Abstract

The invention discloses a real-time monitoring system for corrosion under a thermal insulation layer, which is used in the construction of thermal insulation equipment and pipelines. In the thermal insulation layer in the thermal insulation equipment and pipeline, and data connection with the intelligent information acquisition device, the intelligent information acquisition device is used to collect the data information of the pre-installed test pieces, and transmit the data information to the central host through the data transmission device, and then The central host will prompt and warn after analyzing the data information. The corrosion real-time monitoring system of the invention has the advantages of system independence, easy installation and high automatic control.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion of thermal insulation layers, in particular, to a real-time monitoring system for corrosion under thermal insulation layers. Background technique [0002] Corrosion under insulation layer refers to the corrosion phenomenon of pipes or equipment covered by insulation layer due to the entry of moisture and corrosive substances. However, during the use of the thermal insulation material and the outer protective layer after installation, the outer protective layer is damaged due to installation, operation, performance or external factors, and a corrosive environment is formed in the local area between the thermal insulation material and the base metal, resulting in corrosion under the thermal insulation layer. occur. For equipment or pipelines with thermal insulation structures installed, the probability of corrosion under the thermal insulation layer will greatly increase after 5 years of ope...
