...TEST METHODS Visual Inspection The first step when determining whether or not electrical isolation is adequate for a DC powered rail transit system should always be a visual inspection of the section of interest. The section of interest can range from a single rail segment 100 feet (30.48 meters...

... exposure, the lack of standardized test, as well as the presence of impurities in the CO₂ stream can modify (expand) the type of corrosive species to be considered in comparison with typical environments in oil & gas production. In this paper, we summarized the efforts to understand...

...Where: V = test voltage and T = coating thickness (mils) All holidays, pinholes, discontinuities, and other coating defects such as blisters, voids, cracks, and thin spots were identified and repaired with approved procedure before pull through. After pull through, the first two (2) lengths of pipe...

... and the ability of composites to repair bends and restore the structural integrity of the facility piping will be discussed. Testing and currently in use examples will be used to show the benefit of composites in facility integrity systems, including the ability to keep the facility safe while avoiding a costly...

... materials selection and design process, there exists a need for accelerated testing as means to screen candidate materials on key performance metrics. Arguably, one key metric to maximize for hydrogen barrier coating selection is the so-called permeability reduction factor (PRF), which is the ratio...

... if the water salinity is 1% at heating temperature of 50°C for one hour. The higher the salinity of the water, the less extraction yield was observed. chemical inhibitor oil and gas production testing INTRODUCTION Sample preparation is the fundamental step of any analytical procedure, which involves...

... and effectiveness of these techniques. post-tension (PT) evaluation drying tendon cable corrosion testing tension magnetic INTRODUCTION Unbonded post-tensioned reinforcement in concrete structures has been used for many years in elevated slabs (parking garages and residential or commercial buildings...

...Abstract In order to successfully select an effective corrosion inhibitor, it is important to make a thorough assessment during a chemical qualification process. To efficiently make a selection, screening tests are generally performed prior to more complex field representative tests...

... reports that utilize contact angle measurements rely on principle of the hydrophobic tail of the VCI contributes to the overall surface tension change and pronounced water droplet (larger contact angle). The test panels that were used for this experiment were AISI 1010 steel ¹⁷ with dull...

... and/or technician will be called upon to direct welding operations in accordance with the project specifications. Abstract This paper will present field verified methods for corrosion engineers and/or technicians to accurately inspect and log structure configuration, field conditions and perform field tests...

... in an effort to draw some parallels, but again, that method is not totally definitive. One way to definitively prove whether capacitive effects will exist for an AC mitigation system is to install the system and conduct direct testing. A test device is currently available that has a capacitor to simulate...
