Pigging & Decoking


Advanced Pigging Services

Optimizing heat transfer and improving thermal efficiency on your process heaters is critical to improving your bottom line by reducing operating costs and extending run lengths. Aligning your facility with a trusted, experienced pigging and decoking company will improve reliability and eliminate expensive premature pipe wear due to inexperienced service providers.

Maviro provides full-service pigging and decoking services for the North America’s petrochemical refineries and SAGD facilities. We use the most advanced pigging techniques to safely remove coke and other mineral deposits from piping and serpentine coils.

Our experienced operators maximize each hour with effective pig runs per hour to ensure you are back online faster than other service providers. Detailed reporting and live tracking with state of the art environmentally and code compliant pump units dramatically improve reliability and predictability on the job.

Our hand picked teams have years of experience decoking fire heater furnaces, and have logged thousands of hours working with vacuum, crude, pipe stills, coker units, Steam boilers, filtration, line flushing and commissioning, pipeline pigging, and more. Many of the current best practices for decoking used in the industry today were developed by our team.

Maviro utilizes the latest pigging technology to provide:

  • Closed loop furnace pigging
  • Laser cleaning radiant tube ODs
  • Line flushing and pipeline pigging
  • Full inventory of parts and consumables

Our closed loop pigging process uses high-volume, low pressure pumps to move pigs bi-directionally through fired heater serpentine coils and pipe. The operator progressively increases the size of the pigs to safely remove the deposits while constantly monitoring pressures and flow rates of the ambient temperature water from the climate-controlled control room.

When paired with our exclusive radiant tube laser cleaning process, the maximum heat transfer properties for your heater design will be optimized. Our process is more effective than steam air decoking and on-line spalling. In addition, you are able to perform concurrent maintenance, which makes your operations more efficient.

Our softcore pig design has varying durometer hardness paired with a multitude of different appendages, allows us to effectively remove even the hardest layer of coke while minimizing tube erosion.
