Flanges are mechanical components used to connect or join two sections of piping, tubing, or other systems together. They are widely used in various industries, including automotive, oil and gas, aerospace, plumbing, and manufacturing. Here's an overview of flanges and their applications:
Purpose: Flanges serve several purposes, including:
Connecting two sections of piping or tubing to create a leak-proof joint.
Providing a means for easy assembly and disassembly of components.
Supporting and aligning piping or tubing systems.
Allowing for the attachment of additional components, such as valves, fittings, or instruments.
Types of Flanges:
Weld Neck Flanges: These flanges have a long tapered hub that is welded to the pipe or tubing, providing strength and structural integrity. They are commonly used in high-pressure and high-temperature applications.
Slip-On Flanges: Slip-on flanges slide over the end of the pipe or tubing and are then welded in place. They are easier to install than weld neck flanges but are not as strong.
Socket Weld Flanges: Socket weld flanges have a recessed area or socket that allows the pipe or tubing to be inserted, and then the two are welded together. They are commonly used in smaller diameter piping systems.
Threaded Flanges: Threaded flanges have threads on the inner bore that allow them to be screwed onto the pipe or tubing. They are used in low-pressure and low-temperature applications.
Blind Flanges: Blind flanges are solid plates that are used to close off the end of a pipe or tubing system. They are commonly used to cap off lines or openings that are no longer in use.
Lap Joint Flanges: Lap joint flanges are used in conjunction with stub ends to create a connection that allows for easy alignment and assembly.
