Regular Flanges
Threaded Flange
- No Welding Required: Threaded connection eliminates the need for welding during installation
- Easy Disassembly: Suitable for applications requiring frequent disassembly
- Minimal Additional Torque: Small additional torque on pipes when flange deforms
- Reliable Sealing: Threaded connection ensures good sealing performance
- High-pressure Application: Suitable for high-pressure pipe connections
- Flexible Installation: No special welding equipment required, flexible installation
Threaded Flange is a type of flange that connects to the pipe through threads, suitable for high-pressure pipe connections. The flange can be treated as a loose flange during design, with the advantage of not requiring welding and producing minimal additional torque on the cylinder or pipe when the flange deforms. Threaded flanges connect through internal threads with external pipe threads, making installation convenient, especially suitable for applications requiring frequent disassembly. They are widely used in high-pressure and high-temperature pipe connections in industries such as petrochemical, power, and shipbuilding.
