STRESS CORROSION TESTING ON THERMALLY-INSULATED STAINLESS STEEL PIPING
Thermally-insulated Type 304 stainless steel piping was exposed to conditions more conducive to stress corrosion cracking than those of actual service, and the possible effectiveness was investigated of aluminum in contact with stainless steel as an inhibitor to stress corrosion attack. Four test loops were built and operated for 500 hours and then were metallurgically examined. No stress corrosion cracking was detected in any of the sections examined, although intergranular corrosion to a depth of 0.0015 inch was seen in one straight leg section adjacent to a weld. This was concluded to be a structure-sensitive phenomenon. There was no evidence of either an inhibiting or accelerating effect on corrosion provided by the aluminum foil or wire used as wrapping for the piping of two of the test loops.
