Dacon offers a full suite of pipeline services, and with API 570 Certified Piping Inspectors on board can also offer full Risk Based Inspection (RBI) regimes, Fitness For Service (FFS) evaluations, and holistic pipeline integrity management and monitoring systems.
Dacon provides intelligent PIGing services in line with API 1163 for the inspection of gas and oil pipelines. The intelligent PIG, which stands for Pipe Inspection Gauge, can be used for inspection of very long pipelines with the greatest possible accuracy. The PIG works on the principles of the IRIS ultrasonic internal tube inspection system and gives information about depth, geometry and location of defects in the pipeline.
The IRISpig can be battery operated without any cables attached. 60 kilometers length of pipeline can be inspected with the self contained probe which is pushed through the pipe line with either product in the line or water. Examples of pipelines that can be inspected with this tool are very long oil- and gas pipelines as well as offshore risers on wells and platforms, short flow lines around refineries and tank farms or road, rail and river crossings.
Dacon started developing the IRISpig in 1998 because Total France and PTT-EP Thailand demanded an accurate inspection method for inspection of their pipe lines. In 2001 the first PIG was successfully completed and field tested in the full scale testing facility at the Dacon office in Thailand. In 2002 the first inspection was completed successfully in the Gulf of Thailand. Since then the PIG has proven itself through numerous jobs in most parts of the world to be a rugged and reliable inspection tool capable of reporting pipeline defects with the greatest accuracy.

| Pipeline Thickness Inspection (Intelligent Pigging) |
 The In Line Inspection (ILI) technique provides unparalleled inspection accuracy in steel and dense material pipelines. The smallest corrosion, pitting or erosion is immediately detected and measured in relation to the pipeline integrity.
If your pipeline is:
• Old and /or very corroded you should choose ILI.
• In need of very accurate /detailed inspection you should choose ILI.
• Externally inaccessible and requires full inspection coverage you should choose ILI.
• Borderline and /or close to de-rating /decommissioning you should choose ILI.
• Without launcher /receiver facilities you should choose ILI.
• Non metallic pipeline, such as HDPE, you should choose ILI.
There are techniques that may have higher ‘through pipeline’speed than ILI, but when it comes to inspection accuracy the ILI tool can provide owner or operator with the best remaining thickness data available...more >> |

| Pressure Testing |
|
Pressure testing is a way to quality assurance/demonstration of installation and helps identify damaged or defective of pipe, fittings, joints, valves, hydrants and thrust restraint systems. There are many advantages of pressure testing such as decreasing expense risks, decreasing safety risk and also decreasing healthy risks...more >>

| Pipeline Cleaning (PIG) |
The general rule for the cleaning requirement of any pipeline is that the cleaner the line the better the inspection result and less chance of any problems during inspection. Cleaning of a pipeline can be achieved in many ways, normally hard or soft bodied cleaning pigs would be run through the line until the pipe is cleaned to the desired level...more >>
