Description:
Plate flanges are most commonly used for joining pipes together, but they can also be used for connecting different parts of a system or even for sealing off sections where necessary. For example, plate flanges may be used to join two metal pipes together or to connect two sections of pipe with each other. Furthermore, plate flanges can also be used to seal off an area between two pieces of metal that need to remain separate from one another. Additionally, they can be used to join two plastic pipes together or even two sections of an air conditioning unit or heater.
