Abstract:
1. A method of lining a host pipe having a cylindrical cross-section and connecting the lined pipe with an adjacent pipe, comprising the steps of: (a) securing a split sleeve to an end of the host pipe to form a generally axial cylindrical extension thereof, the split sleeve including longitudinally extending sleeve halves; (b) providing a liner having a non-cylindrical cross-section within the host pipe and the split sleeve; (c) reforming the non-cylindrical liner within the host pipe and the split sleeve to generally conform the liner to the inner diameters of the cylindrical host pipe and the split sleeve; (d) removing the split sleeve halves from about a reformed end portion of the liner within the split sleeve; (e) cutting the liner end portion to a predetermined length; (f) providing a flange on the end of the reformed cut liner end portion; (g) securing the split sleeve about the reformed cut liner end portion; and (h) securing the adjacent pipe or an extension of the adjacent pipe and the split sleeve to one another at an end of the split sleeve remote from the end of the host pipe and with the liner end portion flange between the split sleeve and the adjacent pipe.
