Watertreatment against Corrosion


Today water in the industry is still most frequently transported in metallic pipes or systems. The simpler the iron or the carbon steel pipe the greater the risk of corrosion. The definition of corrosion is an (unwanted) reaction of materials with substances present in their environment. In the case of iron, this reaction becomes visible for instance when rust forms. The reasons for this corrosion are diverse and are covered very extensively in the pertinent literature; we won't go into that any further in this article.

Pursanova TM yields safe and reproducible results where the less complicated reasons for corrosion between water and iron are on hand. These simple reasons are either stagnating water or water which is poor in minerals or unsaturated. A good example of unsaturated water is feed water to hot water boilers or steamboilers , where the problem of corrosion in very often found. Even pitting is reduced in a lot of cases.

Corrosion due to galvanic couples, alkaline or acescent fluids is at least moderated by Pursanova TM In most cases it can even be stopped completely when certain favorable combinations are on hand. But such complicated applications require thorough technical scrutiny. We are glad to answer any of your questions via email. Pursanova TM perceives corrosion in pipes and machines as the most pressing problem of our customers worldwide. Damages caused by corrosion are the main reason for expensive emergency shut downs or replacement investments.

Latest results from the field show for instance a reduction of the corrosion rates (MPY ), even in oil pipe lines, by more then 10 times .
