Question

Which of the following is the design rule to reduce erosion-corrosion?

(a) Avoid excessive mechanical stress

(b) Avoid sharp bend in piping systems

(c) Avoid sharp bends in piping systems and provide thicker sections to reduce impingement effects

(d) Avoid sharp bends in the piping system and excessive mechanical stress

The question was asked in an internship interview.

Asked question is from Prevention topic in chapter Corrosion Prevention of Corrosion Engineering

Answer 1

The correct answer is (c) Avoid sharp bends in piping systems and provide thicker sections to reduce impingement effects

Easy explanation: Erosion corrosion can be minimized by avoiding sharp bends in the piping system and provide a thicker section to reduce impingement effects. And the better material selection is also one of the factors to prevent erosion-corrosion.
