Dexon’s Unpiggable Pipeline Inspection Archive
With over 471 unpiggable pipeline inspections completed to date, Dexon Technology offers completely
customized inspection solutions for the inspection of unpiggable pipelines. The following is a selection of
unpiggable in-line inspection case studies from Dexon’s Unpiggable or “Challenging” Pipeline Inspection
Archive.
Case Study #471: Small Diameter (3”) Long-Range Unpiggable In-line Inspection in South America
The Challenge
- 3” small-diameter inspection of a long-range 32 km distribution pipeline (Typical 3” transfer
lines run for only a few hundred meters in a single plant). - Pipeline characteristics such as weld penetration can cause significant internal diameter
restrictions in small-diameter pipelines. - A lack of previous inspection data with this being the first inspection for this pipeline.
- Online inspection required.

Case Study #327: S(P)BM Loading Line In-Line Inspection
The Challenge
- Standard inspection calls for Bi-directional inspection requiring extensive support equipment
- Surface support vessel
- Onshore and offshore pumping stations
- Onshore pumping medium storage tank and offshore slop tank
- Pumping medium treatment
- Single direction inspection required
- Online inspection required
Case Study #276: Multiple diameter underground road crossing pipelines
The Challenge
- Multiple internal pipeline diameters
- Back-to-back bends
- Lack of launchers and receivers
- Absence of prior inspection data
Case Study #087: 17 Short-Length Urban Road Crossing Pipelines
The Challenge
- No Launchers/Receivers
- High number of short pipe sections
- Low cost” simple solution required
- Time constraints
