Welded corrugated pipe mechanical seal

The utility model relates to the technical field of mechanical seals, and provides a welded corrugated pipe mechanical seal which comprises a corrugated pipe set, a fastener arranged at one end of the corrugated pipe set and used for being connected with a rotating shaft, a movable sealing ring arranged at the other end of the corrugated pipe set in a hot charging mode, and a static sealing ring arranged on a shell shaft hole and used for being connected with the rotating shaft. The static sealing ring is connected with the movable sealing ring in an abutting mode. By means of the technical scheme, the problems that a traditional rotating shaft sealing structure and a sealing structure adopting spring auxiliary sealing are poor in sealing precision and short in sealing life, and the medium temperature adaptation range, the medium corrosion resistance degree, the medium pressure, the service life and the like still need to be improved are solved. 本实用新型涉及机械密封技术领域，提出了一种焊接波纹管机械密封，包括波纹管组，紧固件设置在所述波纹管组一端，用于连接旋转轴，动密封
