API 620 Tank Standard Post-heat Treatment (Stress Relief)The post-heat treatment now performed on pressure vessels is of established value, although the mechanism by which the improvement is realized may be open to debate. Post-heat treatment of NM500 grade material tank sections when the plate thickness exceeds 11/4 in. is required as stated in 5.25. In special cases, the possibilities of post-heat treatment after erection should be explored. Post-heating an insulated tank may be possible if an ample source of heat is readily available and if the rigidity of the tank is adequate.The thermal stress-relief treatment performed on pressure vessels is recognized as a means for reducing the probability of brittle failures.
