Which of the following is/are included in the general term avoid heterogeneity? |
| A. | Dissimilar metal contact |
| B. | Different phases such as vapor spaces |
| C. | Uneven heat and stress contribution |
| D. | Dissimilar metal contact, different phases such as vapor spaces, and uneven heat and stress distribution. |

| B. | Specify operating and maintenance procedures |
| C. | Tank bottoms should be sloped toward drain holes |
| D. | Avoid electrical contact between dissimilar metals |
| Answer» B. Specify operating and maintenance procedures | |
| 4. |
Which of the following is the design rule to reduce erosion-corrosion? |
| A. | Avoid excessive mechanical stress |
| B. | Avoid sharp bend in piping systems |
