Abstract
Polymer tubing, made of at least one polymer layer, has a partial section of the tubing which is corrugated and wherein the rings formed by the corrugations extend around the tube axis, with the corrugations being embodied at least partially in an oval shape or in the shape of an ellipse or in the form of a circle, which is flattened on one side.
Claims31
Polymer tubing capable of being charged with pressure, having a high degree of flexibility, high bursting pressure resistance, and a short linear extension, made of at least one polymer layer, wherein the tubing is corrugated in at least one partial section and has rings formed by the corrugations extending concentrically around the tube axis, wherein the corrugations are oval shapes, elliptical shapes or circle shapes flattened as a geometric segment on at least one side of the rings and wherein said flattened geometric segments are continuously displaced circumferentially at a defined angle which is no greater than about 180.degree. C.
A corrugated polymer tubing made of at least one polymer layer comprising a series of axially spaced rings which extend substantially entirely about the circumference of said tubing,
- a plurality of said rings having an oval or elliptical shape having a minor axis and a major axis, or circular shape with a flattened segment portion on at least one side,
- each of said rings differing from at least one adjacent neighboring ring in the orientation or location of said major and minor axes if said rings are in the shape of an oval or an ellipse, or in the location or orientation of said flattened portion if said plurality of rings are in the shape of a circle having a flattened portion on at least one side, whereby said major and minor axes or said flattened portions are spaced circumferentially and axially along said polymer tubing.
