Advantages of using Australian Standard AS 2129 Table E Weldneck Flanges

---

Weldneck flanges offer several advantages over other types of flanges, such as slip-on flanges. Here are some of the benefits of using weldneck flanges:

Superior Strength
Weldneck flanges have a long tapered hub that provides additional strength to the connection between the pipe and the flange. The welding process creates a permanent and durable bond that can withstand high pressure and extreme temperatures.

Versatility in Accommodating Different Pipe Sizes
Weldneck flanges are available in various sizes, making them suitable for use with pipes of different diameters. The flanges can also be used with pipes of different materials, such as stainless steel, carbon steel, and alloy steel.

Secure and Leak-Free Connection
The welding process creates a strong and leak-free connection between the pipe and the flange. This ensures that the piping system is safe and efficient, reducing the risk of leaks and other safety hazards.

Easy to Install and Maintain
Weldneck flanges are relatively easy to install, and the welding process can be completed quickly. The flanges are also easy to maintain, requiring only periodic inspection and maintenance to ensure that they are in good working condition.
