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 diagram below: 1 mm = 0.03937 in. T(oF) = [T(oC)](9/5) + 32.
OxygenLeveraging the combustion-sustaining, oxidising and life-supporting properties of oxygen across the widest range of industries. Oxygen (O2) is a colourless and odourless gas. It is vital for most life forms on earth. We absorb oxygen through the air we breathe. Medical oxygen is essential in hospital and clinical care for resuscitation and surgery and for various therapies. It is also mixed with nitrogen or helium to create underwater diving mixtures. Oxygen is obtained on a commercial scale through the liquefaction and distillation of ambient air at air separation plants.
