Atmospheric Corrosion Inspection - Gas Piping

Inspection template for exposed gas piping, risers, and meter sets to identify atmospheric corrosion, document deficiencies, and track remediation actions in accordance with 49 CFR 192.481 and applicable OSHA/NFPA requirements.

Inspection Details

• Inspection date and time recorded
• Facility / site identification recorded
• Inspector name and qualification documented
• Inspection scope includes exposed gas piping, risers, and meter sets
• Weather / environmental conditions noted

System Identification and Exposure Conditions

• Exposed piping material and coating type identified
• Piping, risers, and meter sets are visibly accessible for inspection
• Signs of moisture retention, standing water, or poor drainage present
• Evidence of contact with soil, concrete, insulation, or other corrosive surfaces
• Ventilation and air circulation around exposed components are adequate

Atmospheric Corrosion Condition Assessment

• No visible atmospheric corrosion on exposed piping surfaces
• No coating blistering, cracking, peeling, or disbondment observed
• No active rust scale, pitting, or measurable metal loss observed
• Fasteners, clamps, supports, and brackets are free of corrosion that affects integrity
• Meter set, regulator, and associated appurtenances show no corrosion-related leakage indicators

Protective Measures and Remediation

• Protective coating or wrap is intact where required
• Corrosion inhibitor, sealant, or other preventive measure is present where specified by procedure
• Deficiencies identified and documented with location-specific detail
• Corrective action assigned with responsible party and due date
• Remediation status updated for any prior corrosion findings

Sign-Off and Follow-Up

• Immediate hazard or leak condition present
• Escalated to supervisor / operations / AHJ as required
• Inspector comments and summary of findings
• Inspector signature
