Choosing the right flange type is essential for your project’s success. Two types of flanges that are commonly used are flat-face and raised-face flanges. Each has its own advantages, so it’s essential to understand the differences between them before you make your selection. Let’s take a closer look at the flat face and raised face flanges.
Flat Face Flange
A flat face flange is characterized by a flat gasket surface on both sides. This flange can be used in applications where a tight seal is not required, such as when connecting two pipes with different diameters or an irrigation system to a water source. The advantage of using this type of flange is that it eliminates the need for additional sealing agents, making installation much easier and faster.
Raised Face Flange
A raised face flange has a raised gasket surface on one side and a flat gasket surface on the other side. This flange type is ideal for applications requiring a tight seal, such as plumbing systems, petrochemical plants, and power plants. The advantage of using this type of flange is that it creates an airtight seal around the connection point, preventing any leaks or contamination from occurring.
Difference Between Flat Face and Raised Face Flange
Advantages of Flat Face Flanges
One advantage of flat face flanges is that they are less likely to leak than raised face flanges. This is because the flat surface provides a better seal than the raised surface. Additionally, flat face flanges are easier to install than raised face flanges.
Advantages of Raised Face Flanges
One advantage of raised face flanges is that they provide a better seal than flat face flanges. This is due to the fact that the increased surface offers more contact with the pipe, which creates a tighter seal. Additionally, raised face flanges are more resistant to corrosion than flat face flanges.
Disadvantages of Flat Face Flanges
One disadvantage of flat face flanges is that they are more likely to leak than raised face flanges. This is because the flat surface does not provide as good of a seal as the raised surface. Additionally, raised face flanges are easier to install than raised face flanges.
Disadvantages of Raised Face Flanges
One disadvantage of raised face flanges is that they are more difficult to install than flat facefl ates. This is because the raised surface must be appropriately aligned with the pipe to create a seal.
The flat face and raised face flanges each have unique advantages depending on what they are used for. It’s important to consider all factors before deciding which type of flange is best for your project. Understanding these differences will help you decide which type of flange will best suit your needs. Whether you choose a flat or raised face flange, rest assured that with the right knowledge and application, you will succeed in achieving an airtight seal for your project!
