ANSI Carbon Steel Flanges
Description
Technical Parameters
The flange is an important part used for connecting pipes. It is attached to the end of the pipe and has various holes that enable bolts to connect the two flanges together tightly. Gaskets are used to seal the flanges to ensure that the connection is watertight. Depending on the need of the application, American standard flanges can be customized for either threaded or welded connections.
Flange connection is a type of connection that allows for easy removal. It involves securing two pipes, pipe fittings, or equipment onto a flange, which is then sealed using a gasket placed between the two flanges. By fastening bolts, the connection is completed. The utilization of American standard flange connection is crucial in pipeline construction. This advanced form of flange connection is user-friendly and has the capability to withstand high pressure. Due to its reliability, the American standard flange connection is extensively utilized across various industrial pipelines.

Slip On Flange, Weld Neck Flange, Socket Weld Flange are all types of flanges standardized by ANSI B16.5. These flanges are specifically designed for connecting pipes, valves, and other equipment in various industrial applications.
The Slip On Flange is characterized by its easy installation and removal. It slips over the pipe and is then welded on both inside and outside to provide a strong and leak-proof connection. This type of flange is commonly used in low-pressure applications.
On the other hand, the Weld Neck Flange offers better strength and structural integrity. It has a long tapered hub, which not only provides reinforcement to the flange, but also acts as an extension of the pipe. This makes it ideal for high-pressure and high-temperature applications.
The Socket Weld Flange is designed to be welded directly to the pipe. It has a recessed area where the pipe can fit snugly, ensuring a reliable and secure connection. This type of flange is commonly used for small-size pipelines and is particularly suitable for systems with high vibration or fluctuating temperatures.
Overall, ANSI B16.5 Slip On Flange, Weld Neck Flange, and Socket Weld Flange are essential components in piping systems, offering different advantages depending on the specific application requirements.




The Threaded Flange, Lap Joint Flange, and Blind Flange are all types of flanges that comply with the ANSI B16.5 standard. These flanges serve their unique purposes in various industrial applications.
Firstly, the Threaded Flange is designed with internal threads, allowing it to be easily connected to pipes or fittings with external threads. This type of flange provides a strong and leak-proof joint, making it suitable for high-pressure and corrosive environments.
Next, the Lap Joint Flange consists of two components – a stub end and a lap joint flange. The stub end is welded to the pipe, while the flange is free to rotate around it. This design allows for easy alignment and installation, making it ideal for applications requiring frequent dismantling or maintenance.
Lastly, the Blind Flange is a solid disk used to block off or seal the end of a piping system. It does not have a bore, making it an effective way to close an opening and prevent the flow of fluid. Blind Flanges are commonly used when the pipe needs to be terminated temporarily or when future expansion may be required.
In summary, the Threaded Flange, Lap Joint Flange, and Blind Flange are all integral components in the ANSI B16.5 flange standard. Each type serves a specific purpose in industrial settings, providing secure connections, ease of installation, and effective sealing options.
