RP-F describes two alternative approaches with different safety philosophy. Pipe Outside Diameter tn: See the latest News And Updates.

DNVGL-RP-F Corroded pipelines – DNV GL

Uncertainties associated with the sizing of the defect and the specification of the material properties are specifically considered in determination of the allowable operating pressure.

Wall Thickness Fabrication Tolerance Type tfu: User Defined Outside Diameter schedtype: Publishers Content Coverage Privacy. About us Contact us Help Terms of use. Pressure Design Wall Thickness xf: 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.

Rock Mechanics Symposium and 5th U. 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. Measured Outside Circumference ODu: Wall Thickness Fabrication Allowance tm: 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.

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. Log in to your subscription Username.
