METHOD OF MANUFACTURE OF THE PIPE Russian patent published in 2006 - IPC B29D23/00 B29K101/00 

FIELD: methods of manufacture of the pipes out of the composites.

SUBSTANCE: the invention is pertaining to the method of manufacture of the pipes out of the composites. The method of manufacture of the pipes includes the screw-type coiling of the belt composite-fibrous material and fastening their butts together. The method provides, that the solidified composite-fibrous material is rolled in a pipe without application of the mandrel with simultaneous fastening its butts together with the help of the lengthened H-shaped locking member with the binding composition. The method ensures the capability to maintain the shape at coiling without usage of the mandrel and fixation of the shape of the product without the process of polymerization, that allows to expand the technological capabilities of the method.

EFFECT: the invention ensures the capability to maintain the shape at coiling without usage of the mandrel and fixation of the shape of the product without the process of polymerization, that allows to extend the technological capabilities of the method.
