PROPERTIES AND APPLICATIONS:
Property Application or Benefits
Non-sparking Appropriate for explosive potential environment such as oil and gas works, petro-chemical plants, etc. It can efficiently avoid spark arising while operating.
Non-magnetic safety Essential for equipment that require complete non-magnetic environment.
Corrosion resistant Especially well suited for applications in corrosive environments like encountered in marine works or firefighting applications.
Forged after casting Provide higher mechanical properties and better finishing.
Applications:
MAIN APPLICATION FIFLSDS
Petrochemicals Chemical Industry Mines
Refineries Fireworks Industry Defense
Gas& Oil pipe lines Flour silos and mills Air Forces
Power stations Breweries Navy
Paint Manufacturing Destillery Aerospace Industry
Pharmaceutical Industry Fire-fighters Automobile Industry

Zone0 Zone1 Zone2
Gas, Oil, Mist or Vapor Refers to a dangerous atmosphere in which a mixture of air and flammable substances in the form of gas, mist or vapor is present frequently, continuously or for long period. Refers to a dangerous atmosphere in which a mixture of air and flammable substances in the form of gas, mist or vapor is likely to occur occasionally under normal operation. Refers to a dangerous atmosphere in which a mixture of air and flammable substances in the form of gas, mist or vapor is not likely to occur under normal operation, but if it does occur, will persist only for a short period.
Dust Zone20 Zone21 Zone22
Refers to a dangerous environment in which a cloud of combustible dust in the air is present frequently, continuously or for long period. Refers to a dangerous environment in which a cloud of combustible dust in the air is likely to occur in normal operation occasionally. Refers to a dangerous environment in which a cloud of combustible dust in the air is not likely to occur in normal operation, but if it does occur, will persist for only a short period.
