Socket Weld
Socket Weld Flange
1. Socket weld flanges feature a socket- like recess on the inner bore for welding with pipes.
2. They are ideal for small-bore piping systems and high-pressure applications.
3. Socket weld flanges provide leak-proof connections and are easy to install and weld.
Blind
Blind Flanges
1. Blind flanges are solid disks used to block off a pipeline or to create a dead end.
2. They are commonly used for pressure testing, inspection, and maintenance of piping systems.
3. Blind flanges are available in various materials and sizes to suit different applications.
Weld-Neck
Weld-Neck Flanges
1. Weld-neck flanges feature a long-tapered neck that transitions smoothly to the pipe.
2. They provide excellent structural integrity and are suitable for high-pressure and high-temperature applications.
3. Weld-neck flanges are welded to both the pipe and the hub of the flange, ensuring a strong and reliable connection.
Slip-On
Slip-On Flanges
1. Slip-on flanges have a slightly larger bore diameter than the outer diameter of the pipe.
2. They are slipped over the pipe and then welded in place, providing easy alignment and installation.
3. Slip-on flanges are commonly used in low-pressure applications and systems with frequent assembly and disassembly.
Threaded
Threaded Flanges
1. Threaded flanges feature internal threads that allow them to be screwed onto the pipe end.
2. They are suitable for low-pressure applications and are commonly used in small-diameter piping systems.
3. Threaded flanges provide a secure and reliable connection without the need for welding.
Lap Joint
Lap Joint Flanges
1. Lap joint flanges consist of two parts: a stub end and a backing flange.
2. They The stub end is welded to the pipe, while the backing flange slides over the pipe and is free to rotate.
3. Lap joint flanges are used in systems requiring frequent dismantling or where alignment of bolt holes is critical.
Orifice
Orifice Flanges
1. Orifice flanges are designed for flow measurement applications using orifice plates.
2. They feature a small-bore hole or orifice that is positioned concentrically with the pipe bore.
3. Orifice flanges allow for accurate measurement of fluid flow rates and are commonly used in process industries.
Expander
Expander Flanges
1. Expander flanges are used to increase the bore size of a pipeline or to connect pipes of different sizes.
2. They feature a tapered inner bore that gradually expands to accommodate larger pipe diameters.
3. Expander flanges provide a smooth transition between pipe sections and minimize turbulence in the flow.
