What is a weld neck flange?
А weld neck flange is a type of pipe flange commonly used in piping systems. It is designed to connect two pipes or other components together by welding. Weld neck flanges are used in a variety of applications, including water and steam systems, oil and gas pipelines, and chemical processing plants.
The weld neck flange is designed with a long tapered hub that extends from the flange face at the base of the flange. This design allows for the flange to be welded to the pipe or other components, providing a strong and reliable connection. The hub of the flange also provides a smooth transition between the flange and the pipe, allowing for a stronger weld and less turbulence in the flow of the material.
Material of WN flange
The weld neck flange is available in a variety of materials, including carbon steel, stainless steel, and alloy steel. The material used will depend on the application and the environment in which the flange will be used. Carbon steel is the most common material used, as it is strong and durable, and it is also the most economical choice. Stainless steel is more expensive but is more resistant to corrosion and is often used in applications that require greater strength or where the environment is more corrosive. Alloy steel is the most expensive but is the strongest and most resistant to wear and tear.
Weld neck flange application
When selecting a weld neck flange, it is important to consider the pressure rating and the size of the flange. The pressure rating of the flange will determine the maximum pressure that can be applied to the flange without causing it to fail. The size of the flange will determine the size of the connection that can be made between the flange and the pipe or other components.
Weld neck flanges are typically used in applications where the flange must be able to withstand high pressure and temperature. They are also used in applications where the flange must be able to withstand frequent or constant vibration or movement. In addition, weld neck flanges are often used in applications where the flange must be able to resist corrosion.
Weld neck flanges are relatively easy to install and maintain. They are designed to have a tight fit, so that the connection is strong and secure. The flange should be inspected regularly for signs of wear and tear, and any necessary repairs should be made as soon as possible.
Dimension of weld neck flange
Weld neck flanges come in a variety of sizes and dimensions. The most common sizes are Class 150, Class 300, Class 600, Class 900, Class 1500, and Class 2500. The size of the flange will depend on the application and the pressure rating of the flange.
The dimensions of the flange will include the outside diameter, the hub length, and the face. The outside diameter is the diameter of the flange at the base of the flange, and the hub length is the distance between the flange face and the center of the hub.
The face is the distance between the flange face and the center of the hub. The dimensions of the flange must be carefully measured to ensure that the flange is the correct size for the application. If the flange is too small, it may not be able to withstand the pressure or temperature of the application. If the flange is too large, it may not fit properly, or it may not be able to provide a secure connection.
