This month, gasworld takes a look at the many ways cryogens are used in manufacturing and processing. Here we examine shrink fitting, a unique way of applying very cold temperatures to manipulate metal.
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 few hydrogen molecules to be found per cubic meter.
Month on month the gasworld website continues to be the primary portal for information, on a global scale, about our industry - be it through the provision of news and features, or information in the expansive company directory section. Launched in 2004, it is the only independent online news provider and information portal for the global industrial gas community and the larger end-user markets. The website also now incorporates news for gasworld US and Specialty Gas Report.
