FIELD: constructional engineering.
SUBSTANCE: invention refers to manufacture of pipes. The pipe or capacity has layered vessel made of composite material based on organic and/or inorganic binder containing main wall of certain diameter and subsequent layers consisting of coil-shaped hollow stiffening rings separated by solid partitionwall along pipe or capacity axis. Coil of the first row rings is wound on solid partitionwall separating it from the previous layer left to right, and of the second row - right to left to form generally cellular structure of the case.
EFFECT: increased stiffening rings of pipe or capacity at insignificantly increased weight.
