Calculate DNVGL-RP-O501 pipe internal diameter and pressure design wall thickness from pipe schedule.
The pressure design thickness equals the nominal wall thickness minus the corrosion allowance and fabrication allowance. The minimum wall thickness equals the nominal wall thickness minus the fabrication allowance. The corrosion allowance includes mechanical allowances such as threads and damage etc. Use the Result Table option display a table of diameter and wall thickness versus nominal wall thickness for the selected diameter schedule.
