Different Connection Methods of Wedge Wire Screen

As we all know that wedge wire screen cylinder has various connection methods for different applications like flange connection, thread connection and welding connection. What is the difference between these connection methods? Today, we would like to introduce the advantages and disadvantages of different connection methods for your reference:

Flange connection is a detachable method of tight connection. It employs two flanges to connect pipes, valves, devices and other components into a tight piping system. It is easy to disassemble & process and forms a reliable connection to withstand low pressure or high pressure according to different application requirements. It is relatively stable in a vibrating environment.

Flange connection

Thread connection is one of the most widely used connection methods. It is suitable for medium and low pressure environments as the threaded screen is relatively stable without the need of worrying about slight leakage. It is especially suitable for occasions that wedge wire screen will not be disassembled for a long time. However, it is not recommended under vibrating and shaking conditions.

Thread connection

If we adopt welding connection, there is no need to consider disassembly. It is suitable for occasions where temperature and pressure change periodically. High temperature and high pressure may cause the flange and the thread to loosen or high frequency vibration; therefore, welding is the best choice in high temperature and high pressure environments.
