Road transport is essential for the USA economy. 70% of the commodities are moved by road, 15% by train and 6% by river. Traditionally, the fuel used is diesel but due to the instability of the price of it, lately many transport companies are leaning on LNG which is not as corrosive for the engines, saves space and has a much more stable price.
LNG is obtained following a cooling process and maintained to a cryogenic temperature of -162ºC. Engines use this element as fuel after a process in which this liquid natural gas comes again to its gaseous and flammable state.
There is no doubt that the best choice for the manufacturing of this kind of systems is austenitic stainless steel, because of is reliability at cryogenic temperatures, its high mechanical properties and also high resistance to corrosion.
Chart Industries Inc is worldwide leader in the fabrication of LNG cryogenic tanks for driving systems. The stainless steel used for this application is AISI 304L manufactured and supplied by NAS (North American Stainless) which is a perfect election for this giving the maximum life cycle in varied atmospheric conditions.
