스마트 정밀안전진단, 전기방식설계, 배관관리장비, 통합관리형 IoT 모니터링 시스템
ECDA (External Corrosion Direct Assessment)
￭ 방식(CP) 시스템과 피복 품질에 대한 검사
￭ 모재손상(부식진행) 확률이 높은 지점을 직접 굴착 검사
￭ 부식원인에 대한 정보 (root cause) 제공
매설구조물 부식진단 I
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)
매설구조물 부식진단 II
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
피복손상탐측 (DCVG)
매설구조물 부식진단 방식시공 III
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
