Abstract
The method involves a pipe bundle arrangement, each bundle having a length, a width and a depth and being a shape bundle having a rectangular or a round bundle having a hexagonal cross-section. Each bundle has a type, each type having predetermined ranges of length and width, the bundle being assigned to that type in respect of which the length and width falls within the predetermined ranges. In the arrangement: no stack exceeds a predetermined height; no round bundle has stacked thereupon a shape bundle nor a round bundle of another type; the predetermined length range of each bundle in a stack is common; the predetermined width range of each shape bundle in a stack is common; and in no stack is a round bundle stacked upon a shape bundle wherein the predetermined width range of the round bundle is greater than the predetermined width range of the shape bundle.
