Production Description
Weld neck flange is a kind of pipe fittings, which refers to the flange with neck and round pipe transition and butt welded with the pipe.The function of welding flange is: connection, sealing, convenient disassembly and installation, to ensure the stability and safety of the system. As a common mechanical connection, the flange has multiple functions and advantages of connection, disassembly, sealing, vibration isolation and pressure. It is widely used in industrial fields, such as pipes, containers, equipment and other fields, and plays a very important role in use.

Because of its characteristics, butt welded flanges show remarkable durability and excellent sealing performance, making them occupy an important position in industrial applications. This flange is particularly suitable for those working environment with large pressure or temperature fluctuations in the pipeline system, whether it is high pressure or high temperature, or extremely low temperature pipe, can withstand stably.
The main purpose of the blind flange is to block the end of the pipeline and facilitate the removal of debris in the pipeline.
Linking action
Butt welded flanges are used to connect different parts of the pipe system, such as pipes to valves, pipes to equipment, and equipment to equipment connections.
Sealing action
The butt welded flange ensures the tightness of the joint through its sealing surface to prevent fluid leakage.
Easy to disassemble and install
The butt welded flange does not need to be welded and cut during installation, which is easy to disassemble and maintain the pipeline system.
Ensure the stability and safety of the system
The butt welded flange enhances the reliability and safety of the pipeline system, and the positioning function. In some mechanical installations, flanges are used for positioning, such as in cylinder installation, where flanges play the role of connection and positioning.
