With efficient execution developed over decades, inspections are carried out to support: 
• Early detection of corrosion and wall los 
• Inspection of inaccessible or insulated pipelines 
• Reduced inspection scope and cost 
• Targeted follow-up inspection planning

Equipment, Techniques & Detection Capabilities 

LRUT is a screening tool—not a replacement for UT. 

Operators typically use LRUT when: 
• They cannot access the full pipeline  
• They need to inspect long distances quickly  
• They want to reduce excavation or insulation removal  

LRUT identifies areas of concern along the pipeline. 

Follow-up inspection is then carried out using UTM (ultrasonic thickness measurement) to: 
• Quantify wall thickness  
• Confirm defect severity  
• Support repair and integrity decisions  

This approach enables efficient screening while ensuring accurate, actionable data for asset integrity assessment.
