Abstract

The invention discloses a real-time monitoring system for corrosion under a thermal insulation layer. The system is applied to heat preservation equipment and pipeline construction. The system comprises at least one set of preassembled test pieces, an intelligent information acquisition device, a data transmission device and a central host, the preassembled test pieces are arranged in a thermal insulation layer in thermal insulation equipment and a pipeline and is in data connection with the intelligent information acquisition device, the intelligent information acquisition device is used foracquiring data information of the preassembled test piece and transmitting the data information to the central host through the data transmission device, and the central host carries out prompting andearly warning after analyzing the data information. The corrosion real-time monitoring system has the advantages of being independent, convenient to install and high in automatic control.

Description

technical field [0001] The invention relates to the technical field of anticorrosion 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 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 insulation material and the base metal, resulting in corrosion under the insulation layer. occur. For equipment or pipelines with insulation structure installed, the probability of corrosion under the insulation layer will increase significantly after 5 years of operation. After 10 years of use, 60% of...
