Calculate API RP 1102 pipeline diameter and wall thickness from pipe schedule.
The pressure design thickness equals the nominal wall thickness minus the corrosion allowance. The corrosion allowance includes mechanical allowances such as threads and damage etc. The fabrication tolerance is included in the design factor, and is not included in the pressure design thickness. Use the Result Table option display a table of pressure design wall thickness versus wall thickness for the selected diameter schedule.
