Abstract

The invention relates to a pipeline lining material for use for at least two, preferably three, predefined pipeline nominal widths, comprising an elastic round knitted material, which is knitted under pretension so as to contract to an untensioned diameter of +/−10% of the smallest predefined pipeline nominal width after being knitted, and comprising an elastically flexible film tube arranged around the round knitted material. The pipe lining material can be expanded by at least 50% in the transverse direction under a pressure of maximally 0.7 bar, at which the untensioned round knitted material maximally has a diameter that is reduced by 55% compared to the round knitted material under pretension.
