The new composition of inhibitors for effective protection black and color metals from corrosion by rust-preventive treatment of steam boilers was proposed. The inhibiting composition was preparared by addi- tion of urotropinum and benzotriazol in the solution of sodium nitrite. Inhibiting by means of this composi- tion is preferable to drastic refining of boilers and has made it possible to decrease expenses in its fether ex- plotation and to improve condition of work also. As the result 100% inhibition of protection steel, copper and brass from corrosion simultaneously is supported.
