User Defined Outside Diameter schedtype: The steps in the development and the background for the methods are described in this paper. Use the result table option on the calc bar to display the pipe schedule with nominal wall thickness, minimum wall thickness and pressure design wall thickness for the selected diameter.
Calculate pipeline defect interaction length and interaction angle, and projection line minimum length, minimum overlap and projection line angular spacing DNVGL-RP-F section 3. The second approach is based on the allowable stress design format, where ff101 allowable operating pressure is determined from the capacity and multiplied with a single usage factor based on the original design factor.
