valves and other piping fittings
/.Nominal Pipe Size (NPS) - Answer-✅"An approximate indication of pipe diameter.
- Up to and including DN 300 (NPS 12), the number represents the nominal ouside
diameter of the pipe
,- For DN 350 (NPS 14) and larger pipe, the number represents the actual outside
diameter of the pipe."
/.Non-Return Stop Valve - Answer-✅A type of globe valve with a plug that moves
independently of the valve spindle when the valve is in the open position, permitting it to
act as a check valve if fluid reversal occurs. This valve is commonly used on boiler main
steam outlets
/.Pipe Die - Answer-✅A cutting tool used to create the male threads on a pipe
/.Pipe Reamer - Answer-✅A tool used to remove the internal burr left by a displacement
cutter
/.Pipe Tap - Answer-✅A cutting tool used to cut female threads for pipe fittings
/.Plug Fitting - Answer-✅A pipe fitting with external threads, used to close off an unused
opening in a pipe fitting
/.Plug Valve - Answer-✅A lubricated quarter-turn valve containing a tapered conical
flow element, that when rotated regulates the flow of fluid through the valve. These
valves are common in natural gas service
/.Pressure Reducing Station (PRS) - Answer-✅A piping system comprised of a number
of components, that receives a high pressure process fluid (such as steam) and lowers
the pressure so that the process fluid is suitable for using with downstream equipment.
The main components include a pressure reducing valve (PRV), pressure gauges,
isolating valves, a bypass valve, a strainer, unions, a sensing line downstream of the
PRV, and a safety valve. In stream service, the piping is equipped with steam traps
/.Pressure Reducing Valves (PRV) - Answer-✅A device that lowers the pressure of a
process fluid to a desired downstream pressure setpoint, regardless of fluctuations in
upstream pressure or flow conditions
/.Reducer Fitting - Answer-✅A device used to connect pipes of different diameters
/.Return Bends - Answer-✅A pipe fitting used for reversing direction of a pipe run by
180 degrees
/.Ring Joint Gasket - Answer-✅A gasket that fits in a grooved flange face
/.Schedule Number - Answer-✅A number that represents pipe wall thickness
/.Socket Welded Fitting - Answer-✅A fitting, such as a valve, fitting or flange, that has a
recess to permit insertion of a pipe prior to it being welded into place
, /.Steam Seperator - Answer-✅A device installed in a stream line to remove moisture
droplets and other suspended impurities from the steam, by forcing the steam to change
direction
/.Steam Trap - Answer-✅An automatic valve that drains condensate from a steam-
containing enclosure while remaining tight to live steam, or if necessary, allowing steam
to flow at a controlled or adjusted rate. Most will also pass non-condensable gases
which remaining tight to live steam. ANSI/FCI 69-1-1989
/.Tee - Answer-✅Pipe fitting used for making a branch line connection at 90 degrees.
Reducing tees may have different sized openings for reducing the size of the pipes for
the inlet, branch, or outlet of the tee
/.Thermodynamic Trap - Answer-✅A steam trap that operates based on the difference
between the heat energy of the steam and that of the condensate
/.Thermostatic Trap - Answer-✅A steam trap that operates based on the difference
between the temperature of the steam and that of the condensate
/.Union - Answer-✅A pipe fitting with two female threaded ends and a threaded
connector nut in the middle. Used to allow easy assembly and disassembly of piping
connections

usually consists of a valve seat, valve disc or gate, valve stem, and guide bushings
/.Van Stone Flange - Answer-✅A flange that fits loosely on the end of a pipe, so that
sections of pipe can be more easily aligned during assembly

by longterm throttling of process fluid, that prevents shut valves from completely
stopping fluid flow. It has the appearance of "cuts" on the valve trim surface
