EN 1092-1 Type B1 Raised Face RF vs. EN 1092-1 Type D Groove
What's the Difference?
EN 1092-1 Type B1 Raised Face RF and EN 1092-1 Type D Groove are both types of flanges used in piping systems, but they have different designs and functions. The Type B1 Raised Face RF flange features a raised face that provides a sealing surface for gaskets, while the Type D Groove flange has a groove that allows for the insertion of a gasket. The Raised Face RF flange is commonly used in applications where a high level of sealing is required, while the Groove flange is often used in applications where ease of assembly and disassembly is important. Overall, both types of flanges have their own unique advantages and are chosen based on the specific requirements of the piping system.

Further Detail
Introduction
EN 1092-1 is a European standard for flanges used in piping systems. Within this standard, there are various types of flanges that serve different purposes and have different attributes. Two common types of flanges are Type B1 Raised Face RF and Type D Groove. In this article, we will compare the attributes of these two types of flanges to help you understand their differences and determine which one may be more suitable for your specific application.
EN 1092-1 Type B1 Raised Face RF
EN 1092-1 Type B1 Raised Face RF flanges are designed with a raised face that provides a sealing surface for gaskets. This type of flange is commonly used in applications where a leak-tight connection is required. The raised face helps to create a tight seal between the flange and the mating surface, preventing leaks and ensuring the integrity of the piping system. Type B1 flanges are available in various materials, such as carbon steel, stainless steel, and alloy steel, to suit different operating conditions.
- Designed with a raised face for sealing
- Commonly used in leak-tight applications
- Available in various materials
EN 1092-1 Type D Groove
EN 1092-1 Type D Groove flanges are designed with a groove on the flange face that accommodates a gasket. This type of flange is commonly used in applications where the flange needs to be rotated to align bolt holes during installation. The groove provides a guide for the gasket, making it easier to align the flange and ensuring a proper seal. Type D flanges are also available in various materials, making them suitable for a wide range of operating conditions.
- Designed with a groove for gasket alignment
- Commonly used in applications requiring flange rotation
- Available in various materials
Comparison of Attributes
When comparing EN 1092-1 Type B1 Raised Face RF and Type D Groove flanges, there are several key attributes to consider. One important factor is the sealing mechanism. Type B1 flanges rely on the raised face to create a seal, while Type D flanges use the groove to guide the gasket. The raised face design of Type B1 flanges may provide a more secure seal in certain applications, while the groove design of Type D flanges may be more convenient for aligning bolt holes during installation.
Another factor to consider is the ease of installation. Type D Groove flanges are designed to facilitate alignment during installation, making them easier to install in certain applications. On the other hand, Type B1 Raised Face RF flanges may require more precision during installation to ensure a proper seal. Depending on the specific requirements of your application, one type of flange may be more suitable than the other.
Additionally, the availability of materials is an important consideration when choosing between Type B1 and Type D flanges. Both types of flanges are available in various materials, allowing you to select the most appropriate material for your specific operating conditions. Whether you require a flange made of carbon steel, stainless steel, or alloy steel, both Type B1 and Type D flanges can accommodate your needs.
Conclusion
In conclusion, EN 1092-1 Type B1 Raised Face RF and Type D Groove flanges have distinct attributes that make them suitable for different applications. Type B1 flanges are designed with a raised face for sealing, while Type D flanges have a groove for gasket alignment. The choice between these two types of flanges will depend on the specific requirements of your application, including the sealing mechanism, ease of installation, and material availability. By understanding the differences between Type B1 and Type D flanges, you can make an informed decision on which type of flange is best suited for your piping system.
