Nitrogen Foam Inerting

Nitrogen foam inerting is a high-integrity safety technique where hot work in the presence of hydrocarbon products is required. Nitrogen foam provides gas in a stable, visible form and has been used extensively on pipelines, tanks and
process vessels for many years, during maintenance and shutdown periods.

Foam Inerting Process

Gaseous nitrogen is converted to a high-expansion foam and, maintained under positive pressure conditions, ensures essential levels of safety during a hot cutting procedure.
This method provides:

• positive displacement of flammable vapours from within
  process vessels or pipework;
• visual indication of the inerting medium;
• rapid replacement of the foam destroyed by the heat of
  the cutting procedure.

For maximum safety, we use a specially formulated nitrogen-based foam that is injected into the vessel and the rate of foam generation is closely controlled to match the speed at which the hot work is being performed. This technique is well established, has an unparalleled safety record and enables hot work in circumstances which would otherwise be impossible.
