Tank wagons for transportation of liquefied gases, tanks for transportation of liquefied gases

摘要

Technical solutions related to the field of specialized vehicles used for transportation, preferably by rail liquefied gas for various purposes, such as propane, butane, and others. The technical result of this decision is to ensure reliability and durability of these devices by integrating welds layout of the tank Valley not leading, in the case of dynamic effects, to the integrity of the tank by welding seams. Part tank cars, this is achieved by the fact that the car tank for transportation of liquefied gases includes mounted on wheeled bogie frame on which is secured having a hatch and clans tank formed by interconnected by weld seams made with the inner and the outer side of the annular joint space edges, at least four sequentially mounted cylindrical shells rolled from sheet metal, the edges of which are welded end-punched from a sheet metal bottom, while the ness sheet mantle metal equal to the sheet thickness of the bottom metal, each milled sheet of metal is coupled to shroud by a longitudinal weld seam disposed at the end shroud in the upper parts thereof with an offset along the circumference of their surface, preferably by an equal amount not less than 200 mm, in the opposite side relative to the longitudinal vertical plane of symmetry of the tank, and the longitudinal welded seams on at least two adjacent ferrules, located between the end shells, are oriented in a counter opolozhnye sides with; offset circumferentially with respect to the length of the horizontal passing through the central horizontal plane of the longitudinal axis of the tank, preferably by an equal amount not less than 200 mm. In this tank may be made of an even number of cylindrical shells rolled and may be provided with an additional hatch located on the shell, which has no main hatch. In the tank, this is achieved in that the tank for transportation of liquefied gases has hatch and the valve and formed by interconnected by weld seams made with the inner and the outer side of the annular joint space edges, at least four serially fitted cylindrical rolled from a sheet shells metal to the end edges of which are welded to the bottom of the punched metal sheet, the metal sheet thickness of the sleeve is equal to the thickness of the bottom metal sheet, each milled sheet metal with of the connections in the shroud by means of a longitudinal weld seam located on the end shroud in the upper parts thereof with an offset along the circumference of their surface, preferably by an equal amount not less than 200 mm, in opposite directions relative to the longitudinal vertical plane of the tank of symmetry and the longitudinal welds on, at least two adjacent ferrules, located between the end shells, are oriented in opposite sides at offset circumferentially with respect to the length passing through Tsentral nuyu horizontal longitudinal horizontal axis of the tank, preferably by an equal amount not less than 200 mm. 2 bp 2 and ZP f ly-4-yl.
