Pipeline integrity assessment, corrosion diagnosis and failure analysis system, safety IoT Monitoring system
ECDA (External Corrosion Direct Assessment)
■ Inspection CP system and coating
■ Structure Failure Direct Exam.
■ Analysis of corrosion root cause
Underground Pipeline Integrity Inspection 1
CP management and routine surveys
■ On/OFF potential measurement
■ Soil resistivity measurement
■ Pipeline locating survey
■ Isolation test
■ Soundness of CP facilities (TB and rectifier, etc)
Underground Pipeline Integrity Inspection 2
CP in-depth surveys
■ CIPS (Close Interval Potential Survey)t
■ Coating Defect Survey (DCVG)t
■ Static (dynamic) interference survey t
■ Temporary ICCP tests for CP retrofit
Damaged Coating Detection
Underground Pipeline Integrity Inspection 3
ECDA (External Corrosion Direct Assessment)
■ Based on NACE RP0502-2002
■ Inspect the soundness of CP system and coating quality, basically.
■ Direct (excavation) inspection of points having a high probability of corrosion
■ Provision of root cause for corrosion
