Alloy steel flanges come in a variety of types and designs to meet the specific requirements of different applications. Some of the most common varieties of alloy steel flanges include:
- Weld Neck Flanges: These flanges have a long tapered hub and are designed for high pressure applications. They are the best choice for critical applications that require high strength and toughness.
- Slip-On Flanges: These flanges slide over the pipe and are welded in place. They are cost-effective and easy to install, making them popular in low-pressure applications.
- Socket Weld Flanges: These flanges have a socket-like connection for the pipe to fit into, providing a strong and leak-proof joint. They are commonly used in high-pressure applications.
- Blind Flanges: These flanges are used to close the end of a pipe or pressure vessel. They are typically used in applications where inspection or maintenance is required on a regular basis.
- Lap Joint Flanges: These flanges are used in applications where frequent dismantling is required. They are designed to slide over the pipe and are secured in place with a lap joint.
- Threaded Flanges: These flanges have threads on the inner diameter that allow them to be screwed onto a pipe. They are commonly used in low-pressure applications.
- Spectacle Blinds: These flanges are used to isolate sections of a piping system. They consist of two metal discs that can be rotated to block or allow flow through a pipeline.
