Cathodic Protection Annual Pipe-to-Soil Survey

Annual inspection template for recording pipe-to-soil potential readings on steel gas and water mains and verifying cathodic protection performance against the -0.85 V CSE criterion per NACE SP0169, with corrective action tracking for deficiencies and non-conformances.

Inspection Details

• Survey date and time recorded
• Inspector name and company recorded
• Pipeline asset identified
  Include pipeline name, segment, stationing, or test station ID.
• Asset type selected
• Survey method documented
• Weather and soil conditions noted
• Reference standard noted
  Verify readings against the -0.85 V CSE criterion used for cathodic protection evaluation per NACE SP0169.

Reference Electrode and Test Setup

• Reference electrode type confirmed
• Reference electrode condition acceptable
  Electrode is clean, intact, and suitable for field use.
• Lead connections secure and free of damage
• Test equipment calibration current
  Record the most recent calibration or verification date for the voltmeter or data logger.
• Measurement setup free of obvious interference
  Confirm no obvious electrical interference, poor contact, or unsafe access conditions affected the reading.

Pipe-to-Soil Potential Readings

• Measurement point 1 location
  Identify the test station, milepost, valve box, or accessible point.
• Measurement point 1 pipe-to-soil potential
  Enter the stabilized pipe-to-soil potential reading referenced to CSE.
• Measurement point 1 meets -0.85 V CSE criterion
• Measurement point 2 location
  Use additional points as needed for the survey route.
• Measurement point 2 pipe-to-soil potential
• Measurement point 2 meets -0.85 V CSE criterion
• Additional readings documented
  Record any additional pipe-to-soil readings, including location, value, and notable conditions.

Deficiencies and Corrective Actions

• Deficiencies identified
• Corrective action required
• Corrective action details
  Describe repairs, retest requirements, or escalation to corrosion engineering or the AHJ.
• Follow-up due date
  Enter the target date/time for retest or corrective action completion.

Sign-Off

• Survey record reviewed for completeness
• Inspector signature
• Supervisor or corrosion engineer review
  Use when internal procedure requires technical review or approval.
