KD-26(B-125) acidification corrosion inhibitor

 

KD-26 acidification corrosion inhibitor is a kind of new oil-gas acidification corrosion inhibitor developed by our company to deal with the corrosion of hydrochloric acid or clay acid on equipment pipeline in the acidification process of oil-gas well in the oilfield. With the main features such as good corrosion inhibition effect, good compatibility with acid liquor and strong adaptability, this corrosion inhibitor is one of the ideal corrosion inhibitors for oil-gas well in the oilfield.
