Abstract

The invention relates to an experimental device for simulating corrosion of a crude oil tank of a goods oil tanker. The experimental device comprises a CO2 (Carbon Dioxide) gas bottle, a O2 gas bottle, an H2S gas bottle, an SO2 gas bottle, an N2 gas bottle, a gas flow controller, a ventilating guide tube, a mixed gas exhaustion device, a gas outlet valve, an experiment cavity cover, a flexible heating board, an experiment cavity, a water-solubility heater, a heating rod, a residual gas recycling container, a first temperature controller and a second temperature controller, wherein the water-solubility heater has an inner cavity as an experiment cavity; distilled water is poured inside the experiment cavity, and space is provided between the experiment cavity and the top part of the experiment cavity; the experiment cavity is sealed by the experiment cavity cover; the flexible heating board is arranged inside the lower space of the experiment cavity cover; and a test sample is fixed below the flexible heating board. The experimental device can truly simulate drying-wetting alternative working conditions of gas at an inside top plate of a tanker compartment under different temperatures, and has a simple structure.

Description

technical field [0001] The invention belongs to the field of accelerated simulation testing instruments, and relates to the test of the gas corrosion performance of steel in the environment of the tanker cabin, specifically an accelerated simulation of the corrosion performance of steel materials by simulating the roof gas inside the tanker cabin under factors such as dry-wet alternation and temperature. Test device and its experimental method. Background technique [0002] At present, my country has become the second largest oil consumer and the third largest oil importer in the world. Of the hundreds of millions of tons of oil imported each year in my country, more than 90% are transported by foreign tankers. It is obviously unstable and uneconomical to use foreign ships to transport most of China's imported oil. Therefore, the Ministry of Communications of China clearly put forward the "maritime power strategy", pointing out that China must build its own strong internati...
