FIELD: machine building.
SUBSTANCE: group of inventions relates to pipeline transport. Proposed pipe (10) comprises at least one tubular sheath (20) delimiting passage (11) for the circulation of the abrasive material, at least one tensile armour layer (34, 36) arranged externally with respect to tubular sheath (20) and comprising a plurality of filiform armour elements (44). Said pipe also comprises internal protective layer (40) arranged inside tubular sheath (20) in circulation passage (11), comprising elastomer matrix (50) and longitudinal reinforcing assembly (52) embedded in matrix (50). Method of manufacturing such a pipe (10) and the use thereof for transporting an abrasive material are also proposed.
EFFECT: group of inventions can be used for transportation of an abrasive material collected on the bottom of the body of water through a body of water.
