A threaded flange is a type of flange designed with internal threads, allowing it to be connected to a threaded pipe without the need for welding. It offers the convenience of easy installation and maintenance, making it a suitable option in situations where welding is impractical or not possible.

In cases where alloy steel flanges have sufficient strength but pose challenges in welding or have poor welding performance, threaded flanges serve as a viable alternative. However, it’s important to consider the limitations of threaded flanges. They should not be used in applications involving sharp temperature changes or where the temperature exceeds 260°C or falls below -45°C, as this can lead to potential leakage issues.

Threaded flanges have a similar appearance to Slip-On flanges, but they are specifically bored to match the inner diameter of the pipe. The backside of the center opening is then threaded with tapered pipe threads of the appropriate size.

The primary advantage of threaded flanges is the absence of welding requirements, resulting in minimal additional torque applied to the pipe or barrel during flange deformation. However, threaded flanges tend to be thicker and more expensive compared to other flange types. They are particularly well-suited for high-pressure pipe connections.

Uses of EN1092-01 Carbon Steel Threaded Flanges:

Threaded flanges have a wide range of uses and are valued for their specific advantages. Here are some expanded and rephrased uses of threaded flanges:

Easy Installation: Threaded flanges are highly sought after because they can be fitted onto pipes of various sizes without the need for welding. This feature makes installation quick and straightforward, saving time and effort.

High-Pressure Applications: Threaded flanges are commonly employed in applications with extremely high pressure, especially when it is not feasible to perform post-weld heat treatment. These flanges provide a secure and reliable connection, even at or near atmospheric temperatures.

Small Diameter Piping: Threaded flanges are particularly well-suited for small diameter piping applications. Their threaded design allows for a compact and efficient connection in systems where space is limited.

Non-Cyclic Applications: Threaded flanges are primarily designed for non-cyclic applications, meaning they are intended for use in systems where there are no significant fluctuations in pressure or temperature. They provide a stable and secure joint for consistent operating conditions.

Hazardous Welding Environments: Threaded flanges find utility in environments where welding poses a hazard. In areas with high explosion risks or where welding is prohibited, threaded flanges offer a safe alternative for joining pipes without the need for welding equipment or specialized personnel.

Highly Explosive Areas: Threaded flanges are suitable for use in highly explosive areas where even the slightest spark from welding could ignite hazardous substances. By eliminating the need for welding, threaded flanges reduce the risk of ignition and ensure safety in such volatile environments.
