CWP stands for Cold Working Pressure, and is
an indication of the pressure rating for piping, valves, and
fittings at a temperature range of -20 to +100F.
WOG (Water, Oil, Gas) is
an older standard that never applied a maximum temperature
requirement. As is apparent, higher temperatures can
significantly degrade pressure handling in piping systems.
Thus, CWP is the preferred standard
for communicating a fitting or valve's rated capacity.
