cathodic protection

Soil stress and excessive operating temperatures can damage pipe coating and expose pipe to external corrosion. Water and corrosive contaminants in the product stream can cause internal corrosion damage. High operating stress levels combined with environments conducive for stress corrosion cracking can cause cracking failures.

Regular pipeline assessment is critical in order to mitigate these issues. Corrpro offers engineering assessment, data analysis and management for baseline assessment and reassessment programs.

Corrpro is a world-class leading provider of external corrosion direct assessment (ECDA) related engineering, surveys and data analysis, inspection and remediation. Our Pipeline Services Division includes numerous personnel with more than 20 years' experience in pipeline testing and integrity assessments. For more than 15 years, we have been one of the largest providers of these types of services in the United States.

Corrpro's ECDA services include: 

  • Pre-assessment
  • Indirect examination
    • CIS potential surveys
    • DCVG surveys
    • Electromagnetic surveys
    • ACVG surveys
  • ACCA surveys
    • Soil studies
    • Resistivity surveys
    • Depth of cover
    • Sub-meter GPS locating
  • Direct examination
    • Excavation and inspection
    • Coating evaluation
    • Corrosion measurements
    • MIC investigations
    • Pipe strength calculations
    • Root cause analysis
    • Corrosion rate estimates
  • Engineering critical assessment
    • Post assessment

Corrpro’s team of internal corrosion experts provide comprehensive solutions for internal pipeline integrity. These services cover initial corrosion assessment and testing, design and planning of mitigation programs and measurement of the efficacy of corrosion control efforts.

Starting with internal corrosion direct assessment (ICDA) to identify maximum risk locations, the control of internal corrosion in pipelines is optimized by one or more of the following activities:

  • Pipeline system evaluation and assessment
  • Engineering calculations
    • ICDA process optimization
    • Prediction of corrosivity
  • Laboratory analysis of gas, liquids and solids
  • Microbiologically influenced corrosion (MIC) testing, studies and evaluation
  • Corrosion monitoring
    • Coupons
    • Probes
    • NDT (non-destructive testing, in-line inspection, ultrasonic)
  • Cleaning pig programs
  • Application of inhibitors and bactericides

Stress corrosion cracking (SCC) is an integrity threat for many pipeline operators. Corrpro’s staff is experienced at direct assessment methodologies and in performing SCCDA requirements for both near-neutral-pH and high-pH SCC.


Corrpro is one of the nation's leading pipeline inspection companies providing pipeline integrity inspection services. Our Pipeline Services Division has managed in-line inspection projects for more than 25 years and has processed in-line inspection data for more than 12,000 miles of natural gas and hazardous liquid pipelines.

In-line inspection related services provided by Corrpro include:

  • Tool selection
    • Cleaning
    • Gauging
    • Deformation
