METHOD OF CATHODE PROTECTION AGAINST CORROSION, METHOD OF ELECTRIC GROUNDING AND SET OF PARTS Russian patent published in 2000 - IPC

FIELD: anticorrosion protection of equipment. SUBSTANCE: invention refers to devices of anticorrosion protection with supply of current for elongated backing and to electric grounding of objects. Set of parts includes extended conducting element having first and second ends and incorporating continuous lengthened core containing material with specific resistance at 23 C not less than 5 x 10^-4 Ohm cm and resistance at 23 C not less than 0.03 Ohm/m and element carrying conducting polymer compound embracing and contacting core. Additional layers surround and contact conducting polymer element. Set of parts is provided with element having predominantly conical shape and conduit passing along its axis to house core and conducting polymer element as minimum by first end of extended conducting element. Conduit has shape and size ensuring snug fitting of conducting polymer element by first end of extended conducting element. Conical element has resistance as minimum equal to specific resistance of conducting polymer element. Methods of cathode protection against corrosion and of electric grounding provides for usage of set of parts mentioned above. EFFECT: prolonged service life of equipment for anticorrosion protection. 24 cl, 6 dwg
