Will a chloride content of 125PPM have an impact on carbon steel equipment?
Thread Content
Recently, it was found that in the company’s stainless steel sump tanks, which are heated using 80-degree hot water, hundreds of leakage points have appeared multiple times at the welds of the heating tubes. Moreover, after welding repair, cracks will extend around the solder joint the day after. . p+ ?9 x9 E& k' V) u Test hot water and tap water. The conclusion is that the chlorine content is severely excessive, reaching 125 ppm. It has now been found that this type of leakage is occurring in two stainless steel sumps. The hot water storage tank is made of carbon steel; it is heated using secondary steam, and there is a lot of rust inside. Is this related to chloride ions? 9 i( u- w% D# J7 o$ X Recently, efforts have been made to upgrade this hot water system, with the intention of using deionized water instead of tap water. m’ n. ] By the way, is it harmful to human health to drink water with a chloride concentration of 125 ppm?
125 ppm will have no effect on carbon steel equipment! 1250PPM is probably not a big deal either!
Chloride ions cause much greater corrosion of stainless steel than of carbon steel!!
125 ppm is a very small amount; it has practically no effect. It’s probably the heating process that causes corrosion； It’s also possible that your water is not clean. 125 ppm has no effect on humans, as the concentration in tap water consumed is higher than this.
There must be corrosion! , especially for stainless steel! Strengthen water quality management!
