METHOD FOR MANUFACTURING OF PIPE FROM FLAKY COMPOSITE MATERIAL AND PIPE MADE OF FLAKY COMPOSITE MATERIAL Russian patent published in 2010 - IPC B29C53/60 F16L9/12 F41F3/42 

FIELD: technological processes.

SUBSTANCE: inventions relate to pipe of flaky composite material and method of its manufacturing. Method for manufacturing of pipe includes winding of inner glass plastic layer onto mandrel, bonding of intermediate foam plastic layer and winding of ribs and outer layer of glass plastic. In intermediate foam plastic layer there are circular grooves arranged for location of ribs. Ribs and outer layer is wound in a single technological operation by bundle of cross threads. Bundles are equipped with longitudinal threads, using method of cross-fibred longitudinal-transverse winding. At the same time longitudinal threads are bent as bundle changes from winding of external layer to winding of ribs and back with filling of each groove by mentioned bundle till ribs are formed.

EFFECT: improved manufacturability and reliability of glass plastic pipes operation.
