Influence of corrosion on casing strength
Corrosion can pose a major threat to the installations whether above or below ground. With particular respect to casing, corrosion can impair the ability of the casing to perform its functions in two ways. Firstly, metal loss will reduce the wall thickness of the casing and hence its capacity to withstand the design loads. Secondly, corrosion can weaken the casing material so that it can no longer withstand the design loads.
The management of this threat is dependent on the following factors:
- the awareness of . . .
