What is hydrochloric acid?

• Hydrochloric acid is a gas that vaporizes strongly in the presence of moist air and has a very irritating effect on body tissues.
• This gas has a very nasty, shooting, and suffocating smell and is transported in pressurized cylinders in the form of compressed gas with steam pressure 42 times at 21.1 0C.
• In dry conditions, hydrochloric acid is inactive and non-corrosive.
• It becomes very corrosive if it is exposed to hydrochloric acid in water.
• HCl is rapidly dissolved in alcohol and ether.
• At 1782 ° C, hydrochloric acid tends to decompose into its constituent elements, H and CL.

Available grades:

% 99.9995-% 99.999-% 99.995-% 99

Tanks and maintenance:

• Dry hydrochloric acid is transported as gas in pressurized cylinders and tube trailers.
• Cryogenic tanks are used when transported in liquid form.
• The maximum weight allowed to charge HCl in the cylinders is %65 of the weight of the cylinder intake.

Compatible and incompatible materials:

1. Pipes, valves, and other equipment for direct use with hydrochloric acid must be made of stainless steel or cast steel, or low carbon steel.
2. In some cases, carbon steel can also be used, provided the temperature is controlled and does not exceed 129 ° C.
3. In the presence of HCl moisture will eat most metals.
4. Teflon is resistant to this corrosion.
5. Smaller valves, such as those used on cylinders, are made of aluminum-silicon-bronze or Monel dose with HCl.
