Pipelines are regularly cleaned to ensure that operators can maintain their product specifications. This also improves the integrity and lifespan of the pipelines themselves. The results of our pipeline cleaning techniques are evident from internal pipeline inspections, improved product quality and increased flow rates.


We offer a wide range of Pipeline Services including:

  • Pipeline Inspections (ILI)
  • Pipeline Integrity Consultancy (Pipe Care)
  • Pipeline Pigging, Testing & Drying
  • Pipeline Pneumatic Testing
  • Pipeline Leak Testing
  • Pipeline Cleaning Online & Offline
  • Pipeline In-situ Coating
  • Pipeline Chemical Cleaning
  • Pipeline Decommissioning

Internal Cleaning and Coating Application System (Insitu)

Over time, the internal surfaces of steel pipelines are subject to the formation and build-up of aggressive corrosive deposits. These deposits facilitate internal pipeline corrosion and create surface friction that reduces throughput. The costs of treatment programmes such as inhibitors increase with pipe age as their effectiveness declines. Left unchecked, internal corrosion will shorten pipeline life and increase the potential for leaks and pipeline failure.

Underground Leaktesting

Underground pipelines and storage tanks (UGST) are pressurised with Helium. Due to its high mobility, helium can escape through small leaks and can migrate to the surface. Here it can be easily detected by the PHD-4.
