For externally mounted centrifugal cryogenic pumps, manufacturers expect mechanical seals to last for at least 1,000 hours if run under recommended conditions. Given the hassle and expense to make repairs, and the associated downtime, leaky...
Part one of A Cryogenic Transport Trailer Buyer’s Guide in last month’s issue of gasworld discussed important pre-purchase considerations such as: tare weight versus capacity, vacuum insulation integrity, trailer design specifications, nominal evaporation rate (NER)...
Are you a small industrial gas distributor and cannot afford to have a cryogenic fleet engineer on staff? What do you need to know when purchasing a cryogenic transport trailer?
There is really no such thing as a perfect vacuum – just varying degrees of very low pressure. Even in deep interstellar space, the closest there is to a perfect vacuum, there are still a...
