    Plastic or elastomeric shells may be placed between pairs of layers of filaments or between layers of one pair.
    The coating 7 may be made of stapled thin strip material that provides crushing strength and resistance to external pressure.
    Examples of the pipelines according to the invention are presented in table.
    The proposed pipeline, when creating significant internal pressure on the order of tens of MPa, provides only minor or zero axial deformation, and can also have a shortening.
