Corrosion fatigue testing of flexible pipe armour wires requires specialist equipment and controls in order to simulate the conditions and service in a flexible pipe annulus. There has been a significant amount of testing collective studies and analysis performed over many years trying to establish design curves for flexible pipe armours however there are still areas of disagreement over some aspects of testing. This paper will provide a best practice guide to testing analyse and compare data from such testing and discuss those issues in dispute in order to draw conclusions on them based on controlled tests.Potential influences on test results include: frequency effects; performance of welds; the effect of iron saturation; the effect of testing with high partial pressures of CO2 in both sweet and sour environments; wire size effects and supplier variation (for the same specification of wire). Example comparisons and conclusions on each of these will be presented.
