METHOD FOR EVALUATION TEST OF CORROSION RESISTANCE OF INNER SURFACE OF UPPER DECK CARGO TANK IN ACTUAL SHIP

摘要

Increases the reproducibility of the temperature fluctuations, if the high precision in terms of the corrosion rate and evaluate it and corrosion evaluation test methods can actually ship upper deck cargo tank inside which, cargo tankers of the actual ship, manhole or cleaning the hall door facing the atmosphere in the cargo tanks on, the corrosion test piece, the temperature variation of the corrosion test surface in the corrosion test piece is, the cargo tank cargo tank inner wall of the lower side of the upper deck, or to the cargo equal to the temperature variations in the cargo tank structure the surface of the tank top deck and so fixed, the corrosion test piece, characterized in that the cargo tank exposed to the atmosphere. ;
