The second approach is based on the allowable stress design format, where the allowable operating pressure is determined from the capacity and multiplied with a single usage factor based on the original design factor.

Pipe Outside Circumference OD: Wall Thickness Fabrication Tolerance Type tfu: Advanced search Show search help. Several oil companies and regulating authorities have sponsored the development of the RP.
In this paper the development of the RP is outlined, the determination of the safety factors are explained and the sensitivity of the safety level to the various parameters is demonstrated. Uncertainties associated with the sizing of the defect and the gp of the material properties are specifically considered in determination of the allowable operating pressure.
F10 first approach includes calibrated safety factors, taking into account the natural spread in material properties and wall thickness and internal pressure variations.

The measured pipe diameter and wall thickness should be used if it is available. The development of the capacity equations and acceptance equations giving the allowable operating pressure and the development of the safety factors are described in this paper.
