1. Connection function: Flange screws form a stable connection point by fastening the flange to the equipment or pipeline. The tightening effect of flange screws allows the flange to withstand the pressure and weight on the pipe or equipment and ensures the reliability of the connection.

2. Sealing: The tightening of flange screws makes the flange connection have high sealing performance, which can avoid leakage of liquid or gas. This is especially important for some pipeline systems where sealing is important.

3. Flexibility: The number and length of flange screws can be selected and adjusted according to specific needs, so it has a certain degree of flexibility. This allows the flange connection to be suitable for pipes or equipment of different diameters and materials.

4. Easy maintenance: The fastening structure of flange screws makes the maintenance and replacement of the equipment easy. When the flange connection needs to be maintained or replaced, the flange can be disassembled by simply loosening the screws to facilitate subsequent maintenance work.

5. Various materials: Flange screws can be made of different materials, such as stainless steel, carbon steel, alloy steel, etc. According to actual needs, materials suitable for specific working conditions can be selected to meet the use requirements in different environments.
