Swivel flanges are an essential component in piping systems, and they are used to connect pipes and valves. They are designed to allow the pipe to rotate freely, which makes them ideal for applications where there is a need for flexibility. There are different types of swivel flanges available, and each type has its unique features and benefits. In this article, we will discuss the different types of swivel flanges and their uses.

Carbon steel swivel flange: This type of flange is made from carbon steel and is commonly used in low-pressure applications. It has a rotating flange that allows for easy alignment of the bolt holes during installation.
Stainless steel swivel flange: This type of flange is made from stainless steel and is commonly used in high-pressure and high-temperature applications. It has a rotating flange that allows for easy alignment of the bolt holes during installation.
Slip-on swivel flange: This type of flange is designed to slip over the end of a pipe and is secured in place with a fillet weld. It has a rotating flange that allows for easy alignment of the bolt holes during installation.
Weld neck swivel flange: This type of flange is designed to be welded directly to the pipe and has a long tapered neck that provides a smooth transition from the pipe to the flange. It has a rotating flange that allows for easy alignment of the bolt holes during installation.
The main differences between these types of swivel flanges are the materials they are made from, their intended applications, and their methods of attachment to the pipe. Carbon steel swivel flanges are used in low-pressure applications, while stainless steel swivel flanges are used in high-pressure and high-temperature applications. Slip-on swivel flanges are designed to slip over the end of a pipe, while weld-neck swivel flanges are designed to be welded directly to the pipe.

In conclusion, swivel flanges are an essential component in piping systems, and there are different types of swivel flanges available. Each type has its unique features and benefits, and it is important to choose the right type of swivel flange for your application. Whether you need a swivel flange for high-pressure applications or low-pressure applications, there is a swivel flange that will meet your needs.
