Although failure always happens, the main issue is if it occurs prematurely. Our engineering team has the experience to determine the root cause and provide solutions from recurring. During our failure investigation, we observe typical failure mode in the materials and perfore materials testing, chemical analysis, mechanical testing and materials characterization. Our failure analysis experts evaluate failure from many different industries, one of them is the oil and gas industry.
In the oil and gas industry, one of the most common types of failure of the equipment is Hydrogen embrittlement. It happens to vessels, pipes, and various reactors. The degree of embrittlement is influenced by the type of the alloy, the mechanical properties of the alloy, its microstructure and the amount of residual stress. The phenomenon of Hydrogen embrittlement can lead to failure mechanisms which can cause surface or subsurface cracks:

• Blistering
• Hydrogen Induced Cracking (HIC)
• Stress Oriented Hydrogen Induced Cracking (SOHIC)
• Sulfide Stress Cracking (SSC)
• Hydrogen  Cyanide (HCN)
• HighTemperature Hydrogen Attack(HTHA)
• Hydrogen Embrittlement(HE
