Although we consider every project to be an individual one with unique characteristics, we have provided a sample list of projects we often come across so you can garner a better understanding of a typical project for Russell Corrosion Consultants.

CORROSION EVALUATION/PIPE CONDITION ASSESSMENT: A "typical" corrosion evaluation includes a comprehensive evaluation of an asset in order to determine how corrosive the environment is, and what corrosion control methods can be selected and ultimately designed and implemented. The purpose of the corrosion evaluation is to determine the overall pipe condition, the extent of metal loss due to corrosion, and the anticipated remaining life expectancy of the pipe. As a result of the collection and analyses of specific data, high risk areas will be identified and sections can be prioritized for direct examinations with respect to the need for rehabilitation or replacement based on their condition and probability of failure.
CORROSION CONTROL DESIGNS: A "typical" corrosion design would include the preparation of final design drawings and specifications as well as cost estimates for the installation of the recommended corrosion protection services. Corrosion protection services generally consist of preparing design documents for the installation of recommended protection methods (i.e. cathodic protection) as well as calculations, contract drawings, specifications, O&M manuals, and construction estimates.
TRANSIT SERVICES: A "typical" transit system project would include a design for transit corrosion control systems. The design of the corrosion control system starts with implementing the best practices from RCC past experience with corrosion control designs for transit systems. RCC will typically perform the following tasks in assessing corrosion control needs for transit systems:
- Conduct baseline stray current surveys
- Estimate stray current during transit system design
- Computer modeling of stray current levels under various configurations
- Perform track to earth resistance testing
- Perform track voltage testing
- Perform stray current testing for utility structures
- Perform stray current testing for elevator structures
Once all testing is performed, Russell Corrosion will tabulate the data. By assessing this data and the associated risk factors, the extent of corrosion control requirements will be determined. Typically we will then provide detailed corrosion control designs for the client.
PIPELINE FAILURE: Russell Corrosion Consultants, Inc. (RCC) often gets called to perform a failure analysis on a failed pipeline. An on-site inspection will be performed to obtain soil samples, physical evaluation of the failed pipe section and photo documentation will be secured. RCC can determine likely causes of the failure. Next steps typically include additional soil sampling, obtaining a pipe coupon for analysis, and other corrosion evaluation techniques. Once all analysis is performed RCC will identify other areas of the pipeline which have the potential for failure due to corrosion. Russell Corrosion can also provide the client with detailed designs for corrosion control services if they desire. In response to the survey results, the client can undertake a corrosion prevention program to prevent major failures in the future, thus saving its citizens countless tax dollars.
TANK STRUCTURES: A typical tank structure project will entail RCC being deployed to perform either a survey of already cathodically protected structures or to evaluate and design cathodic protection for new tank structures. In order to perform a proper monitoring and survey on an existing cathodic protection system RCC will assess current systems. Data would be obtained by synchronously interrupting the applicable rectifiers providing cathodic protection to the tank bottoms and associated piping. RCC will then verify above ground connections to the tanks. We will record operating data for applicable rectifiers, and we will provide data analysis and conclusions as to the effectiveness of the existing cathodic protection systems and identify any areas of concern. RCC will then provide a summary report of our findings to the client and we will provide cost estimates for any additional evaluations or repairs that may be needed.
GAS PIPELINE CORROSION SURVEY: A "typical" gas pipeline corrosion survey will consist of RCC conducting a survey of the test stations along the pipeline's right-of-way. "On" and "Instant Off" pipe-to-soil potentials will be obtained utilizing a high impedance voltmeter to verify effectiveness of test wires and to verify levels of cathodic protection. Data will be obtained by synchronously interrupting the applicable rectifiers providing cathodic protection to the pipeline. RCC will then verify the effective electrical isolation at the beginning and end of the pipeline. We will obtain "On" and "Instant Off" pipe-to-soil potentials on accessible casing vents to verify effective isolation. We will then measure bond current, record operating data for applicable pipeline rectifiers, and provide data analysis and conclusions as to the effectiveness of the existing cathodic protection system and identify any areas of concern to our client.
SUMMARY: The above samples are only a small selection of "typical" projects we perform at Russell Corrosion Consultants, Inc. We may have seen it before, but it is imperative that each one of our clients know we VALUE their trust in us, and we treat each of their needs as our singular driving focus. Whether it is a big job or small undertaking, RCC is dedicated to helping our clients achieve their goals. We will provide every client the full attention they deserve.
