Question

Which of the following is/are the design rules for corrosion prevention?

(a) Weld rather than riveting containers

(b) Design systems for easy replacement of components that fails rapidly

(c) Avoid excessive mechanical stress and stress concentration

(d) Weld rather than riveting containers, design systems for easy replacements of components that fail rapidly, and avoid excessive mechanical stress and stress concentration

Answer 1

Correct choice is (d) Weld rather than riveting containers, design systems for easy replacements of components that fail rapidly, and avoid excessive mechanical stress and stress concentration

Easy explanation: Design rules for corrosion preventions:

Weld rather than the riveting tank and other containers

Design systems for easy replacements of components that fails rapidly

Avoid excessive mechanical stress and stress concentration

Avoid electrical contact between two dissimilar metals.
