What Is A Common Failure Mechanism For Above Ground Atmospheric Storage Tanks? |
|
Answer» Tanks CONSTRUCTED prior to the 1950's are notorious for failing along the shell-to-bottom seam or on the side seam. The PRINCIPLE reason for this is that these tanks were constructed before there were established procedures and codes for such a tank (Ex/ API-650 "WELDED Steel Tanks for Oil Storage"). ONE of the key features of these codes and procedures was to make sure that tanks were designed to FAIL along the shell-to-seam such that the liquid remained largely contained.
