RUST PREVENTING APPARATUS OF COUPLER BASE FOR ASSEMBLING OF INSULATION BOX OF LIQUID CARGO TANK IN VESSEL

摘要

The present design maintains airtightness by discharging air through a vent pipe penetrating through the protective cap covering the connector, and at the same time maintaining airtightness of the coupler base used for fastening the insulation box by allowing the rust inhibitor to be formed inside the connector. It relates to an anti-corrosion device of a connector base for fastening an insulation box of a liquid cargo hold in a ship so that rust prevention can be achieved at once.
