(gage) psig, and a temperature of [_____] degrees C F.
2.2.1.1
High Pressure Steam Piping
**************************************************************************
NOTE: Specify Schedule 40 pipe for systems
operating at 862 kPa 125 pounds or less steam
pressure. For systems operating at pressures
greater than 862 kPa 125 pounds or where piping will
be subjected to high stress, determine pipe
thickness required and specify the appropriate pipe
schedule.
