The measured pipe diameter and wall thickness should be used if it is available.

Nominal Wall Thickness tp: The steps in the development and the background for the methods are described in this paper. The first approach includes calibrated safety factors, taking into account the natural spread in material properties and wall thickness and internal pressure variations.

Several oil dv and regulating authorities have sponsored the development of the RP. Nominal Inside Diameter OD: Rock Mechanics Symposium and 5th U. Either the nominal wall thickness, pressure design wall thickness nominal wall thickness minus fabrication allowance and corrosion allowanceor minimum wall thickness nominal wall thickness minus fabrication allowance can be used depending on the condition of the pipe engineering judgement is required.

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. Pipe diameter is generally measured from the circumference.
