    摘要: There is provided a reversible lining tube 20 for repairing an existing pipelinel. Such a lining tube 20 is reversible into the existing pipeline 1 so that its initial inner surface 20b becomes outer surface 20a which adheres to the internal surface of the pipeline 1. In detail, the reversible lining tube includes an elastomer layer 20a and a flock layer 20b, prior to reversal into the existing pipeline 1 the elastomer layer 20a is an outer layer and the flock layer 20b is an inner layer, upon reversal into the existing pipeline 1 the elastomer layer becomes an inner layer and the flock layer becomes an outer layer which adheres to the internal surface of the existing pipeline 1. Alternative embodiments utilise a thread-knitted layer in place of the said flock layer.

    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.

    摘要: There are provided methods of lining the internal surface of a pipe (7), which includes first inserting two lining pigs (3) into the pipe (7) and then introducing a batch of resin thereinto, or inserting one lining pig between two batches of a resin, or first inserting a lining pig and then inserting two batches of a resin with another lining pig therebetween, or first introducing a lining pig made of a soft material capable of deforming so as to pass through a narrow-passing section and then introducing a batch of a resin into the pipe, causing the resin to move forward until the front end of the resin reaches an inner end of the pipe (7), and sucking the resin back from the inner end so as to line the internal surface of the pipe with the resin. There are also provided improved liquid blocking pigs (6) for use in pipe lining treatment, each of such pigs (6) comprises a spherical body made of a soft resilient material and a least one flexible liquid barrier diaphragm interposed in the spherical body.
