Due to its robust performance, Super Duplex Steel 2507 flanges are used in various industries, including:
Understanding the pricing of Super Duplex Steel 2507 flanges is crucial for several reasons:
Several factors can affect the pricing of these flanges, including:
By understanding these factors, buyers can make more informed purchasing decisions and potentially find opportunities for cost savings.
Weld neck flanges are designed for welding to the end of a pipe, creating a strong and durable connection. The long tapered hub reinforces the flange, reducing stress and making these flanges ideal for systems that handle high pressure and high temperatures, such as oil and gas pipelines.
Slip on flanges are slipped over the pipe end and then welded in place. They are easier to install than weld neck flanges and are suitable for lower pressure applications. These flanges are often used in systems where there is a low risk of leakage and where frequent disassembly is required, such as water supply systems.
Socket weld flanges have a socket into which the pipe is inserted before being welded. They are used for smaller pipe sizes and provide a smooth bore for better flow. Known for their strength and resistance to corrosion, these flanges are perfect for high-pressure systems in chemical and petrochemical industries.
Threaded flanges feature matching threads that connect without the need for welding. They are ideal for low-pressure applications where welding isn’t feasible. These flanges are perfect for systems that require frequent dismantling for inspection or maintenance, such as plumbing and fire protection systems.
Blind flanges are used to seal the end of a pipe system and have no center hole. They are used to isolate or terminate piping systems, providing secure closures in high-pressure applications like pressure vessels.
Lap joint flanges consist of a stub end and a lap joint flange. They are used where frequent disassembly is needed. The rotating flange makes it easier to align the bolt holes during installation, making them ideal for maintenance-intensive systems like those in food processing.
Spectacle blind flanges combine a blind flange and a spool piece, allowing for easy inspection and maintenance of the system. They feature a solid plate and a ring plate connected by a tie bar, enabling easy switching between open and closed positions.
Reducing flanges connect pipes of different diameters, ensuring smooth fluid flow. They are particularly useful in systems that require a transition in pipe size due to space constraints or design needs, such as HVAC systems.
Tongue and groove flanges have a tongue and groove joint that provides a secure, leak-resistant connection. They are used in high-pressure and high-temperature applications where a tight seal is crucial, such as steam lines and high-pressure gas distribution systems.
