Failure Mechanics Flashcards
1
Q
What is Sulfide Stress Cracking (SSC)?
A
SSC is a type of brittle failure in metals caused by hydrogen sulfide (H2S), common in sour gas wells, requiring careful material selection to avoid failures.
2
Q
What is Hydrogen Induced Cracking (HIC)?
A
HIC occurs when hydrogen penetrates steel, causing internal cracks, typically in environments with high H2S concentrations.
3
Q
What is corrosion fatigue?
A
Corrosion fatigue is the weakening of metal due to combined stress and corrosion, which makes it more prone to cracking over time.
4
Q
What kind of failure analysis does Blade perform?
A
Blade performs metallurgical testing, corrosion investigations, fracture mechanics testing, and accelerated testing to determine the root cause of component failures.
