A pipe having a pipe element for conveying a medium in a flow direction and having a flange element for connecting the pipe element to a connection partner. The pipe element has a pipe body with a media passage opening for conveying the medium in the flow direction. The flange element has a flange body with a media passage opening for conveying the medium in the flow direction. The flange element is arranged at one end of the pipe element in such a way that the media passage openings at least substantially overlap. The pipe has a sensor element which is arranged in the flange body in such a way that at least a portion of the sensor element can be in contact with the medium.

A contoured branch fitting for reducing stress in a header pipe caused by acoustic induced vibration that includes a maximum width, a maximum length, a thickness that is greater along the maximum length and a constant radius between the branch connection and the header connection.

A refrigerant hammer arrestor includes a housing having an internal compartment communicating with a refrigerant line, a piston received in the housing and dividing the internal compartment into a first chamber and a second chamber and a damping mechanism to dampen displacement of the piston within the housing. Various refrigerant loops are also described incorporating a refrigerant hammer arrestor.

A contoured branch fitting for reducing stress in a header pipe caused by acoustic induced vibration that includes a maximum width, a maximum length, a thickness that is greater along the maximum length and a constant radius between the branch connection and the header connection.

A tube wave reduction system for a borehole includes a tubular member; one or more openings in the tubular member, the one or more openings having a through-passage and a deformation region surrounding the through-passage; and an absorber in fluid communication with the one or more openings. Also included is a method for reducing an effect of a tube wave.

The present invention relates to a water piping system prevents degradation of water quality due to fluid remaining in a fuel tank for a long period of time and removes air and other impurities in a pressure tank and a pipe, and a method of controlling the same. The water piping system includes: a pump pressurizing fluid; a main pipe for delivering the fluid pressurized by the pump; a main valve disposed at an outlet port of the pump in the main pipe; a pressure tank connected to the main pipe; and a sub-pipe having a first end connected to a front side of the main valve of the main pipe and a second end connected to the pressure tank so that some of fluid pressurized and discharged from the pump is delivered to the pressure tank through the sub-pipe, thereby discharging substances in the pressure tank to the outside.

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 deceases 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 is be restricted or increased as may be desired.

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.
