  Weld Neck Flanges
Application: These are mainly used on heat coupling of pipes in the most difficult cases, i.e., when bending stress on the coupling, due to expansion of section or to other forces, is foreseen.
  Long Weld Neck Flanges
Application: Long Weld Neck Raised Face (LWNRF) flanges are similar to a standard Welding Neck flange, but the "Neck" is considerably longer. This type is often used as a nozzle for a barrel or column. In addition, there are the type LWN Heavy Barrel (HB) and the Equal LWN Barrel (E); they have a different shape and a thicker "Wall".
  Slip on Flanges
Application: Used in quick assembly to save the cost, these are also used in less strict requirements in terms of length of pipe section.
  Socket Welding Flanges
Application: Used in quick assembly to save the cost, these are also used in less strict requirements in terms of length of pipe section.

  Lap joint Flanges
Application: These are primarily used when quick assembly and disassembly of pipeline section is required under limited working pressure.
  Threaded Flanges
Application: These flanges are used in special requirements to work under high temperature and pressure, making sure no welding joint is made at the assembly.
  Blind Flanges
Application: A blind flange is a solid disk used to block off a pipeline or to create a stop. The blind flange is machined in the same manner as a regular flange with the mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that a blind flange has no opening to allow fluid to pass through. The blind flange can be inserted between two open flanges and used to block off the flow of liquid through a pipeline.
