Fluid transfer pipe with corrugated portion(s) and method for manufacturing same

The pipe has a monolayer or multilayer corrugated bendable or bend portion provided with radial reliefs, where each relief includes front and rear frontal areas connected together by a circumferential intermediate area. Each frontal area includes a polygonal contour (15) e.g. square shape contour, d...

Beschreibung
Zusammenfassung:	The pipe has a monolayer or multilayer corrugated bendable or bend portion provided with radial reliefs, where each relief includes front and rear frontal areas connected together by a circumferential intermediate area. Each frontal area includes a polygonal contour (15) e.g. square shape contour, defining straight sections i.e. flat sides, connected together via round sections. The frontal areas are joined in the round sections in the intermediate area by forming discontinuous convex bulbs (19) for each relief, where the bulbs are in circular arc in circumferential and axial directions. An independent claim is also included for a method for manufacturing a pipe.
