FIELD: machine building.
SUBSTANCE: tube (10) and a method of making such a tube, wherein tube (10) is made in the form of a composite film structure obtained by co-extrusion of multiple layers bonded together to provide a solid structure. Layers include inner layer (11), intermediate layer (12) and outer layer (13). Intermediate layer (12) is made of material compatible with two adjacent layers (11, 13), between which said layer is located, wherein intermediate layer (12) provides connection between two layers (11, 13) to provide tube (10) in form of a solid structure. External surface (15) of tube (10) is not necessarily processed, or modified, or has coating usually for binding with other substance, such as resin binder. Described also is a hollow structure in the form of a tubular element made in the form of a pipe and made using tube (10).
EFFECT: technical result is obtaining simple but highly efficient design for mass production of extruded tube.
