Steel Pipes - Corrosion due to Oxygen
The influence of oxygen concentration and temperature on the corrosion of steel pipes.
Corrosion of steel is strongly affected by the amount of oxygen in the water and the temperature of the water. The effects of oxygen and temperature on low-carbon steel pipes with water flow are indicated in the diagrams below:
- 1 mm = 0.03937 in
- T(oF) = (T(oC))(9/5) + 32
- 1 ppm = 1 mg/liter
The diagrams indicates clearly how important it is to avoid continuously fresh water supply in higher temperature systems - like heating systems or similar - where the piping is made of carbon steel.
