Non-Destructive Inspection for Preventative Maintenance of Pipelines

In-Line Inspection (ILI) is a type of non-destructive inspection which denotes a preventative maintenance inspection of pipelines to identify corrosion, cracks and other defects that may result in catastrophic failure of the structure.


In-line inspection are interchangeably referred as line-inspection.


In-line inspection comprises of the use of technologically advanced tools. A common tool used for in-line inspection is ‘ultrasonic smart pig’. This tool is deployed inside a pipeline which can move easily along the full length of the pipeline. Once deployed, the pig can perform contact testing, inspections and sample collections from inside the pipeline body. It can also record data such as wall thickness and dents as it moves through the pipeline..



Using smart pigs for In-line inspections do not interrupt pipeline operation, that makes use of smart pigs vital for in-line inspection preventing the need for shut down of pipeline operation.  There have been significant advances in magnetic flux leakage (MFL) in-line inspection (ILI) technologies in recent years. These have led to improvements in Probability of Detection (POD), Probability of Identification (POI) and Probability of Sizing (POS).Ultrasonic Smart Pigs can be used to inspect any pipeline diameter, thickness and material, which include.


  • Carbon Steel
  • Stainless Steel
  • High-Density Polyethylene (HDPE)
  • GRP/GRE pipelines
  • Bare, Coated or Insulated
  • Subsea or Above Ground
  • Cladded or lined pipelines
