What is an ASME B16 48 flange?
This standard covers the pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing of service piping blanks in sizes NPS 1/2 to NPS 24 for installation between ASME B16. 5 flanges in pressure classes 150, 300, 600, 900, 1500 and 2500.
DN80 indicates the nominal diameter of the flange, that is, the inner diameter of the pipe is approximately 80 mm (3.15 inches).
DN80 Asme B16.48 Slip On Flange refers to the carbon steel flange slip in the ASME B16.48 standard with a nominal diameter of 80mm. This kind of flange tile is made by forging process and has good mechanical properties and corrosion resistance. It is usually used for pipeline connections in petroleum, chemical, pharmaceutical and other industrial fields.
