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.

Abstract: A flexible tube for lining pipes and ducts as well as a method and an apparatus for manufacturing thereof are suggested. The flexible tube is composed of a coated fabric of high resilient warp threads as well as woof threads having lower elasticity. With the flexible tube thus suggested, strong curvatures or angles being present in the pipes can be lined without wrinkles and all-over for the first time.This is enabled in that the high resilient warp threads are stabilized by covering yarn upon straight pipe portions and hence comprise a limited linear extension such that the flexible tube can be placed inside the pipe in quality.In the curved pipe portions the high elasticity of the basic warp thread is activated by a force increase during passing through these portions by compensating the forces of the covering yarn, such that the flexible tube closely fits to the inner pipe wall, all-over and without any wrinkles in these regions.

Abstract: It is described a method for lining a pipe or a duct through an internal lining of a plastic coated flexible fabric tube adhering to the inner wall of the pipe by means of an adhesive. This method stands for the following steps:filling a metered amount of adhesive into said flexible fabric tube in a uniform distribution over the flexible tube length,introducing said flexible fabric tube into the pipe, wherein one end of said flexible tube is fastened to the rear pipe end with respect to the moving direction, and the flexible tube using turning up is introduced into said pipe, andgenerating an internal pressure inside said introduced flexible fabric tube by means of supplied water for pressing said flexible tube against the inner wall of said pipe until the adhesive between said flexible tube and the inner wall of said pipe is cured. Here, the water is heated and cooled in controlled manner depending on the temperature values measured inside and outside the pipe for accelerating the curing operation.
