FIELD: chemicals compositions.
SUBSTANCE: invention relates to compositions of chemicals for corrosion inhibition and can be used, in particular, at power facilities to protect internal heating surfaces from dissolved corrosive gases in the feed water of drum steam boilers at thermal power plants. The corrosion inhibitor contains, wt.%: N,N-diethylhydroxylamine 10-20; aminoethanol 5-10; sodium hexametaphosphate 7-8; sodium metasilicate 2-5; the rest is water.
EFFECT: creation of a multifunctional corrosion inhibitor with combinations of components that provide effective corrosion inhibition of carbon steel.
