A tank for the storage of liquid or gaseous substances with a fiber-reinforced plastic sheathing, which limits at least one interior space for holding the materials to be stored. At least one circumferential section of the fiber-reinforced plastic sheathing comprises an evacuable sandwich structure, which completely encloses the circumferential section. As a result, the tank has a low weight with a high thermal insulation capacity. Furthermore, a reliable explosion protection of the tank is provided. Furthermore, a method for manufacturing a tank for the storage of liquid or gaseous substances is provided.

In an aircraft water tank, a mouthpiece is attached to an inner liner, and an overflowing adhesive is received in an annular missing portion provided to an expanded portion of the mouthpiece through the gap between a skirt portion and the inner liner. Further, a sealant fills the part of the annular missing portion, which is exposed from an end of a plate portion for the expanded portion.

A quasi-cylindrical cargo container is formed of a plurality of rigid, curved panels together forming first and second semi-cylindrical shells, and a plurality of rigid, flat extension panels bridging the first and second semi-cylindrical shells. A method of manufacturing the container includes forming the first and second semi-cylindrical shell from the curved panels, forming the quasi-cylindrical shell from the first and second semi-cylindrical shells and the flat extension panels, forming collars conformably encompassing the quasi-cylindrical shell, constricting the collars to compress joints formed at abutting edges of pairs of adjacent panels, rolling the shell and collars sequentially to bring the joints to a lower position, welding inside seams of the joints when at the lower position, removing the collars, rolling the shell sequentially to bring the joints to an upper position, and welding outside seams of the joints when at the upper position.

A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements. Before heating of the elements, the flanges are gripped by a clamp which applies a resilient force which, during welding, causes the flanges to move toward each other and thereby a good weld joint is formed.

A tank (e.g., an underground storage tank), and manufacturing methods therefore, may include a tank body having an exterior surface. A component is mounted on at least a non-planar portion of the exterior surface of the tank body using an adhesive (e.g., an MMA adhesive). For example, the component may be positioned on the non-planar portion of the exterior surface of the tank body after application of adhesive and pressure may be applied to maintain the position of the component on the non-planar portion of the exterior surface of the tank body as the adhesive is cured. The pressure may be removed upon curing of the adhesive and formation of a structural bond may occur at the adhesive interface between the mounting surface of the component and the non-planar portion of the exterior surface of the tank body.

The invention relates to an assembly (10) of a tank container (20), an inliner (40) and a connection unit (60) for the transport and/or storage of a liquid. The inliner is present in the tank container and the outlet of the inliner is connected to the drain hole (25) of the tank container. A connection unit is present that secures the connection of both outlets and at the same time provides a liquid tight and an air tight connection with an external unit for the delivery or discharge of the liquid contents.
