A flange is a component used to connect pipes, valves, pumps, and other equipment in piping systems, providing easy assembly, disassembly, and maintenance. Flanges are typically bolted together and sealed with gaskets to ensure a leak-proof connection.

Types of Flanges:

1. Weld Neck Flange: Designed to be welded to the pipe, providing strength and reducing stress.

2. Slip-On Flange: Slides over the pipe and is welded at both ends for a secure connection.

3. Blind Flange: Used to close off the end of a pipe or valve opening.

4. Socket Weld Flange: Used for smaller, high-pressure pipes, with the pipe inserted into the flange before welding.

5. Lap Joint Flange: Paired with a stub end for easy alignment and assembly, commonly used in systems requiring frequent disassembly.

6. Threaded Flange: Screws onto pipes with external threads, ideal for low-pressure applications or where welding isn’t feasible.

Materials: Flanges can be made from stainless steel, carbon steel, aluminum, brass, PVC, or other materials based on the application and the substances being transported.

Applications: Flanges are widely used in industrial piping, oil and gas, water treatment, chemical processing, and HVAC systems to connect equipment, isolate sections, or allow easy access for inspection and repair.
