SECTION 5 - BRITTLE FRACTURE CONSIDERATIONS 5.1 General Provides a procedure to assess the risk of failure due to brittle fracture, plus establishes general guidance for avoiding this type failure. Now there is an eleven (11) step assessment procedure. 5.2 Basic Considerations See Fig. 5-1 "Decision Tree" as the assessment procedure to determine failure potential. Prior incident data whereby brittle fracture has occurred either shortly after erection during hydrostatic testing or on the first filling in cold weather, after a change to lower temperature service, or after a repair/alteration. This failure has primarily occurred in welded tanks. Charlie Chong/ Fion Zhang
5.2.1 Reported conditions involving failures (primarily involving welded tanks): a. Hydro test at initial erection. b. First filling in cold weather. c. After a change to lower temperature service. d. After a repair-alteration. 5.2.2 Any change in service must be evaluated to determine if it increases the risk of failure due to brittle fracture. For example, the change to a more severe service involving one of the following: a. Lower operating temperature (especially below 60°F). b. Product with a higher specific gravity. * Consider need for hydrostatic test when any repair or alteration does not meet all requirements of the 653 standard or deterioration of the tank has occurred since the original hydrostatic test.
