PN40DN600 type 11 (WN) thk (c2) : 54

Hi abbver98,
Thanks very much for your reply, Does PN40 DN600 has other type except type 11 thk 54? if the thk is 72mm do you know what type it is belong to? Thanks.
Does PN40 DN600 type 11: 24 whether it is my question PN40 DN200?
You mean C2 is equivalent to be for ANSI flang. so I can do according to ANSI standard? But I think there has other thk is different with C2, isn't it?

Hi Lucycn,
No, there is no equivalence between ANSI and EN flanges. The dimensin c2 or c3 designates b for ANSI.
For Integral flange (type 21) :
PN40 DN600 has thk of 72 mm (c3)
PN40 DN200 has thk of 34 mm (c3).
