Dear all!
I have a doubt regarding if a floating roof tank must have a pressure-vacuum valve or it is not necessary. I mean, usually the roof floats on the liquid surface but if there is a very sudden temperature change or, even worse, if the roof gets blocked anyhow, how is the pressure in the tank keep under allowable limits?
Thank you for any help and sorry if the question is too obvious (I am a bit new)
