Standardized Corrosion Testing - Southwest Research Institute

SouthwestResearchInstitute ®KeywordsStandardized Corrosion TestingSouthwest Research Institute® (SwRI®) hasover 20 years of experience in addressingindustrial corrosion problems. SwRI hasextensive test facilities and state-of-the-artinstrumentation to assess all aspects of corrosionand materials failure. Corrosionresearch is supported by a multidisciplinarygroup of engineers, scientists and technicalstaff who offer a comprehensive approach tosolving corrosion problems in governmentand industry.ElectrochemicalTestingAtmosphericCorrosionTestingCoatingsPerformanceMaterials PerformanceStressCorrosionCrackingCorrosionMechanismsSour GasTestingCustomized tests designed to meet clientspecifications enable Institute engineers toaddress the long- and short-term needs ofthe client and provide flexibility in testing.SwRI engineers can offer a broad-based viewof corrosion through long-term exposuretesting, materials selection and life predictionstudies, and failure evaluation.Electrochemical TestingThe Environmental Performance ofMaterials (EPM) Laboratory at SwRI hasthe latest electrochemical instrumentationcapable of monitoring materials performancein corrosive environments. SwRI’selectrochemical testing program capabilitiesinclude testing and evaluation of corrosionrates, galvanic corrosion, uniform corrosion,impedance and pitting. Using data generatedfrom these studies, SwRI scientists andengineers analyze corrosion mechanisms anddevelop innovative solutions to mitigate theeffects of corrosion in industrial situations.Sour Gas TestingThrough the Institute’s sour gas testing program,SwRI scientists and engineers providesolutions to the oil and gas industry’s downholeproduction issues that arise from stresscorrosion cracking. H 2 S / sour gas testing iscarried out in both gaseous and aqueousenvironments in a variety of configurationsD016994_6558High pressure high temperature (HPHT) testing can be performedto determine stress cracking and/or mass loss corrosioneffects under H 2 S, CO 2 or other gaseous environments.Testing can be performed up to 650 F and 20,000 psi.including static, slow strain rate, tensile, fatigue andcreep. SwRI offers an array of H 2 S and high-pressuretesting. In addition to H 2 S, the testing environmentmay also include CO 2 , CH 4 and/or N 2 .ASTM, NACE and Standardized TestingThe EPM Lab routinely performs ASTM, NACE andother standardized testing. In the lab’s atmosphericcorrosion testing program, routine tests include:■ GM9540P – accelerated corrosion test■ SAE J2334 – laboratory cyclic corrosion test■ ASTM B117 – salt fog testDE131985The testing andevaluation ofcorrosion rate,galvanic corrosion,uniform corrosion,impedance and pittingcorrosion are a fewexamples of theextensive testingcapabilities of SwRI’selectrochemicaltesting program.D014536_7369Stress cracking evaluations performed using C-ringconfiguration. Samples are immersed in a simulatedsolution and evaluated for cracking after testing todetermine the environmental response.
