Types of Alloy Steel Slip On Flanges
This is the most common type of weld neck flange. It features a tapered hub and a neck that is welded
to the pipe, providing a smooth transition from the flange to the pipe. Standard weld neck flanges
are suitable for high-pressure and high-temperature applications. Long weld neck flanges have an
extended neck length, which provides additional reinforcement and allows for easier alignment of the
pipe.
- Standard Slip-On Flanges: These flanges have a flat face and are the most common type
used in low-pressure applications.
- Raised Face Slip-On Flanges: Raised face slip-on flanges have a raised section around the
bore, which acts as a sealing surface.
- Ring Type Joint (RTJ) Slip-On Flanges: RTJ slip-on flanges are designed with a groove to
accommodate a metal ring gasket.
- Large Diameter Slip-On Flanges: These flanges are specifically designed for larger pipe
sizes and higher flow rates.
- Customized Slip-On Flanges: Manufacturers can also provide customized slip-on Alloy Steel
flanges to meet specific requirements.
Features of Alloy Steel Slip On Flanges
- Slip-on flanges have a design that allows for easy alignment and installation. They slide over
the pipe and are then welded in place, providing a secure and leak-free connection.
- slip-on Alloy Steel flanges are suitable for a wide range of applications, including
low-pressure and low-temperature systems.
- Slip-on flanges are generally more cost-effective compared to other types of flanges.
- Slip-on flanges provide a secure connection by welding the flange to the pipe.
- Slip-on flanges have a slim profile and take up less space compared to other types of flanges.
