... a constant load scenario. The objective of this paper is to present a new experimental method using a compact Single Edge Notched Tension (SENT) specimen for assessing the SIF threshold for crack growth initiation. The test method provides the same framework as Method A of the NACE TM0177 standard...

... Abstract The use of 0.05 psi H 2 S partial pressure as the threshold determining when sulfide stress cracking (SSC) resistant materials are needed was codified in NACE MR 0175 (1975) nearly a half century ago and has served the industry well since implementation. The origins of this pressure...

... or SMS that are triggered if a threshold has been breached on a pre-configured limit. Alarms have been a wonderful invention for the industry, ensuring that the right people are notified as soon as data, indicative of a potential problem, exists. Alarms have revolutionized how pipeline operators monitor...

... approaches that avoid equipment being exposed to stresses or strains exceeding the nominal thresholds for HISC. This approach is captured by DNV Recommended Practice F112: 2008 (DNV RP F112: 2008). Full scale test validation of this approach is limited. A comprehensive test program is described quantifying...

... ABSTRACT The potential of passive steel embedded in concrete is a key parameter on the value of the chloride corrosion threshold. The phenomenon of a potential-dependent chloride threshold (PDT) along with the corrosion macrocell coupling between active and passive steel assembly components...

... ABSTRACT Previous work has shown that chloride corrosion threshold increases when steel bar potentials are more cathodic than -200±50 mV (SCE). When corrosion starts at a given location, the steel of the adjacent regions remains in its passive state; therefore corrosion initiation is delayed...
