[0002] A flange is a component that tightly connects the ends of two pipes or equipment using bolts and nuts, primarily serving a sealing and fixing function. It is widely used in pipeline systems in industries such as chemical, petroleum, power, and metallurgy. Based on the connection method, material, and application, flanges can be divided into several types: Slip-on flanges: Features: Connected to the pipeline via fillet weld; simple structure; low manufacturing cost. Suitable for: Connections of medium and low pressure vessels and pipelines. Butt-welded flanges: Features: Neck design; welded to the pipeline via butt welding; good sealing performance; high rigidity. Suitable for: Pipelines operating at high temperatures, high pressures, low temperatures, or containing flammable or explosive media. Socket-welded flanges: Features: The pipe end is inserted into the flange ring and welded; good rigidity; excellent sealing performance. Suitable for: Applications with pressures of 1.0-10.0 MPa. Flanges are key components used in the industrial field to connect pipes, valves, pumps and other equipment. Their design aims to ensure sealing and stability. After the flanges are processed in the workshop, they are supported by pallets. The flanges are stacked on the pallets in an upright state. At this time, the flanges are exposed and are not only easy to tip over, but also susceptible to damage from external impacts, resulting in poor protection. Therefore, the inventor proposed a flange protection device. Utility Model Content

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention benefits from the design of the lifting rod and support rod, which allows for the rapid support of the processed flange. The lifting rod's mobility enables it to slide into the carrying box, while the side limiting plate restricts the flange's position on the outside of the support rod, ensuring stable storage within the carrying box. This prevents the flange from tipping over during transport, providing strong stability. Furthermore, the flange's retractable design, combined with the carrying box's protective features, offers greater safety and stronger protection compared to existing technologies where the flange is directly exposed on the pallet. This design is widely applicable. Attached Figure Description
