In Version 17, in Design Parameters, Hydraulic Parameters, and Rationalization Parameters, I see the ability to use zone and mainline pipe pressure ratings in the design process. I know the pressure ratings are located in the pipe database. My question is, what pressure for a particular pipe in the pipe database field "Allowable Pressure" do I enter, and how is that number used in the rationalization process. For example, if I put an allowable pressure of 100 psi in the database, does the rationalization process switch to a heavier walled pipe at 100 psi, or at a percentage of 100 psi?

Hi Steve,

There is no tolerance built into this setting, therefore if your allowable pressure is set to 100psi then any pipe pressures greater than 100psi will cause an automatic change to a suitable pipe size rated at over 100psi during LP or Velocity designing.
