True or False: 1. Corrosion allowance should be considered on both sides of the tube sheet. ( ) 2. When grooves are made in the tube sheet and head, the metal that protrudes above the bottom surface of the partition groove can be used as a corrosion margin; however, when this corrosion margin is greater than the depth of the groove, the difference between the two values should also be added. ( ) Correct answer: 1. T 2. T

1. Corrosion allowance should be considered on both sides of the tube sheet. (Yes) 2. When grooves are made in the tube sheet and flat plates, the metal that protrudes above the bottom surface of the groove in the partition can be used as a corrosion margin; however, when this corrosion margin is greater than the depth of the groove, the difference between the two values should also be added. ( Right )
