Embodiment Construction
[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] Such as figure 1 As shown, the present invention is used to study the sample loading device for gas corrosion of materials in the top heat transfer and temperature control environment. The combined use of the gasket 5, the blocking plate 6 and the bolt 3 is realized. This loading device reflects the characteristics that the material is controlled by the heat transfer on the top and the corrosion occurs on the lower surface, and has the advantages of simple installation and operation of the sample and sensitive control of the sample temperature.
[0034] The sample installation groove 2 is on the bottom surface of the reaction kettle cover 1, and the middle of the upper and lower ends is provided with a rectangular clamping groove 7, and each of the four corners of the clamping groove 7 has a fixed...

The invention relates to a test sample loading device and a test sample loading method for gaseous corrosion under a top heat-transferring and temperature-controlling environment. The test sample loading device is used for researching corrosion resistance of deck steel on an oil tanker oil hold, and comprises a reaction kettle cover (1), wherein the reaction kettle cover (1) is provided with a top surface and a bottom surface; the bottom surface is provided with a plurality of test sample mounting grooves (2) which are distributed in a radial shape; the upper surface of a matched specially-shaped test sample (4) is used for carrying out heating temperature detection and the lower surface is used for carrying out corrosion detection; the loading of a test sample is finished by sequentially putting a heat-conduction gasket (5), the matched specially-shaped test sample (4) and a separation blade (6) into the test sample mounting grooves (2) in sequence and fixing by using bolts (3). The loading device and the method provided by the invention can really reflect the characteristics that a reaction material is subjected to top heat transferring and temperature controlling and the lower surface is corroded; the loading device and the method also have the advantages of simplicity and convenience for mounting the test sample, sensitivity in test sample temperature controlling and the like.
Description
technical field [0001] The invention relates to the field of metal material corrosion detection, and provides a sample loading device and method for studying gas corrosion of materials in a top heat transfer and temperature control environment. Background technique [0002] When carrying crude oil, a complex corrosive gas environment containing H2S, SO2, and water vapor will be formed in the cargo oil tank of the oil tanker, which will cause serious corrosion on the lower surface of the upper deck of the tank, causing great hidden dangers to the safe transportation of the oil tanker . Therefore, it is of great significance to study the corrosion resistance of upper deck steel in oil tanker cargo oil tanks. [0003] The transportation time of crude oil is usually very long. During the daytime, the sun shines directly on the outer deck, causing the temperature in the cabin to rise rapidly. At night, the temperature in the cabin decreases, and the temperature in the cabin also...
