交流電圧勾配調査（ACVG）

By taking progressive measurements along the pipeline, our engineers can detect potential coatings defects for later excavation and repair. Additional benefits of conducting ACVG surveys over theジクロロメタンmethod include defect size estimation. Once the data is collected, it is analyzed by professional engineers who hold NACE certifications. Let our Cathodic Protection Specialists (CP4) help you through the process of acquiring and analyzing the data for a crystal clear understanding of the underlying causes of any vulnerabilities and how to address them in the most cost-effective manner.
