Maximum Chloride Content for test water
(OP)
Dear Friends,
does anyone of you know what is the maximum chloride content for test water for Carbon and low alloy steel piping? On the web I found one paper which states 30 ppm, but I would prefer code/standard reference if possible.
Thank you

Technically, the glass is always full - 1/2 air and 1/2 water.

DEP strikes again!
If DEPs are not your job spec, toss them.
Fresh water (typical city water in United States) < 100 ppm
EPA recommended limits are 500 ppm
In other words, you can't taste that 30 ppm salt content!
Sea water contains 30,000 ppm
I've left 100s of miles of subsea pipeline with saltwater hydrotest inside for up to 6 months. 30 years later, still flowing gas.

Colorado River Water can be over 1000 ppm Chloride.

Simple draining and drying might not have removed the salt, possibly leaving concentrated salt deposits near welds and seams. Were the lines pigged and flushed with fresh water before drying? Was the resulting salt content of the fresh water tested for chloride content?

"Equipment manufactured from carbon steel or low-alloy steel may be hydrostatically tested
with potable, brackish or salt water as available. If potable water is not used, the test water
shall be completely drained and the equipment flushed with potable water immediately after
testing and thoroughly dried with hot air or steam."

DEPs I apologize.. just this once.
Actually they're not all that bad, when used correctly.
