I am a graduate student in the Dept. of Mechanical Engineering at West Virginia University. As a part of my research, I’m doing a case study of design of a Cryogenic Pressure Vessel. I’m facing a little difficulty in the process, and would be very grateful to you if you could give me some information, particularly about how the inner vessel is suspended in the outer vessel.

February 23, 2009Most manufactures will be reluctant to share this type of information since its considered to be proprietary information. It also varies by horizontal orientation or vertical orientation. A vessel meant to travel over the road would also have a different type of support.
The most common vessel is a stationary vertically oriented vessel. Most manufacturers will suspend the inner vessel within the outer vessel using 3 or more long thin straps that run lengthwise with the axis of the tank. One end of the strap will be welded to the inner vessel while the other would be welded to the outer. The best description is an upside down tripod.
The de facto standard reference book for the industry is the one at the link below which you might be able to find at an engineering library.
