Question:

Who can tell me what "DN" and "PN" mean in flanges, and what does PN16 stand for?

Who can tell me what "DN" and "PN" mean in flanges, and what does PN16 stand for?

Answer:

with 32 DN30. diameter pipe pipe with pipe ----------PN----- Phi 38 maximum value, the unit is "MPa, 1 MPa and cm - equivalent to 10KgPN16 refers to the pipe and the flange matched bearing pressure approximately 12 MPa. The equivalent of 120Kg - and cm
DN----- through the flange -- such as pressure DN15. with Phi 18 DN25.
