Dn50 pn16什麼意思

"DN50 PN16" is a designation used for pipes, fittings, and valves in the field of fluid handling, particularly in industrial applications. Here's what each part of the designation means:

• DN (or DN50): This stands for "diameter nominal" and is a standard size designation used in metric pipe systems. The number (50 in this case) indicates the approximate inside diameter in millimeters. A DN50 pipe has an inside diameter of approximately 50 mm.

• PN (or PN16): This stands for "pressure nominal" and indicates the pressure rating of the pipe, fitting, or valve in bar (or kilopascals, kPa). The number (16 in this case) corresponds to the minimum burst pressure, which is the pressure at which the pipe or fitting might rupture. In the case of PN16, the pipe or fitting is designed to withstand a pressure of at least 16 bars (1600 kPa).

So, a DN50 PN16 pipe, fitting, or valve is a standard size (DN50) with a pressure rating of PN16. This information is important for selecting the appropriate components for a system that will handle fluids under specific pressure conditions.
