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