VCI INSTALLATION CONSIDERATIONS AT MILITARY FACILITIES

摘要

What does it take to prepare a structure for vapor corrosion inhibitor (VCI) installation? What tasks are required to ensure that an effective amount of inhibitor is being maintained? What are some of the methods utilized to prolong the effective life of VCI's? With new pipelines/aboveground storage tanks being built and existing pipelines/aboveground storage tanks aging, cased crossings and tank bottoms are ideal applications for VCI's. Military facilities are beginning to utilize these products. Safety, coordination, troubleshooting, various testing methods and construction practices are some of major parts associated with proper VCI installation. As corrosion engineers we must work in all of these areas to ensure that VCI's can be utilized to their full capacity. This paper discusses the many concerns related to VCI installation for cased crossing and aboveground storage tank bottoms at military facilities. Including safety, testing, documentation and lessons learned. Also addressed are NEC requirements where applicable. The topics discussed are practical and the lessons learned are first-hand accounts. The purpose of this paper is to share what has been learned and some of the company policies that have been taken from many years of pipeline and tank farm operation at military facilities.
