Currently, a number of fracture mechanics-based methods are available for crack assessment. In this paper, a critical review is given to failure assessment diagram (FAD), in particular the API 579-2000 fracture mechanics assessment method for crack-like flaws. Illustrations, arranged by applicability to field examples, demonstrate the approach.
As a result of a Carbonate Stress Corrosion Cracking (CSCC) event at one refinery an investigation was made into the cause and mitigation of CSCC. This paper outlines the information obtained and the development of tools that could be utilized by other refinery fluidized catalytic cracker units (FCCU's) to better assess risk of CSCC.
A corrosion cracking assessment evaluated a 13Cr-5Ni-2Mo 110 ksi grade martensitic stainless steel as a potential well tubing material for oil and gas production from Gulf of Mexico reservoirs. Also, Stress Corrosion Cracking at low H2S/low temp/high acidity (pH<3.5) was tested by Cyclic Slow Strain Rate.
Methods used to destructively determine the actual crack depths in the Pipeline Research Council International project as well as the statistical comparison of those values to the NDE measurements. We also briefly introduce advanced fracture mechanics analysis techniques that can be used to assess the safety significance of crack-like pipeline anomalies.
This paper will detail the environmental cracking test program and results when Alloy UNS S42028 (For applications such as high collapse liners sections in high pressure high temperature (HPHT) reservoirs) was exposed to medium density bromide based clear brine fluids at a temperature of 150oC (302oF).
Supercritical water-cooled reactor (SCWR) is an innovative Generation IV nuclear reactor. Nickel-based alloys, such as UNS N06625, UNS R20033 and UNS N07214 alloys, are selected for the fuel cladding. Knowledge gaps exist as regards their use for the fuel cladding in the SCWR. This paper introduces laboratory results on corrosion and stress corrosion cracking (SCC) of the nickel-based alloys.
