Effects of hydrostatic retests on stress-corrosion cracking

OSTI ID:6938855
Concern over the possibility that hydrostatic retesting may initiate or activate stress-corrosion cracks in a pipe prompted Battelle Columbus Laboratories to determine the effect of retest conditions on the future growth of any remaining stress-corrosion cracks. Laboratory data so far confirm that the most detrimental effects from the retest is the reinitiation or initiation of stress-corrosion cracks from a relatively short, deep defect that could result in a leak-type failure. Further studies at Battelle are aimed at defining the best retest pressures and hold times for avoiding this effect. Despite this drawback, hydrostatic retesting remains the most reliable method available for locating and removing stress-corrosion cracks in an operating pipeline.
