Enter the thickness of the jacket used to withstand the internal pressure. If the thickness value of the jacket is not adequate to withstand the internal pressure, an acceptable thickness will be determined. Therefore, if the software is used for design purposes, enter a minimal value for jacket thickness. The software determines an appropriate pipe schedule through iteration.
The software-selected pipe schedules include a standard mill tolerance of 0.875 (a
reduction of 12.5%). This tolerance is not, however, be included in the user input
value of thickness. This allows you to include their own mill tolerance in their input
value, without having this value further adjusted.
