1. What is a Weld Neck Flange?

A weld neck flange is a type of flange with a long tapered hub that is welded to the end of a pipe. This design allows for smoother flow and reduces stress concentration around the piping system.

2. Advantages of Weld Neck Flanges

Weld neck flanges offer several advantages:

  • 1️⃣ Improved Structural Integrity: The continuous weld provides a solid connection that reduces the chances of leakage.
  • 2️⃣ Versatile Applications: They are suitable for high-pressure and temperature applications.
  • 3️⃣ Reduced Corrosion Risk: Their welded nature minimizes the risk of corrosion found in threaded options.
