...This paper presents a comprehensive summary of soil data from a single provider, ISRIC. This research’s grander plan seeks to model the relationship between soil parameters and ILI-based corrosion growth rates from a North American Operator. The ultimate objective is to incorporate this data...

...In the recent years, multiple studies concluded that the increase in pH, promoted by the generation of OH^- at the steel surface as a consequence of the protection current, is fundamental for achieving corrosion protection of the steel in soil, namely passivation ^{7 – 9 , 13 , 14}...

... such as aqueous solution as well as soil in order to evaluate the integrity of the members of facilities. As a nondestructive monitoring method, CIPE (Current Interrupted Polarizing Extrapolation) method was developed. By the CIPE method the corrosion rate is calculated by the Tafel equation obtained from...

...Abstract This paper focuses on a preliminary study of the use of halophytes to manage the characteristics of soil. Halophytes, such as switchgrass and salt bush, are capable of altering the characteristics of the soil over time, possibly reducing conductivity and corrosivity. These types of plants...

... in Figure 7 . Abstract Cathodic polarization behaviour was examined for UNS K02600 carbon steel coupons in thirty (30) soil samples collected throughout central and southern Alberta, Canada. The polarization of coupons was studied as it relates to current density and soil properties. Polarization data...

... plots are identified as SW and SWPL . The SWPL is also located beneath the same set of P ower L ines. In the spring of 2018, and again in 2019, soil and plant samples were taken from the four plots located at the test site. The depths of the soil samples were taken in one foot increments, down...

...Pipeline corrosion growth rates (CGR) are also dependent on a variety of exogenous factors, including pipeline conditions such as coatings or construction, environmental conditions such as pollution, rainfall, and soil conditions such as salinity, pH, electrical conductivity, and seasonal variation...

... the estimations in this work as our primary dependent variable. Abstract Estimating corrosion growth rate for underground pipelines is a non-linear, multivariate problem. There are many potential confounding variables such as soil parameters, cathodic protection, AC/DC interference, seasonal / climate conditions...

...Differential Settlement Differential settlement is a result of the uneven deformation of the supporting foundation soil. ^{30 , 31} The factors affecting structural settlement include the type of foundation soil (e.g., clayey soil, sandy soil) and its physical properties, thickness...

.... pipeline natural environment atmosphere soil water oil gas corrosion fire explosion contamination diagnostic INTRODUCTION Worldwide experience shows that existing corrosion protection systems (coatings, cathodic protection systems (CPS), and their combination) can guarantee an expected...

...Abstract AC corrosion is dependent on both AC and DC current densities, but only little is known about the effect of the chemical environment. In this paper, laboratory soil-box experiments are made for a better understanding of the effect of specific chemical constituents in soil on corrosion...

...INTRODUCTION The use of metallic coupons to quantify the cathodic protection (CP) of buried pipelines is a common practice, although the field measurements results are often questionable and sometimes not reliable. Considering the complexity and expected high resistivity of soils, the design...

.... In addition, the products for metal working application provide corrosion protection to the cleaned metal parts. Three products were evaluated: a soil bio-remediator, and two degreasers. The test results show that the soil remediator had a 60% reduction of hydrocarbons in contaminated soil vs an untreated...

...Abstract This paper investigates the effect of over /under protection of impressed current cathodic protection (ICCP) system that applied on Dupplex Stainless Steel (DSS) buried in soil environment. Stepped constant load testing (SCLT) at different ICCP potentials and temperature has been carried...

...From the initial test, a number of electrodes that showed good results were chosen to be tested in six simulated soil environments. As will be discussed in the next section, the electrodes included for the soil environments included the Ag/AgCl, Cu/CuSO₄, tungsten, and the SCE electrodes...

...Abstract Corrosion of soil side bottoms is unpredictable and can be up to 5 mm/year. The soil side bottom cannot be protected while the tank is in service. The well-known cathodic protection system is not efficient enough. This paper presents case studies of soil side bottom corrosion protection...

...Dust Corrosion Inhibitor Lactobionic Acid Magnesium Chloride Calcium Chloride Soil INTRODUCTION Abstract A wide variety of materials has typically been available to prevent the production of dust from unpaved surfaces. Dust control agents mixed with fine soil can remain on metal surfaces...

...Abstract Galvanized steel is generally used in mechanically stabilized walls to reinforce the soil due to its high corrosion resistance compared to carbon steel and also its cost effectiveness compared to stainless steel. With galvanized steel reinforcement, steel is protected against corrosion...
