Water Tube Corrosion
Definition - What does Water Tube Corrosion mean?
Water tube corrosion is a phenomenon where water tubes (such as copper) are affected by erosion corrosion, otherwise known as impingement damage. It is typically caused by the fast flow of turbulent water, and is one of the major causes of failure in water piping and distribution systems.
To prevent this type of corrosion from occurring, water conditions should be evaluated along with other factors that affect the performance of water tubes.
Corrosionpedia explains Water Tube Corrosion
Water tubes such as those made from copper are widely used to distribute water. On rare situations, the conditions of the water can affect the integrity of water tubes.
However, there are cases where the corrosion is brought about by chemical factors. In such instances, water systems and related industries should implement cost-effective and viable water treatment programs to mitigate the corrosion concerns in water tube systems.
Some of the common corrosion problems that can be found in water tube systems include:
- Hot water pitting induced by manganese, iron and aluminum
- Cold water pitting induced by sulphide and carbon dioxide
- General corrosion (green/blue water concerns)
- Erosion corrosion
In order to resolve the problem, solutions such as the application of solders as well as appropriate operation and system design should be implemented. The over-usage of flux under certain situations should be prevented as well.
In addition to proper water tube installation, a number of highly effective water treatments are suggested to mitigate the corrosion process in water tube systems.
