What is a threaded flange
Threaded flange is a universal pipe connection method.
The flange connection adopts a threaded structure, which can provide good sealing performance. Usually used to connect small pipes with diameters below DN50.
What types of threaded flanges are there?
Threaded flanges can be classified according to different standards, there are mainly three types:
- According to the connection method of the flange, the threaded flange can be divided into two types: internal threaded flange and external threaded flange.
- According to the material of the flange, threaded flanges can be divided into three types: steel threaded flange, stainless steel threaded flange and copper threaded flange.
- According to the flange standards, it is mainly divided into various types such as GB/T9112-2000, GB/T 6174-2008, JB 4700-2000 and JB/T 81-1994.
Threaded flange connection method
There are three main ways of connecting threaded flanges:
- The internal threaded flange and the external threaded flange are connected to each other to connect the pipes together.
- Sealing connection between threaded flange and threaded pipe.
- The threaded flange with sealing gasket is matched with the threaded flange to provide good sealing.
What should you pay attention to when using threaded flanges?
When using threaded flanges to connect pipes, attention should be paid to selecting corresponding materials and standards to ensure the reliability and sealing of the connection.
In order to avoid problems such as leakage or loose joints, the appropriate torque value should be selected for installation according to the actual situation.
Check whether the sealing gasket of the threaded flange matches the sealing surface to ensure the sealing effect during connection.
When connecting threaded flanges, keep the threads clean and smooth, and use appropriate sealant to increase the sealing of the connection.
In short, threaded flange is a common pipe connection method with good sealing performance and reliability.
During use, attention should be paid to selecting appropriate materials and standards, and connecting pipes in the correct method to ensure safe and reliable connections.
