...Abstract Carbon steel elements for motor engine assembly are produced in different companies typically settled far from the assembly plant. As corrosion must be avoided, condition of transportation are of paramount importance. VCIs are used in the packaging, applied of the polymer sheet used...

...Abstract An especially noteworthy and important analysis will be provided on the real-time field performance of stand-alone vapor corrosion inhibitor (VCI) systems in comparison to cathodic protection (CP) systems on aboveground storage tank (AST) floors. API 653 floor inspection data...

...Testing was performed in deionized water, with varying amounts of the corrosion inhibitor identified above from the VCI oil additive in solution. The solution was held in a cylindrical glass cell with a 5” height and 2” diameter. 200 g of each solution was used in each test cell to ensure full...

...Abstract This paper presents new applications of Volatile Corrosion Inhibitors (VCI) inside new and/or existing out-of-service pipelines. The system utilizes a combination of soluble and volatile corrosion inhibitors that are directly applied into the pipeline. In some cases, the decrease...

... near the critical weld between shell plates and chime plates. Volatile Corrosion Inhibitors (VCIs) have been implemented to reduce corrosion in this area and their effectiveness is presented in this paper. Direct Ultrasonic Thickness (UT) gauge inspection data and weight loss coupon data together...

... confirmed that corrosion control can be achieved in these tight spaces using volatile corrosion inhibitors (VCIs), which are a special class of corrosion inhibitors that have been gaining industry acceptance as a means to provide corrosion protection. The inhibitor will volatilize, migrate to the structure...

... to be effectively delivered to the tank bottom surface. Available research and fieldwork have shown that volatile corrosion inhibitors (VCIs) used independently or in combination with CP can be applied to protect the aboveground storage tanks (ASTs) bottoms from external corrosion. Protection occurs when VCI...

... are supported by combining Cathodic Protection (CP) and Inline Inspections (ILI) results within a structured, multi-criteria decision making matrix to create an enterprise listing for the casing management program. casings cased pipeline volatile corrosion inhibitor VCI corrosion management INTRODUCTION...

... water-based electrolytes, and in vapor/electrolyte inter phase. Simple preparations of these bio-based aromatic acids demonstrated that some of these materials possess ability of vapor phase corrosion inhibition (VCI). Some preparations of the bio-based acids showed potential as additive for mild steel...

...Abstract Benzotriazole and triazole compounds are well-known copper corrosion inhibitors. Also benzotriazole is used as Vapor Corrosion Inhibitor (VCIs) for copper. Sometimes copper is used together with iron and other metals within the same part or structure. To protect mixed metal components...

... and application of volatile corrosion inhibitor (VCI) chemistry to consider a new corrosion mitigation solution. This effort resulted in the development of a unique product designed to fill the annular space of a casing with a gelatinous product that proactively controls carrier pipe corrosion and prevents...

VCI SCC Critical pitting temperature steam turbine Volatile corrosion inhibitors physisorption brass and copper alloys INTRODUCTION Corrosion inhibition of the steam turbine rotor materials in power plants was investigated. It was successfully demonstrated for A470 (class 2 to 7...

... on this tank. Figure 3 identifies the different degrees of corrosion from the tank floor inspection report. The inspection results coupled with the existence of the grout under the floor plates caused the project to be revised. The scope of work was modified to include application of VCI chemistry under all...

...The addition of VCI properties to PE packaging films and bags makes them capable of largely overcoming the effects of water vapor in combination with most contaminants on the metal parts to be protected. However, diffusion into a sealed package may become a consideration when the external...

... This paper provides technical perspective on existing and planned NACE standards for test methods of rapid qualitative evaluation of the presence of vapor-inhibiting ability (VIA) of VCI materials. Several years work of a NACE Task Group resulted in recently published standard TM0208-2008 ¹...

...Abstract Volatile corrosion inhibitors (VCIs) compose a class of chemical compounds that have a suitable vapor pressure with which to diffuse throughout an enclosed volume, adsorb onto any exposed metallic surface within the volume, and inhibit corrosion in the adsorbed state. It has been...

...VCI Multielectrode array sensor steel INTRODUCTION Volatile Corrosion Inhibitors (VCI) have been in use for several decades, particularly in the packaging and electronics industry. These compounds typically function as supplementary corrosion prevention methodologies (similar to desiccants...

...The military sector lags the industrial sector in replacing legacy methods, such as oil coatings, desiccants and barrier packaging, with VCI materials. This paper offers three cases of cost analyses that were developed for decisions by companies that changed to VCI packaging for protecting ocean...
