COATING CORROSION PREVENTION STRUCTURE FOR EQUIPMENT MADE OF STEEL AND COATING CORROSION PREVENTIVE BODY

摘要

PROBLEM TO BE SOLVED: To provide coating corrosion prevention structure which can exhibit a stable corrosion prevention action on equipment which undergoes a dry state and a wet state repeatedly over a long period.;SOLUTION: In the coating corrosion prevention structure for equipment made of a steel material, a coating corrosion preventive layer 3 is formed on the circumferential face of equipment 2 made of a steel material installed in a prescribed installation place, and the coating corrosion preventive layer 3 is provided with: a corrosion protective layer 31 covering the circumferential face of the equipment 2; and a protective layer 32 covering the outside of the corrosion preventive layer 31. A gap between the outer circumferential face of the equipment 2 made of the steel material and the upper end part of the coating corrosion preventive layer 3, and the same upper end part are covered with a seal material 4, and further, a gap between the installing face G of the equipment 2 made of a steel material and the coating corrosion preventive layer 3 is coated with a seal material 5.;COPYRIGHT: (C)2009,JPO&INPIT
