Pipeline Pigging & In-Line Inspection Services
Operators cannot see inside a live pipeline. Corrosion thins the wall, cracks grow, the line shifts — and, often, none of it shows until it cannot be deferred. Dexon’s in-line inspection (ILI) fleet shows operators all of it. A sensor-covered tool travels with the product flow, recording wall condition along the entire run, often in service. Dexon runs ILI from 3 in. to 64 in., sizing cracks, corrosion, geometry and movement for just about every pipeline type and configuration.

Test With Confidence
Rental Test Yard for In-Line Inspection Tool Qualification
The largest in-line inspection test yard in Asia — available for operators or inspectors seeking a third party or the facilities to verify performance.
Qualify multiple methods for multiple threats — MFL, UT, EMAT, and emerging tools benchmarked for POD, POI and POS against industry-aligned defect libraries
Two facilities, 4-in. to 52-in. — a 150 m closed-loop pipeline in 6-in. to 24-in., plus pull and push test strings from 4-in. to 52-in., with custom sizes built on request
Your geometry, not a generic loop — custom spools with back-to-back bends, 1.5D bends, tees, reducers, dual-plane configurations, and more
Conditions that match the run — up to 15 bar and 3.3 m/s in the loop and 0.5 to 5 m/s on the pull rig, with distance, speed, pressure and pull force logged throughout
Prove endurance and passability — 32-hour or more closed-loop fatigue runs that ensure that a pig can finish the run with confidence
The Dexon Difference
Exceptional high-resolution UT data: Industry-leading specs for more precise defect-growth monitoring and fewer unnecessary shutdowns.
Tools tailored to the pipeline: Designed, built, and tested under one roof to fit operations.
Rapid turnaround for complex projects: In-house R&D, parts production, and 7-acre test facilities mean a purpose-built tool in under two months.
Inspectors with deep field expertise: 45 years in NDT and 30 in in-line inspection, alongside the industry's biggest names.
