What is chlorine?

  • Chlorine is a non-flammable and can be find in light greenish-yellow gas
  • Chlorine has a nasty odor and is 2.5 times heavier than air, and it is very irritating if the gas is inhaled.
  • Liquid chlorine Has amber color , one and a half times heavier than water.
    Chlorine is non-flammable in both gaseous and liquid forms. However, chlorine, like oxygen, can help burn matter. Many organic matter React chemically with chlorine.
  • Chlorine dissolves in very small amounts in water, when it reacts with pure water, it forms compounds of hydrochloric acid and hypochlorous acid (ingredients of bleaches, disinfectants, deodorants, isoxide oxides).

Available grades:

%99.999-% 99.99 – %99.9


Tanks and maintenance:

  • The Maximum allowable capacity to fill chlorine tanks %125 by weight of water at a temperature of 15.6 C0.
  • Chlorine is stored and transported in cylinders with a storage volume of less than 68 kg and also tanks with a capacity of 1000-900 kg called tank tons.

Compatible and incompatible materials:

  • At normal temperatures, chlorine doesn’t corrode steel without moisture (whether liquid or gas), and if there is moisture, there will be a lot of corrosion due to the formation of hydrochloric acid and hypochlorous acid.
  • Therefore, It should be care to keep chlorine away from moisture.
  • Containers, pipes and valves should be closed so that moisture in the atmosphere stays out of the system and does not mix with chlorine.

S – Satisfactory for use with the intended gas
C – Conditional. May be incompatible under some circumstances or conditions Contact your Praxair representative for additional information
U – Unsatisfactory for use with the intended gas
I – Insufficient data available to determine compatibility with the intended gas
O – All nonmetalic, even those considered compatible, may be ignitable in oxygen enriched environments or in other oxidizing gases. Successful
use depends upon oxygen purity, pressure, temperature, cleanliness and elimination of ignition mechanisms. Please contact your Praxair
