The blanketing system are larely utilized in the industry in different segments to increase the lifetime, integrity and conservation of stored products, increase the storage tank lifetime and to prevent possible accidents as fire and explosion.

It is a system that consists basically removal of oxygen from inside of the tank injecting an inert gas that, in the big part of the case is the Nitrogen. Such process has a series of advantages as:

  • avoid the product loss by evaporation, since the inert pressure is bigger than pressure of product vapours;
  • non-oxydation of product, cause there is no contact with oxygen;
  • protection against tank wall corrosion;
  • avoid explosive atmosphere around the tank when the product stored is flamable;
  • reduce costs with assurance.

GASCAT has many valves for this application divided as follow:

  • first stage pressure regulating valves (JR CH, Proteu, PI);
  • blanketing regulator (CELTIC N);
  • end-of-line conservation breather vent OR pressure relief and vacuum valve;
  • emergency vents and manhole valves for inspection;
  • flame arresters and anti-detonation;
  • and other accessories.
