摘要

The invention relates to a testing setup to determine the effect of residual stresses in thin walled stainless steel tubes used in chloride media on the stress corrosion cracking CHARACTERISTICS, comprising at least two stainless steel plates disposed at a spaced-apart position to allow disposition of the tube sample to be tested, the slit of the tube located at 90° in respect of the two opposite points of contact; pieces of oxidized Zircaloy-4 interposed between the tube sample and the stainless steel plates, and a fastening means for releasably fastening the tube sample onto the testing device which is gradually rotatable to tighten the tube sample, wherein the deflection produced on the tube sample corresponding to tightening of the fastening means, and wherein the residual stress is calculated corresponding to the value of said deflection.
