Is anybody aware of DIN Flange drilling Template Spec for PN20 and PN50 Flanges? DIN 1092-1 includes all but PN20 and PN50. I'm Designing Valves to meet ASME Class 150, 300 and 600 and they must also meet equivalent PN20, PN50 and PN100. PN100 dimensions in DIN 1092-1 are not the same as ASME...
What Standard contains Flange Dimensions for PN20 (equivalent to ASME 150 class) and PN50 (equivalent to ASME 300 Class)? I have a copy of BS EN 1092-1 but it does not include PN20 or 50.
Thanks
ASME Section VIII DIV 1 Appendix Y states that the rules apply to flat Face, Identical and Non-Identical Flange Pairs where uniform metal to metal contact occurs outside bolt circle. The rules apply for negligible gasket loads (ie. Pressure Energized O-ring Body Seal) HG=0. In addition, Section...
