Disclosed embodiments relate to devices and methods for storage and/or transport of tubular structures, such as perforating guns for use in wellbores. Some embodiments relate to modular storage containers, for example which may be height adjustable depending on the length of the tubular structure to be held therein. Some embodiments relate to mobile storage banks, which may be configured for use with the modular storage containers. In some embodiments, the storage bank may further be configured with one or more longitudinal compartments configured to hold used tool strings or portions thereof.

In a packaging for a circular insertion tool, in particular a circular saw blade, with a planar main body, which has a holding flange for fixing an associated insertion tool on the planar main body, the planar main body has a polygonal outer circumference, with a tab which is bendable in the direction of the holding flange being arranged on at least one side of the polygonal outer circumference.

A package for abrasive wheels is provided. The package comprises a base providing an inner space between a side surface, an open end having a diameter D.sub.open and a closing plane end having a diameter D.sub.closed, the inner space being adapted to contain stacked abrasive wheels having a diameter D.sub.wheel, the side surface having a projecting portion having a diameter D.sub.proj, that projects from the closing plane end; and a cover configured to couple to the base at the open end so as to close the inner space, the base and the cover insulating the abrasive wheels against atmospheric agents when coupled, the cover comprising a projection shaped to define an annular plane portion having an inner diameter D.sub.in and an outer diameter D.sub.out.
