupled to first and second inner threaded surfaces of the shielding stud in first and second ends thereof.

A pressure fluctuation damper for a metering instrument (10) located at an end of a pulse tube (9), which comprises a generally elongated cylindrical element (2) comprising one or more intake throttling channels (4) in fluid communication with the pulse tube (9) and one or more outlet damping channels (5) in fluid communication with the metering instrument (10), the elongated cylindrical element (2) being equipped with an end face thrust element (3) located coaxially to the pulse tube (9), the diameter of the elongated cylindrical element (2) being smaller than the inner diameter of the pulse tube (9) and the diameter of the end face thrust element (3) being larger than the inner diameter of the pulse tube (9); and a method for mounting the pressure fluctuation damper.
