  • Tanks are already known which are constructed at east in part above ground level for storing liquefied gases, notably liquid methane, of the type comprising at least one double wall and including an external shell having a self-supporting structure of ordinary steel or reinforced concrete, for example prestressed concrete, of
  • the original feature of this building technique consists in dissociating the two problems respectively of heat or thermal expansion and mechanical strength by providing a double vessel wherein the cold inner portion consists of the internal shell of thin, flexible sheet of noble metal ensuring the necessary fluidtightness but having practically no inherent mechanical strength, whereas the warm outer portion consists of a mechanically rigid and strong external vessel surrounding said inner shell and made of conventional material such as ordinary steel or concrete, and of which the fluid-tightness is not necessarily perfect.
  • a filling of rigid heat-insulating or like material is disposed for the multiple purposes of reducing the heat brought from the outside medium to a value corresponding to the desired evaporation rate, creating a temperature gradient suificient to make the temperature within the tank consistent with the specific conditions of use of the material stored therein, and retransmitting to said external tank or shell the hydrostatic pressure stresses exerted on the internal tank or shell.

  • the present invention is also concerned with a method of constructing the device set forth hereinabove, which method is of the type consisting in erecting firstly the aforesaid external shell constituting a self-supporting envelope on said base or basement prepared beforehand, and is characterized in that it consists in successively fastening the aforesaid prefabricated brackets on the internal face of said external shell; applying and securing the aforesaid intermediate insulation to said internal face by moulding same on site by injection moulding or by applying same by means of a spray-gun, or by assembling same in the form of prefabricated panels or blocks; prefabricating corrugated sheet metal elements having a substantially rectangular contour to constitute the aforesaid internal shell, and securing these elements to said brackets in mutually overlapping relationship by simultaneously joining and tacking said sheets and then welding same along their overlapping joints.

  • the choice of the material for constructing this external vessel is dictated by economical factors. In fact, beyond a certain storage volume or capacity, the cost of a concrete structure becomes inferior to that of the ordinary steel structure.

  • This roof 6 is advantageously of cupola or spherical cap like configuration and designed to withstand the internal pressure corresponding to the vapour pressure considered as permissible for each specific application. As a rule and for an equivalent flexibility of use of the storage tank, the greater the storage capacity, the lower this maximal vapour pressure.
