Understanding Slip-On Flange and Weld Neck Flange in Piping Design

When it comes to piping design, two common types of flanges are slip-on flanges and weld neck flanges, each serving different purposes in connecting pipes. Let's break down the differences between the two:

Slip-On Flange

A slip-on flange is a type of flange that has a bore slightly larger than the outer diameter of the pipe. It is slipped over the pipe and then welded in place to provide strength and prevent leakage. Slip-on flanges are ideal for low-pressure applications and non-critical connections.

Weld Neck Flange

On the other hand, a weld neck flange has a tapered hub that is welded to the pipe, providing reinforcement and allowing for better flow efficiency. Weld neck flanges are ideal for high-pressure and high-temperature applications, as they distribute stress more evenly and reduce the risk of leakage.

In summary, the main difference between a slip-on flange and a weld neck flange lies in their connection methods and application suitability. Slip-on flanges are easier to install but may not be suitable for high-pressure systems, while weld neck flanges offer superior strength and are preferred for critical applications.

Understanding the distinction between slip-on and weld neck flanges is crucial in ensuring the proper selection of flanges for different piping design requirements.
