i'm encountering a new problem now, i the Piping class given, for a 400 NB wafer check valve, the length of bolt is 330mm, bolt size is 1" and number of bolts is 16.
for the same 400NB. flange to flange connection is given as 140mm length, 1" dia, and 16 number of bolts.
the face to face length of wafer check valve is 191mm.
PDMS calcualtes as follows ,
default bolt length of 400NB flanged conn with 1 gasket = 140mm
face to face lenght of wafer check valve = 191mm
Thickness of a extra gasket = 3mm
__________
total length of bolt = 334mm
___________
so my company needs that to be 330mm, still due to lack of time we are still using old bolting method,
