Corrosion is basically the reverting of a metal to its ore form. Corrosion at some point in time is probable with all products that are made from steel or iron.
Boiler corrosion generally occurs when the boilers water alkalinity is low during routine operations. If left untreated, it can affect the boiler and result in complete equipment failure. These tips will help you keep your boiler running smoothly for years without corrosion.
What Causes it?
Although boilers are common equipment for a homeowner, people are unaware of preventative methods used to keep boiler corrosion to a minimum. The oxygen in water creates holes that can leak water and create oxidisation.
There are two types of boiler corrosion – Caustic corrosion & Acidic corrosion. Caustic corrosion is caused by steam blanketing, Acidic corrosion can be caused by mishandling of chemicals during cleaning operations. So no matter what type of corrosion your boiler has, it is important to take preventative steps.
How to minimise it?
You can’t stop it completely, but you can minimise some effects and by doing so extend the life of your boiler. Treating the water that goes into the boiler is the most effective, preventative method. Additives ensure oxygen makes its way to the water and is rapidly absorbed before it forms corrosive cells and blisters.
Never attempt boiler work as it is extremely dangerous. Always contact a professionally qualified engineer, they will be able to recommend the best course of action needed to prevent the corrosion – before your boiler stops working altogether.
