cvatanks.com. There is a gentleman by the name of Keith Hall that can answer just about any question you have about Cryogenics. I'm not sure if the website talks about them, but he is a world of knowledge on this. I worked for a company that manufatured Cryogenic vessels as a Quality Control Manager for 5 years, if there is anything in particular that you are inquiring about maybe I can help. If not Keith for sure can.

Chicago Bridge and Iron (CBI) is were I found info on LNG cryrogenics. They were the manufacter of the LNG Plant that  I have recently completed a project for. The plant was dated from the early 1970's. There was a lot of info there- Ted
