Hello pals,
Does somebody know when and why a double Split backing ring shall be used? I know that ASME, app II shows up how to perform this calculation, but I can not find the reason to use a double split backing ring instead a simple split backing ring. Any suggestions, theories…?
Thanks!
According to ASME II part D, note G5 is not recommended for bolted connections due to higher deformation at gasket seating. ASME VIII appendix 2-14 provides a method of checking flange rigidity, so the question is: Can I use material within note G5 if I check its rigidity according to ASME VIII...
