The corrosiveness of acetic acid
Thread Content
The condenser coil is clogged, and I want to clean it using acetic acid. The material is carbon steel; I’d like to know what the level of corrosivity is
Acetic acid is a weak acid, so there should be no problem!
There shouldn’t be any problem! But it shouldn’t be washed for too long!
During pickling, a coupon test can be conducted to determine the degree of corrosion
Although acetic acid is a weak acid, it has strong corrosiveness. However, it is not very effective for cleaning scale; generally, hydrochloric acid combined with corrosion inhibitors is used for cleaning, and this method yields good results in a short amount of time.
What substance caused the coil to get clogged? Can I do without acetic acid?
First, determine what the substance causing the blockage is; it is best not to use acetic acid for treatment. The pipeline is made of carbon steel, and acetic acid is highly corrosive to carbon steel, leading to pitting corrosion. The damage this can cause to the pipeline is evident. For blockages, I personally recommend trying steam or knocking on them manually.
It is recommended not to use acetic acid; nowadays, professional manufacturers use oxalic acid along with corrosion inhibitors for cleaning, and some use specialized cleaning agents – you can search for this information online.
Acetic acid is not recommended due to its strong corrosiveness~
Acetic acid must never be used, as it is too corrosive; first, it is necessary to determine what substance is causing the blockage. Inorganic acids plus corrosion inhibitors work.
