The degree of the corrosion resistance of some metallic and non-metallic materials to the vinegar was studied, and it was found that the 18-8 stainless steel and the polyethylen were the most suitable material for the treatment of the vinegar.
Amine-type corrosion inhibitors have been used for protecting the pumping wells in In-nai and Ni-i-tus oil fields. Study was made on comparing the statitsically sum up of the material replacements in the inhibited period to the non-inhibited one. The survey indicates that the use of inhibitors has resulted in the decrease of 50% material replacements.
