Abstract: The present invention concerns a double-walled tank container, whereby the inner container is stored at the bottom inside the outer enclosure by a spacer consisting of several spacer pieces. The spacer provided, which is preferably placed near a front saddle ring, imparts transportation and storage stresses between the inner tank and the outer enclosure and consequently between the inner container and the frame of the tank container. The spacer can be laid out in such a way that it absorbs shocks and/or defines a hollow space. This hollow space can serve as a thermal insulation or for the installation of temperature equalization devices, mediums or a leak detector fluid.

Abstract: The present invention concerns a double-walled tank container (1, 12, 13, 14) whereby the inner container (2, 3) is stored at the bottom inside the outer enclosure (6) by a spacer consisting of several spacer pieces (16). The spacer provided, which is preferably placed near a front saddle ring (12, 13), imparts transportation and storage stresses between the inner tank (2, 3) and the outer enclosure (6) and consequently between the inner container (2, 3) and the frame (14) of the tank container. The spacer (16) can be laid out in such a way that it absorbs shocks and/or defines a hollow space (10). This hollow space can serve as a thermal insulation or for the installation of temperature equalization devices, mediums or a leak detector fluid.

Abstract: A pressure-proof tank for a transport container has an envelope formed by two or more parallel part-cylindrical envelope shells 1, the ends of which are closed by bottoms 2 formed of bottom shells 3. The transition region between the bottom and envelope shells 2, 3, is closed by curved gusset elements 5. The pressure resistance in this transition region is improved by planar rib elements 10 extending through the interior of the tank. The rib elements 10 cooperate with a tension wall 4, which divides the tank in the longitudinal direction, to reduce the effect of surges acting in the transport direction, especially when the tank is partially filled.

Abstract: For heating or cooling the content of a tank, flow paths for a temperature controlling medium are provided in the form of longitudinal channels 13 of closed hollow profile separate from the tank envelope 12. The channels 13 are connected at either end to collecting channels 14 extending in the peripheral direction of the envelope 12 to form an internally continuous channel system. This channel system may be produced separately of the tank as a generally trough shaped structure and, after the tank has been placed therein, fixed to the tank and kept in close proximity to the tank envelope 12 by an insulation 16, 17 which surrounds the overall structure.

Abstract: In a tank container, the saddle connection between the tank 16 and each container end frame 10 consists of only two structural elements of simple design, i.e. an end ring 17 which is formed by a cylindrical tubular piece and welded to an area of the tank bottom 19 remote from the axis, and a saddle ring 18 which is shaped as a profile ring and welded to the inner surface of the end frame 10. The end of the end frame 17 facing the frame and an axial flange 23 of the saddle ring 18 are welded together after any lengthwise tolerances between the tank 16 and the end frame 10 have been compensated. The peripherally continuous cylindrical end ring 17 and the peripheral continuous saddle ring 18, due to the fact that they are welded together and connected to the tank bottom 19 and the end frame 10, result in an overall torsion-resistant structure which requires no diagonal elements in the end frame even for large containers.

Abstract: For protecting tank armatures 22 against mechanical and chemical influences from the environment, an armature box 25 is provided which is screwed to the container frame 13, 17 and sealed with respect to the tank jacket 10 by means of a permanent-elastic sealing material. The armature box 25 is inserted only after the tank armatures 22 have been mounted and thus does not impede their installation. On account of its rigid connection with the container frame 13, 17, the armature box 25 has a high stiffness.
