LINER FOR REPAIRING A LATERAL CONNECTION OF A PIPELINE WITH INTEGRAL TRANSITION REGION BETWEEN MAIN LINING PART AND LATERAL LINING PART.

摘要

A liner (5) is disclosed for repairing a connection between a main pipeline and a lateral pipe. The liner includes a main pipeline lining part (12) that in use forms a tubular portion for lining an inner circumferential portion of the main pipeline and a lateral pipe lining part (14) that in use forms a tubular portion for lining an inner circumferential portion of the lateral pipe. Between the lateral pipe lining part (14) and the main pipe lining part (12) there is a transition zone (16) that in use is arranged to line a junction zone between the main pipeline and the lateral pipe. The transition zone (16) is formed integrally with both the main pipeline lining part (12) and the lateral pipe lining part (14).
