Introduction to PN Flanges
PN (Pressure Nominal) flanges are a widely used type of flange in piping systems around the world. The PN designation indicates the nominal pressure rating of the flange, which helps in standardizing the connection and ensuring compatibility between different components in a piping network. These flanges are available in various sizes, materials, and types, such as weld – neck flanges, slip – on flanges, and blind flanges. They play a crucial role in connecting pipes, valves, pumps, and other equipment, providing a leak – tight and reliable joint. PN flanges are commonly made from materials like carbon steel, stainless steel, and alloy steel, and are used in industries such as oil and gas, chemical, power generation, and water treatment.
