Fives' cold box casings consist of a carbon steel self-supporting structure closed by welded sheets of carbon steel. The box - fitted with a nitrogen purge system and pressure relief devices - also contains stainless steel beams that support the enclosed equipment. As a cold box is usually transported horizontally (as opposed to its vertical operating position), temporary support material is added to protect the equipment during the transportation and erection phases.
