To connect diferent pipes and valves to achieve different functions, there are 6 types of common flanges as below:
Weldneck flange
Threaded Flanges
Socket-Weld Flanges
Slip-On Flanges
Lap Joint Flanges
Blind Flanges
Nominal pressure PN is a numeric pressure-related marker code, a convenient round integer for reference.
All pipe attachments of the same nominal common diameter represented by the same nominal pressure PN value have the same connection size adapted to the end connection type.
The PN16 flange approximation is understood as a pressure resistance of 1.6Mpa.
The flanges (PN10 and PN16) can be made of carbon steel, stainless steel as well as alloy steel.
The PN10 flanges pressure is 10kgs
The PN16 flanges pressure is 16kgs, which is higher than the PN10 flange.

Threaded(DIN2565 2566 2567)
Slip On(DIN86029 86030)
PN16 flange connecting end pressure for PN16 pipeline systems, higher than PN10 flange.
They both belong to DIN/BS/UNI standards.
