... on the critical stress intensity factor for sulfide stress cracking (K ISSC ). A common Cr-Mo high strength OCTG steel alloyed with three different Nb contents ranging from 300 to 1000 ppm is used. It was found that Nb addition allows the use of higher strength material without compromising the resistance...

... of the flaw tip. Consequently, material cracking resistance is affected by the subsurface hydrogen uptake conditions. The hydrogen concentration variation inside the metal results in significant complexity when attempting the determination of cracking resistance in an environment as a function of hydrogen...

...), and Constant Load Verification (CLV). A new Ni-Cr-Mo-Fe alloy UNS N08830 alloy was recently evaluated for resistance to Hydrogen Induced Stress Cracking (HISC), simulating conditions arising during cathodic protection in a subsea environment. The unique set of test methods and conditions included SSRT...

... ABSTRACT The use of ASTM 4060 Tabor Abrasor Testing has long been the standard for comparing the wear characteristics of different coating systems. This has been done with standard impregnated rubber disks to allow for the industry to look across companies and compare the abrasion resistance...

Weldability of this material has been studied with the support...

... hardness. Several SOHIC resistance test methods have been reported, but none of the test methods is currently standardized. The newly developed “twist and bend” test is currently under standardization in NACE TG 536. Within this work, SOHIC resistance tests using the “twist and bend” test method were...

... ABSTRACT Duplex stainless steels were introduced and have been actively developed by European companies since 1935. Their properties make them very attractive compared to equivalent austenitic grades: higher resistance to stress corrosion cracking, higher mechanical strength and lower alloy...

... ABSTRACT Assessing and mitigating AC corrosion on pipelines with multiple coatings presents some unique challenges especially when there are significant coating resistance changes between them. Gas pipelines are constantly being upgraded due to class locations/relocations which result...

... ABSTRACT Corrosion resistant alloys (CRAs) have been used in exploration and production fields which contain high pressure, high temperature and significant amounts of hydrogen sulfide, carbon dioxide and chloride ions. As exploration for High-Pressure High-Temperature (HPHT) hydrocarbon...
