We have done hydrotest of carbon steel pipe with water which contains 300 ppm chlorine and hydrotest last 24 hour . now we want to use another type of water and increase chlorine concentration . how much chlorine my be corrosive for our pipe ? 1000? 2000 ppm? or more? Is there any limitation for chlorine concentration? we know that stainless steel is Sensitive to chlorine but how about carbon steel?can we allow to use any water for hydrotest without considration of it's chlorine?

Mary: Do you mean residual chlorine or inorganic chlorides? It makes a difference. With respect to chlorides, they are more damaging to stainless steel than carbon steel. Most specifications we have seen refer to a maximum chloride content of 50 ppm. Of course, any hydrotest water should be drained and thoroughly dried as soon as possible, due to the possibility of MIC corrosion. Hope this helps! David Hendrix The Hendrix Group Inc.
