Line Pipe Wall Thickness And Diameter

Calculate pipe nominal wall thickness, minimum wall thickness and pressure design wall thickness from pipe schedule diameter and wall thickness.

For most pipeline codes the pressure design thickness equals the nominal wall thickness minus the fabrication allowance and the corrosion allowance (use the with tolerance calculator). For some codes the fbrication allowance is ignored and the pressure design thickness equals the nominal wall thickness minus the corrosion allowance.

Use the Result Table option to display the results for the selected pipe schedule and pipe diameter.
