A Plate Flange is a flat, circular flange with no raised face or protrusions. They are often used in low-pressure applications, such as plumbing and water supply systems.
A Reducing Flange is designed to connect pipes of different diameters. It has a larger bore on one end and a smaller bore on the other, allowing for the transition between pipe sizes.
A Ring Type Joint Flange, commonly known as RTJ Flange, is designed with a groove and ring gasket to create a metal-to-metal, high-pressure, and high-temperature seal. It’s widely used in demanding applications.
A Socket Weld Flange, abbreviated as SWRF, is a type of flange that is welded directly to the pipe’s end. It has a socket-like connection for the pipe to fit into, providing a strong and leak-resistant joint.
A Spectacle Blind Flange is a special type of flange used to temporarily or permanently block off a pipe. It consists of two metal discs connected by a handle, allowing one disc to be rotated to block the flow.
A Spool Flange is a short, straight piece of pipe with flanges on both ends. It is used to connect different components of a pipeline, such as valves, pumps, or instruments, allowing for easy installation and removal.
A Studding Outlet Flange is designed to provide a reinforced threaded connection point on a pipeline for bolting other components, such as valves or equipment.
A Swivel Ring Flange is designed to allow for the rotation of flange faces independently, which can help accommodate misalignment or movement in piping systems.
A Threaded Flange is a type of flange with internal threads designed to screw onto the external threads of a pipe or fitting, creating a secure and sealed connection without welding.
A Tongue and Groove Flange features a protruding “tongue” on one flange face and a matching “groove” on the other. When two flanges are bolted together, the tongue fits into the groove, providing alignment and a secure seal.
A Weld Neck Flange, abbreviated as WNRF (Weld Neck Raised Face) or WNFF (Weld Neck Flat Face), is a type of flange designed for high-pressure and critical applications. It has a long neck that is welded to the pipe, providing strength and better flow control.
A Weldoflange or Weldolet Flange is a combination of a flange and a branch connection, allowing a smaller pipe or tube to be connected to a larger one through a weld. They are commonly used in piping systems for branch connections.
A Wire Seal Flange features a groove where a wire or seal can be placed to create a secure, leak-resistant connection. It is commonly used in applications where sealing integrity is crucial.
An Expander Flange, also known as a “Van Stone” flange, is used to transition between two different pipe sizes. It has a larger diameter than the pipe it connects to, gradually expanding the bore.
