1. Calculate the minimum design wall thickness (MWT) of a seamless carbon steel tube of SA-192 material that is rolled (expanded) into an opening in the drum shell. The outside diameter of the tube is 2.25 inches. The average tube metal temperature is 1000 deg F, and the design pressure is 1000psig. 2. For the MWT calculated in Problem #1, what is the tube gauge that will meet that specified thickness? 3. If the tube gauge selected in Problem #2 is placed in service in the boiler and is exposed to erosion from a steam leak, what would the new design pressure of the tube be if its wall thickness was reduced by 50%? 1.
