Environment and Cathodic Measurement

Buried pipelines are exposed to elements that can speed corrosion. Maintaining pipeline integrity requires studying the surrounding substrate and the pipeline to detect pending problems or deterioration. Environment and Cathodic Measurement tests use different means to evaluate soil composition and pipeline conditions to detect defects, corrosion, or other possible issues.

Different tests seek to measure or evaluate various aspects of the soil surrounding buried pipelines. While buried pipelines are relatively safe from vandalism or other impacts, they are susceptible to wear and tear from the soil and contaminants. Even the effects of heat and cold, moisture, and sub-surface movement impact buried pipelines and can cause failures over time.

Circle B Non-Destructive Examination specializes in various forms of environment and cathodic measurement and many other forms of pipeline integrity management to keep your pipeline systems operating safely and efficiently. Contact us today to learn more.

  • Pipe to Soil Potential Testing
    Pipe-to-soil potential refers to measuring and assessing the electrical potential difference between a buried pipeline and the surrounding soil. This measurement is crucial in corrosion control for pipelines, particularly in cathodic protection systems. By monitoring and maintaining the appropriate pipe-to-soil potential, operators can prevent or mitigate corrosion, ensuring the longevity and safety of the pipeline.

  • Soil pH Testing
    Soil pH testing measures the acidity or alkalinity of the soil surrounding a pipeline. Monitoring soil pH is essential for assessing the corrosiveness of the environment in which a pipeline is buried. An appropriate soil pH level is crucial for corrosion control, as overly acidic or alkaline soils can accelerate the corrosion of pipelines, potentially leading to structural damage and safety risks.

  • Soil Resistivity Testing
    Soil resistivity testing measures the soil’s ability to resist the flow of electrical current. It is a critical parameter for assessing the corrosiveness of the environment around buried pipelines. Low soil resistivity can indicate high moisture content and increased corrosive potential, making it essential for designing effective cathodic protection systems to prevent corrosion and ensure the long-term integrity of pipelines.

  • Microbial Induced Corrosion Sampling & Testing
    Microbial-induced corrosion (MIC) sampling and testing collects and analyzes samples from pipelines to detect and assess the presence of corrosion-causing microorganisms. MIC occurs when specific bacteria, archaea, or other microorganisms interact with the pipeline’s metal surface, leading to corrosion. Circle B NDE specialists use these samples to develop targeted mitigation strategies to prevent further damage and ensure the pipeline’s integrity.

Circle B NDE specialists perform environment and cathodic measurement testing to analyze the substrate surrounding a buried pipeline to determine the level of corrosive properties. We can then help you design prevention strategies to make your pipeline last longer and prevent future problems.
