Description of key information
For dry chlorine gas (20 mg H2O/kg), steel is the usual container material. For liquid and cold dry chlorine gas, fine grain carbon steel should be used, taking into account the possibility of depressurizing the system. For wet chlorine gas, the usual materials are titanium, rubber lined steel, glass reinforced polyester resins (GPR), PTFE lined steel, PVC externally reinforced with DRP and PVDF. Chlorine should not be transported in mild steel or aluminium under wet conditions.
