Types of Alloy Steel Threaded Flanges
These flanges are easy to install and provide a secure connection for low-pressure applications. They are commonly used in small-diameter, high-pressure piping systems. They are commonly used when there is a need for future access to the pipe or for temporary closure during maintenance or repairs. These flanges are used when quick disassembly or alignment adjustments are required. They are commonly used in systems where a reduction in pipe size is required.
- Threaded Slip-On Flanges: These flanges have a bored-out inner diameter that matches the pipe's outer diameter.
- Threaded Weld Neck Flanges: Raised face slip-on flanges have a raised section around the bore, which acts as a sealing surface.
- Threaded Socket Weld Flanges: Socket weld flanges have a socket-like end that is welded to the pipe, ensuring a secure and leak-resistant connection.
- Threaded Blind Flanges: Blind flanges are solid discs used to close off or seal the end of a pipe.
- Threaded Lap Joint Flanges: Lap joint flanges consist of two separate components - a flat face flange and a stub end.
