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…

Influence of wear on casing strength

The burst, collapse and axial strengths of casing are directly related to wall thickness, and hence are reduced by wear. The casing must be designed so that wear will not reduce the strength of the…

Influence of fatigue on casing strength

Casing failure can have various causes. Casing may fail after exceeding, even once, the ultimate tensile or compressive strength, but also after repeated load cycles below the ultimate tensile or…
