INHIBITOR FOR PROTECTION OF STRUCTURAL STEELS FROM CORROSION AND MECHANICAL FAILURE IN HYDROGEN-SULFIDE METALLIZED MEDIA Russian patent published in 2001 - IPC

Abstract RU 2176686 C2

FIELD: protection of metals from corrosion and mechanical failure in hydrogen-sulfide mineralized media. SUBSTANCE: inhibitor includes the following amounts of components, vol.%: complex 1,2,4-bistreazolylmethane-NiCl2, 5-15; butanol, 45-60; water, the balance. Degree of protection of structural steel (steel 20) with inhibitor in hydrogen-sulfide medium with concentration of 100 mg/l is 97.9% from common corrosion, 90.6% - from hydrogen-sulfide cracking, and 37.4% - from corrosion fatigue. EFFECT: higher efficiency of inhibitor, reduced labor input in inhibitor production. 3 tbl, 4 ex
