[MW:4582] corrosion problem in TP321 pipes after hydrotesting

Hi,
We have a 2"Sch-40 A312TP321 piping .We tested the above line 4 months before partially and accepted. Same line when we tested again now it started leaking at several locations(welds and pipe)We tested the water used for testing the line and found that the chloride content is 120ppm
Is it possible that just because of this high chloride content the line starts leaking within 3 months?
 
best regards,
BIJU
