Suitable sodium nitrite levels to inhibit corrosion [Missouri] 

+++++

I work at an factory that sends aerosol cans through a water bath with sodium nitrite among other things to inhibit corrosion. Does anybody know what is the recommended concentration of sodium nitrite in ppm to use as a rust inhibitor. Couldn't find anything in print to include in my training manual.
Thank so much in advance.

Dear Mr. Wallen,

I am also interested in the responses you have received to your question.

Long ago, at a company I worked, we used to add sodium nitrite to prevent rust forming on pressure vessels put in water tank to perform pressure tests.

But I cannot remember the concentration. Now at another company I want to do same...

your help / input would be appreciated.

Thanks
