Seeking guidance on the inspection contents and methods for heat exchangers
Reference can be made to the relevant content in the second volume of the \"Chemical Engineering Machinery Maintenance Manual\", and then formulate plans based on the actual conditions of the respective unit.
Inspections during normal production: ①Externally visible defects: corrosion, welding defects, damage, etc. ②Leaks at the connections between the shell and the head flange, between the pipelines and the shell flange, between the valves and the pipeline flanges, as well as at the seals of the valve covers. ③Condition of the supports and structural elements, as well as the foundation. ④Insulation condition. ⑤Check the operation records to assess operational status. ⑥Determine whether there are leaks based on the production conditions
