Max chlorine content in water for hydrostatic test carbon steel

Max chlorine content in water for hydrostatic test carbon steel

Max chlorine content in water for hydrostatic test carbon steel

(OP)
Hi, i'm new engineer in petrochemical plant. i have a problem about chlorine.

We want to press test ammonia tank with hydrostatic method. We want to re-use blow down water from cooling water. The properties of cooling water are:
pH : 7.8
Cl : 415 ppm
Mg hardness : 300 ppm CaCO3
PO4 : 5.8 ppm

material for ammonia tank is Carbon Steel A537 Class 1.

I have searching for standard max chlorine content, but always found standard for stainless steel (API570). I still search standard or rules for max chlorine content in water for hydrostatic test Carbon Steel to avoid corrosion after hydrostatic test. Does anybody can help me give the standard :) ?

Best regards,

-Yadi-

RE: Max chlorine content in water for hydrostatic test carbon steel

You are talking about chlorides, not active chlorine, that is different.
What time period is involved?
How clean is the rinse water available?
If you will be leaving any residual this water is unsuitable.

Chloride at these levels is of little to no concern for testing carbon steel. For stainless steels, you'd be worried about it accumulating on evaporation, leaving enough somewhere to initiate chloride stress corrosion cracking.
