MAINTENANCE
Cleaning / Purging Equipment and Lines: Chlorine: Hot water or steam is recommended over solvents
Preferred solvent for cleaning chlorine equipment is carbon tetrachloride
Purge chlorine systems with dry air or nitrogen - take necessary precaustions to prevent contaminating an instrument air system when using dry air
Dry all chlorine equipment with nitrogen to a dew point of - 60 F
Caustic:
All materials to be thermal cut, heated, or welded should be washed with 3 % (1 N) HC1 (This includes post weld heat treatment area).
Rinse with water after acidizing.
Sandblast inside and outside of pipe or material in the area where cutting, welding, or postweld heat treatment will take place.
Re-acidize and rinse area as per above steps.
A Dow employee should test the material with litmus paper or phenolphthalein to assure that it has been cleaned and rinsed properly. The pheno will turn from a clear liquid to a pink to purple color when caustic is present.

METALS:
Dry Chlorine Service:
Service where materials will be in contact with chlorine where the moisture content is less than 5 PPM water by weight in chlorine.
Recommended Materials:
Carbon Steel - Safe at temperatures less than 155 C (311 F) Iron - Safe at temperatures below 175 C (347 F)
Dry chlorine reacts violently with hot steel
- No welding on chlorine lines that have not been isolated and depressured
- Welding cables must not be clamped to chlorine lines
WARNING:
At ordinary temperatures, dry chlorine reacts with:
- Aluminum - Arsenic -Gold - Mercury - Selenium - Tellurium -Tin - Titanium

MAINTENANCE
METALS: Wet Chlorine Service:
Recommended Materials: Titanium - High resistance to wet chlorine gas
The amount of water necessary to prevent a chlorine - titanium reaction will vary with temperature and pressure Note: Titanium is highly reactive with dry chlorine gas and liquid chlorine Storage:
Titanium equipment and materials are clearly identified (purple paint) and stored in a designated area in CA - 2 warehouse. This area is separated from other parts and locked. Material controller is responsible for this area.

MAINTENANCE
METALS: Caustic Service:
Service where materials will be in contact with caustic varying in concentration from 8.5% to 50%.
Note: High corrosion rates will be caused by elevating temperatures and / or concentrations.
Recommended Materials:
Steel Pipe - 8.5 % caustic less than 150 F and stronger concentrations of caustic below 120 F
Nickel Pipe - Concentrations above 8.5 % with a temperature greater than 120 F
Aluminum is rapidly attacked by caustic and its use should be avoided.
Miscellaneous Applications:
Heat Transfer Materials - Hot water, steam, and "Hi-Tec" salt are recommended for heat transfer applications. Avoid organic materials that react with chlorine.
Filter Elements - Wound fiber glass and sintered metal are recommended as filter elements. Avoid using polypropylene and organic materials that react with chlorine.

REACTIVE MATERIALS
Listed below are soaps, solvents, and lubricants that will react in a hazardous manner with chlorine. Hydrocarbons and silicones in general should not be used without testing and consultation with the Reactive Chemicals Committee. Also, it should not be assumed a material is safe to use because it is not on the following list. The primary concern should be to use those materials which have been approved, and avoid those on the following list:
