-Mill Tol %

Displays the negative mill tolerance. This value is read from the configuration file and used in minimum wall thickness calculations. Also, for IGE/TD/12, this value is used when the Base Stress/Flexibility On option of the Special Execution Options is set to Plus Mill Tolerance. In that case, piping stiffness and section modulus is based on the nominal wall thickness, decreased by this percentage. You can change this value on an element-by-element basis.

Tvar %

Specifies the percentage variation of the reinforced pipe wall thickness.

The minimum reinforced pipe wall thickness (t) = Wt(1 - Tvar%). For more information on Wt, see Wt/Sch.
