I already ordered some spiral wound gaskets. Now the valve supplier is telling me that I need to take my valves with smooth finish RF flange facing with Ra between 3.2 and 6.3 micro-m. Even if I specified serrated spiral RF flange face with Ra between 3.2 and 6.3 micro-m.
We have experience in installation of spiral wound gaskets with RF serrated face.
Installation of RF smooth finish with spiral wound gaskets may be a source of leakage.
I haven't found the answer on WWW so maybe here.
