What causes localized deformation of the shell of tower equipment?
Local deformation of tower-type equipment during normal operation is very rare; it is more common to be caused by localized stress during manufacturing, horizontal hydrostatic testing, transportation, and other processes.
Since the device has undergone local deformation, the material must have shifted from elastic to plastic deformation, resulting in a deterioration of the local material properties; therefore, the root cause must be identified.
Answer: 1. The equipment housing is locally corroded or overheated. 2. There are openings in the housing, with no reinforcement plates or insufficient reinforcement. 3. The cross-shaped welds cause stress concentration during welding.
In addition to defects in the manufacturing process of the equipment itself (such as material quality, fabrication quality, heat treatment), there are also process-related issues (such as excessive temperature and pressure, corrosion)
