[0002] Stainless steel flange is a key connecting component widely used in pipeline systems. It is mainly used for docking and sealing between pipelines. The surface of stainless steel flange needs to be passivated during processing to improve the corrosion resistance of stainless steel flange. Since stainless steel flange has a certain weight, it is often lifted by a hanger and suspended in passivation liquid for treatment to reduce the labor and time consumed in manual handling of stainless steel flange.

[0003] Chinese Patent Authorization Announcement No.: CN206767432U provides a flange transfer hanger, which is connected to a crane through a lifting device and a first steel bar fixedly connected to the bottom of the hanger, passes through the flange hole and is used to support the flange. The hanger is composed of a second steel bar and a third steel bar; the two ends of the second steel bar are respectively fixedly connected to the end points of the first steel bar and the third steel bar and are perpendicular to them, and the third steel bar is fixedly connected to the lifting device above. It has the advantages of simple structure, optimal force, safety and reliability, and protection of the flange from damage.

[0004] In the actual use of the prior art, since the sizes or shapes of flanges are various, flanges of different sizes are prone to collision or scratching with other hard parts at the same position during passivation treatment, resulting in surface damage and affecting the appearance quality of the flange. Therefore, a hanger for passivation treatment of stainless steel flanges is proposed. Utility Model Content
