| Abstract: | This paper has analyzed the reason of bolt fracture in refinery hydrotreating unit combined hydrogen compressor cavity clearance. Based on macroscopic examination, strength analysis, bolt material composition analysis, metallographic inspection, hardness detection, electron microscope examination on bolt fracture and thread, it is obtained that the improperly mechanic processing is the main reason to cause bolt fracture. The solutions and precautions are also pointed out. |
