Pipeline Cathodic Protection Test Inspection Checklist [FREE PDF]

Cathodic protection (CP) systems are mandated under 49 CFR Part 192 and API RP 1160 to prevent external corrosion on buried or submerged pipelines. Regular test point surveys and rectifier output checks are legally required at intervals not exceeding 12 months for most pipeline segments. This checklist guides Pipeline Inspectors through a structured evaluation of CP system performance, ensuring compliance with federal corrosion control requirements and documented evidence for regulatory audits.

  • Industry: Pipeline Operations
  • Frequency: Annually
  • Estimated Time: 60-90 minutes
  • Role: Pipeline Inspector
  • Total Items: 34
  • Compliance: API RP 1160 - Pipeline Integrity Management, 49 CFR Part 192 Subpart I - Corrosion Control, 49 CFR Part 195.571 - Cathodic Protection Criteria, NACE SP0169 - Control of External Corrosion on Underground Pipelines, API 1104 - Welding of Pipelines and Related Facilities

Rectifier Unit Inspection

Verify rectifier output settings, physical condition, and operational status in accordance with corrosion control requirements.

  • Is the rectifier unit energized and operating at the required output voltage?
  • Is the rectifier output current within the design specification range (amps)?
  • Is the rectifier output voltage within the design specification range (volts)?
  • Is the rectifier enclosure free from physical damage, corrosion, and unauthorized access?
  • Is the last rectifier inspection date recorded and within the required 60-day check interval?

Test Point Pipe-to-Soil Potential Surveys

Measure and record pipe-to-soil potentials at designated test points to confirm cathodic protection criteria are met.

  • Is the pipe-to-soil potential at this test point at or more negative than -850 mV (CSE)?
  • What is the measured ON potential at this test point (mV CSE)?
  • What is the measured OFF (instant-off) potential at this test point (mV CSE)?
  • Is the reference electrode (half-cell) calibrated and in proper working condition?
  • Are test point lead wires intact, properly connected, and free from damage?
  • Is a photograph of the test point meter reading captured for record-keeping?

Anode Bed & Ground Bed Assessment

Evaluate the condition and output of sacrificial anode beds and impressed current ground beds.

  • Are all anode bed lead connections secure and free from corrosion at the junction box?
  • Is the ground bed resistance within acceptable design limits (ohms)?
  • Is the anode bed area free from surface disturbance, excavation, or third-party intrusion?
  • Are individual anode outputs within expected current distribution range?
  • Is there any evidence of anode consumption beyond 80% depletion requiring replacement?

Electrical Interference & Stray Current Assessment

Identify and document sources of electrical interference that may compromise cathodic protection effectiveness.

  • Is there evidence of stray current interference from adjacent utilities or DC sources?
  • Have potential fluctuations greater than ±50 mV been observed at any test point?
  • Are all casings electrically isolated from the carrier pipe at casing test points?
  • Are isolation flanges and joints tested and confirmed to be electrically effective?
  • Have interference mitigation bonds been tested and confirmed to be operating within design parameters?

Pipeline Coating Condition Assessment

Evaluate the integrity of external pipeline coatings as part of the overall corrosion prevention system.

  • Is there any above-ground evidence of coating damage, disbondment, or cathodic shielding at exposed segments?
  • Has a DCVG or CIPS survey been conducted on this segment within the last assessment cycle?
  • Are all aboveground pipe-to-air transition points coated and wrapped per specification?
  • Has any field-applied coating repair been documented and reported within this inspection period?

Documentation & Records Verification

Confirm that all CP test data and system records meet regulatory retention and reporting requirements.

  • Are all prior CP test records for this segment available and retained for a minimum of 5 years?
  • Has this inspection been logged in the operator's integrity management system?
  • Are any corrective actions from the previous CP inspection verified as completed and closed?
  • Has the CP survey data been submitted to the relevant state pipeline safety authority if required?
  • Are as-built drawings for the CP system current and accurately reflecting any modifications made this period?

Deficiency Identification & Remediation Planning

Document identified CP deficiencies and establish corrective action timelines.

  • Were any CP protection criteria failures (below -850 mV CSE) identified during this survey?
  • Has a corrective action report been initiated for all identified CP deficiencies?
  • Have priority remediation segments been communicated to the corrosion control engineer?
  • Are additional inspection notes or observations documented in the remarks section?
