A REVERSIBLE LINNING TUBE FOR REPAIRING AN EXISTING PIPELINE

摘要

There is provided a reversible lining tube 101 for repairing an existing pipeline 109. Such a lining tube 101 is reversible into the existing pipeline 109 so that its initial inner surface becomes outer surface which adheres to the internal surface of the pipeline 109. In detail, the reversible lining tube 101 includes an elastomer layer 104 and a thread-knitted layer 103, prior to reversal into the existing pipeline 109 the elastomer layer 104 is an outer layer and the tread-knitted layer is an inner layer, upon reversal into the existing pipeline 109 the elastomer layer 104 becomes an inner layer and the thread-knitted layer becomes an outer layer which adheres to the internal surface of the existing pipeline 109.
