Case Study $5$

Wear issues are commonly encountered in the oil and gas industry. Consider the following

components in the two cases below.

Case$-$A: Pipe elbow that conveys a high

flow of dry gas loaded with sand.

Case$-$B: Sliding contact between metal

surfaces results in gouging.

$($a$)$ Identify the types of wear damage and provide an illustrative sketch for each case,

respectively.

$($b$)$ Explain the damage mechanisms in part $($a$),$ and their key characteristics.

$($c$)$ Suggest prevention methods to minimize wear damage for each case.

$($d$)$ Predict the likely outcome for the wear damage in Case $A$ if the gas is replaced with a

corrosive fluid. Illustrate your answer with a sketch and provide justification.
