Results confirmed the effectiveness of VCI products in various water chemistries including fresh and salt water. Average corrosion rate dropped from ~10 mpy...

... levels of vapor corrosion inhibitors (VCIs), and combinations of VCIs, CP, and possibly biocides. The objective of this work was to develop, test, and validate an ultrasonic testing (UT) resonance probe and a corrosion monitoring cell to quickly evaluate the effectiveness of corrosion control measures...

... the effectiveness of conventional monitoring and cathodic protection techniques. This paper summarizes the results of research sponsored by the Pipeline Research Council International. Field testing was conducted at a long crossing installed in rock where an array of monitoring and cathodic protection equipment...

... ABSTRACT In this work, a case study for the Life Cycle Costing (LCC) analysis to quantify and compare different corrosion mitigation methods based on their effectiveness and make an informed decision on the strategies to minimize the costs due to corrosion is presented. The LCC for corrosion...

... soil side ER corrosion probes can be used to determine part of the external corrosion threat when CP system effectiveness is inadequate. However, soil side ER corrosion probes typically require a 12-month measurement time frame to establish representative corrosion growth rates. In this review...

... ABSTRACT The protection effectiveness of commercially available vapor corrosion inhibitors powders with different particle size was evaluated. Conventional powder size of and nano-particle powder inhibiting effectiveness was compared using the vapor-inhibiting ability (VIA) NACE TM 208...

... in a full-scale Coke Oven Gas (COG) desulfurization process in which the corrosion rate changed with time. 1 The underlying causes of corrosion and the effectiveness of possible countermeasures were evaluated using corrosion simulation software. As a result of progressive improvements, the severe corrosion...

... ABSTRACT This work evaluated the effectiveness of the dewatering process after hydrotesting and examined the internal corrosion threat posed by residual water trapped in crevices and water pushed into a dead leg. A “time to dry” calculation for both cases was conducted based on pipeline...

... to employees and the environment. UV treatment provides an alternative to biocide, but the effectiveness of UV treatment compared to biocide treatment has to be proven before implementation in a specific system. The effectiveness of biocide treatment is often measured using culturing methods, however, one...

As a result, it is important to understand how the NRB and SRB population profile controls the effectiveness of nitrate on SRB growth, sulfide levels, and corrosion. In laboratory studies, the impact of NRB (including...
