METHOD FOR PROTECTING DETACHABLE JOINTS AGAINST CORROSION Russian patent published in 2003 - IPC

FIELD: protection against corrosion of technical objects, especially of detachable joints of machines and mechanisms, particularly in liquid-propellant engines subjected to action of humidified sea air. SUBSTANCE: method is designed for protecting against corrosion mains pipelines for gas or liquids and(or) electrical engineering circuits of apparatuses. Method comprises steps of mounting detachable joints on apparatus; testing quality of mounting and applying onto detachable joint protective coating (with thickness 1 - 200 micrometers) of vanish AK-593 being solution of copolymer of butyl metacrylate and metacrylic acid in mixture of organic dissolvers containing added plastisizing agent. Method allows to protect against corrosion main fluid pipelines and electrical engineering circuits of apparatuses subjected to action of humidified sea air for time period more than year. EFFECT: possibility for applying safety explosion-proof coating inflammable at contact with vapors of liquid oxygen. 1 dwg, 1 ex
