Another key benefit of slip-on flanges is their compatibility with various pipe types. The slip-on design allows the flange to fit over pipes of different diameters, making them highly adaptable. Whether you're working with welded pipes, threaded pipes, or other types of pipe connections, a slip-on flange can be easily installed without modification. This compatibility further adds to their appeal, as they eliminate the need for customized parts or complex fittings.
How Do Slip-On Flanges Work?
To understand the role of a Slip-On Flange, it's important to know how it works within a pipeline system. A slip-on flange is typically installed in the following manner:
Pipe Preparation: The first step is to prepare the pipe that the flange will be attached to. The pipe is cut to the correct length, and the end is usually beveled to allow for easier welding.
Flange Placement: The slip-on flange is then slid over the pipe, aligning the hole of the flange with the pipe. The flange fits loosely, but once welded, it provides a secure connection.
Welding the Flange: After positioning the flange, it is welded both inside and outside. The welding creates a permanent bond, preventing leakage and ensuring a strong connection between the flange and the pipe.
Inspection and Testing: After installation, the system is typically tested to ensure there are no leaks or issues with the connection. This step is crucial for ensuring the integrity and safety of the piping system.
The Difference Between Slip-On and Other Types of Flanges
Slip-on flanges stand apart from other flange types, such as weld neck, blind, and threaded flanges, in several important ways.
Weld Neck Flanges: Weld neck flanges have a long neck that allows for a more durable and stronger joint, making them ideal for high-pressure applications. However, they require more precise welding and fitting, which can make installation more complex and time-consuming compared to Slip-On Flanges.
Blind Flanges: Blind flanges are used to seal the end of a piping system. They do not have an opening and are typically welded or bolted to the pipe. Although blind flanges can provide a secure closure, they are not intended for connections between pipes, making them unsuitable for many quick installation applications.
Threaded Flanges: Threaded flanges are flanges that are connected to pipes through threaded connections. These flanges are ideal for systems where welding may not be an option. However, they are less common for high-pressure systems and are not as simple or quick to install as slip-on flanges.
