Pipeline Corrosion Inspection Checklist

Coating

Are whip checks installed on hoses?

Is protection in place to prevent blast media from entering valves, pipe, fittings and appurtenances

Is the coating on steel pipe sufficiently ductile to resist cracking?

Are all materials handled and stored as per Manufacturer specifications?

Are materials not expired per Manufacturer expiry date(s)?

Are all containers for coating material in good condition and not damaged in any way?

Are all required x-rays completed before applying protective coatings?

Are all jeep equipment settings appropriate for different thicknesses of coating?

Are all coating defects marked, repaired, and pipe sections re-jeeped before lowering-in pipe?

Is the general housekeeping of coating related debris (e.g., gloves, brushes, rollers, containers, overspray) done?

Cathodic Protection

Have key issues been identified, detailed, and addressed?

Are considerations for locating cathodic protection test stations integrated (such as the use of existing facilities (e.g., valve or scraper trap locations) and ease of accessibility (e.g., valve or scraper trap locations)?

Is there sufficient communication to facilitate that requirements of the crossing agreement are met in a safe and efficient manner?

Are cathodic test stations near existing roads for ease of accessibility during subsequent periodic testing in locations specified on project drawings?

Are existing rectifiers to be shut down in areas where existing pipe maintenance programs are underway?

Are test leads backfilled carefully to avoid breaking wire-to-pipe connections and burying the lead wires before connections to the junction boxes are completed?

Are both ends of the conduit leading up to the junction box reamed out to remove any burrs that may
cause a short in test lead wires?

Are test leads tested electrically after backfill to confirm that wire-to-pipe connections have not been broken?

Are test stations installed as close to pipeline crossings as possible?

Are CP readings are taken by pipe-to-soil reading if the coating has been damaged?
