  • tanks for transporting and storage of liquids are known, caged in metal cages .
  • the metal cage serves to protect the tank and to contain the deformations of the shape of the tank itsel f .
  • the tanks in fact have a parallelepiped shape which on one hand allows for rapid stacking, but on the other hand does not allow for balanced distribution of stresses on the surface of the tank .
  • the metal cage is thus necessary to reinforce the shape of the tank and contain the deformation thereof .
  • caged tanks comprising a bottom portion comprising a recess towards the inside of a volume of the tank .
  • the recess comprises an inner wall where a through hole is drilled between the outside and the inside of the volume of the tank to which a tap is applied to extract the fluid contained in the tank .
  • the wall of the tank which is immediately above the recess for the tap is particularly subj ected to deformations , in particular to bulging, because no vertical tubular element of the metal cage can pass in front of the tap, and thus no vertical tubular element passes in front of this portion of the wall .
  • the part of the wall of the tank immediately above the recess for the tap comprises a top recess that partially limits the bulging deformation of the wall of the tank, but often deformations of the wall occur that are so large as to cause breakages in this part of the wall , resulting in the dangerous release of the fluid contained in the tank .
  • An obj ect of the present invention is to make a tank for transporting and storage of liquids that is reinforced and reduces the bulging deformation of the wall arranged above the recess designed for the tap .
  • such obj ect is achieved with a tank for transporting and storage of liquids according to claim 1 .
