Thank you. I assumed 660 deg for melting point of aluminium. I wondered if the 649 deg was somehow chosen for this reason? I am aware we are very close to the melting point but wondered if the multiple layers of separating layers would keep the insulation in place and reduce heat transfer to the...
I would be very grateful if someone could tell me if they have a value for "U" as described within CGA S1.2 "Pressure relief device standards part 2 - Cargo and portable tanks for compressed gases" cl 6.3.3. for super insulated cryogenic vessels. The insulation system consists of approx 35...
