   Weld neck flange provides a long tapered hub for welding to pipes , it is used in high pressure systems and suitable for both cold and hot temperatures. Generally machined by forging method, these flanges are typically butt welded to the pipe,when you are going to buy weld neck flange, it is important to specify the pipe thickness schedule. Because the flange inside diameter will match the inside diameter of pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.

Weld Neck Flange Advantages

1. Durable connection.
2. Leakage prevention.
3. Ease of installation.
4. Testing of the pipe and joints are easier.
5. The flange face is kept away from heat affected area.
6. Suitable for high pressure and high heat applications.
7. Facilitates easy access for radiography testing to check the integrity of welding.
8. The weld connection does not interfere with flow of the fluid and reduces turbulence.
