Corrosion Inspection and Testing
Corrosion Hazards Identification
1. Systematic Inspection for Corrosion Risks in Process Equipment & Pipings
For potential corrosion hazards in refining and chemical enterprises, this specialized technology employs corrosion loop analysis to identify key areas requiring corrosion monitoring. It then uses techniques such as pulsed eddy current and ultrasonic thickness measurement for on-site verification and troubleshooting.
● Risk identification based on corrosion circuit analysis, enabling prediction of areas with severe corrosion and critical pipelines.
● Conduct troubleshooting by combining multiple advanced detection methods, including pulsed eddy current and magnetic memory technologies.
● Some sections may not require removal of thermal insulation for inspection; after identifying potential hazards, proceed with removing the insulation for re-inspection.
● Conduct regular tracking and monitoring to oversee the implementation of corrective actions and achieve closed-loop management of corrosion risks.

2. Identification of External Corrosion Hazards (including Corrosion Under Insulation Layers)
External corrosion hazards (including corrosion under insulation) are commonly found in facilities with longer service lives and in coastal areas. Therefore, proactively conducting inspections to identify external corrosion hazards is a necessary measure for ensuring the intrinsic safety of these facilities.
1) Process for Identifying and Addressing External Corrosion Hazards
2) On-site inspection methods for external corrosion detection
● Macroscopic observation
● Ultrasonic thickness measurement
● Infrared thermal imaging
● Insulated Pulse Eddy Current Scanning
● Low-frequency guided wave inspection, etc.
A certain enterprise has been conducting inspections for external corrosion hazards for five consecutive years. As the operating time of the equipment has increased, the number of corrosion hazards has gradually risen. However, thanks to the continuous inspection efforts, the detection rate of these hazards first rose steadily, reached a peak, and then began to decline gradually—indicating that as the inspection work has deepened, potential hazards have been progressively reduced.
3. Other special inspections
● Colon and dead-end area inspection
● Safety valve pipeline inspection
● Inspection of water and agent injection points
● Special inspection of pressure gauge lead wires, etc.
