CL2 gas and 316L

CL2 gas and 316L

(OP)
Is a valve made of 316L suitable for CL2 gas fluid?
If it is what is the maximmum temperature?
If it is not what other alloy will do the job?

RE: CL2 gas and 316L

Have a read of the investigation report into the Festus chlorine leak by the US CSB.

A flexible hose made of st/st corroded, leading to a huge release of chlorine from a rail car. It should have been Hastalloy.

Cheers,
John.

Hi John, can you direct me where I can find the investigation report?

Thanks

RE: CL2 gas and 316L

Our company which handles specialty gas is converting cylinder valves in chlorine service from SS to hastalloy.

RE: CL2 gas and 316L



the issue is the small amount of wet Cl2 and occasionally ferric chloride that occurs in vaporized and liquid draw offs. they create havoc with the 316 ss.





RE: CL2 gas and 316L

hacksaw is right.  If you are sure the chlorine is dry and will always be dry 316ss can be used.  If there is ever a chance of getting moisture in the system you need something else. The chlorine institute has some good information on materials of construction.
