Method and tube for lining a high pressure pipe

Abstract

The invention relates to a method for lining a high pressure pipe with a tube made from interlocking, high-tensile high performance fibers, with a plastic coating applied thereto, whereby the high performance fibers are arranged in an interwoven structure and introduced into the pipe in a state of mobility relative to each other. The introduced meshing is then pressed against the inner wall of the pipe by altering the geometrical arrangement of the high performance fibers with relation to each other and then fixed by the mutual arrangement of the high performance fibers adopted after the laying thereof. The invention further relates to a tube for lining a high-pressure pipe comprising interlocking, high-tensile high performance fibers and a plastic coating applied thereto, embodied such that the high performance fibers are arranged within the structure as a mesh and the angle of the high performance fibers may be altered in relation to the perpendicular to the tube axis before the lining, such that an enlarging of the tube in a radial direction is possible.
