Nitrogen foam inerting is a technique which provides a safe working environment for carrying out hot works and maintenance in the presence of hydrocarbons. Nitrogen foam inerting solution, is fast, reliable and cost-effective and eliminates the risk of hydrocarbon explosions.
Nitrogen foam has been used extensively on tanks, pipelines and process vessels for many years during maintenance and shutdown periods. By converting gaseous nitrogen into a high expansion foam and continuously injecting it into the system, any flammable vapours and oxygen are replaced by the nitrogen. This rapidly creates an inert and safe atmosphere, allowing maintenance works to be carried out on systems which would otherwise not be possible.
ADVANTAGES OF NITROGEN FOAM INERTING
- Replacement of flammable vapours inside a system
- Hot work can be carried out safely
- Faster than cold cutting methods
- Systems are made rapidly inert
- Nitrogen foam mixture is biodegradable
- Nitrogen foam is stable and visible
- No risk of explosion
