CONFORMITY CERTIFICATE

CERTIFICATE OF CONFORMITY INTERGAZSERT

Flare units are designed for emergency and continuous combustion of associated petroleum gas and natural gas or other combustible gases on gathering sites, treatment of oil&gas, as well as at oil refineries and chemical plants.

Overall view

Flare units are completed with (depending on customer requirements): 

  • modern flare tips of domestic and foreign production to provide smokeless gas combustion (as per environmental safety standards), automatic ignition system and combustion control of domestic and foreign production with a warranty period of 15-30 years;
  • flare KO drums of vessel and tubular design (pipe gas expanders) of a new type, designed to separate gas from dropping liquid and mechanical impurities, destruction of liquid plugs generating in gas pipelines;
  • stop valves, instrumentation, ladders and service platforms.


Upon customer request the Flare units can be delivered with:

1) with separate risers for high- and low-pressure gas combustion (FU type);
2) combined - with two or more risers (FCU type);
3) complete with lifting gears to bring risers to a horizontal position for repair or replacement of flare tips (UFOS type);
4) complete with lifting gears for lowering flare tips (UFO type);
5) open and closed surface flare systems.
