Flanges are external or internal ridges, rims, or lips that are used to provide strength or attachment points in various mechanical assemblies. They are commonly found in piping systems, where they serve several important functions:

  1. Joining: Flanges are used to connect pipes, valves, pumps, and other equipment together. They provide a convenient and secure method for joining components, allowing for easy assembly and disassembly when maintenance or repairs are needed.
  2. Sealing: Flanges often incorporate gaskets between mating surfaces to create a tight seal, preventing leaks of liquids or gases from the system.
  3. Support: Flanges can provide structural support and reinforcement for pipes, particularly at junctions or points where stress concentrations occur.
  4. Alignment: Flanges help to align and position components accurately, ensuring proper operation and minimizing wear and tear on the system.

Flanges come in various shapes, sizes, and materials to suit different applications and operating conditions. Common types include welding neck, slip-on, socket weld, threaded, and blind flanges. They are widely used in industries such as oil and gas, chemical processing, power generation, and manufacturing.
