Understanding Table E Flange Dimensions in MM
Table E flanges, also known as raised face flanges, are a type of pipe fitting used to connect pipes or vessels. The dimensions of these flanges, including the bore (internal diameter), outer diameter (OD), and thickness, are crucial for ensuring a proper fit and leak-free connection. In this article, we'll delve into the dimensions of Table E flanges, focusing on the metric system (millimeters).
Table E Flange Sizes and Dimensions
Table E flanges are available in a wide range of sizes, typically ranging from DN15 (15 mm) to DN600 (600 mm). The dimensions of these flanges are standardized and are based on the pipe size they are intended to fit. The most common dimensions include:
- Bore (DN): This is the internal diameter of the flange, which corresponds to the pipe size.
- Outer Diameter (OD): This is the overall diameter of the flange, including the hub and the facing.
- Hub Height: This is the height of the hub, which is the raised part of the flange that fits into the pipe.
- Hub Thickness: This is the thickness of the hub, which is the part of the flange that fits into the pipe.
- Facing Thickness: This is the thickness of the facing, which is the flat part of the flange that sits against the mating flange.

Factors Affecting Table E Flange Dimensions
While the above dimensions are standardized, there are several factors that can affect the dimensions of Table E flanges:
- Material: The material of the flange can affect its dimensions. For instance, flanges made of high-strength materials may have thicker hubs and facings.
- Pressure Rating: The pressure rating of the flange can also affect its dimensions. Higher pressure ratings typically require thicker flanges.
- Temperature: The temperature of the fluid being carried can also affect the dimensions of the flange. Higher temperatures may require thicker flanges to withstand the heat.
Choosing the Right Table E Flange
When choosing a Table E flange, it's crucial to consider the pipe size, pressure rating, and temperature of the fluid being carried. Using the wrong flange can lead to leaks, poor performance, and even catastrophic failure. Always consult the manufacturer's guidelines and ensure that the flange meets the relevant standards and regulations.
Understanding the dimensions of Table E flanges is crucial for ensuring a proper fit and leak-free connection. Whether you're a seasoned engineer or a DIY enthusiast, this guide should provide you with the information you need to select the right flange for your needs.
