    摘要： The present invention provides systems and methods for curing at least one leakage in a pipeline, the system including at least one fiber-in-sealant-in carrier fluid (FISIC) composition and at least one gel pig composition; wherein the at least one FISIC composition and the at least one gel pig form a pig train, are adapted to move along the pipeline to a region of the leakage and to seal and cure the at least one leakage.

    摘要： A method of repairing leakage in pipelines comprising the steps of forming a first and second openings (14a, 14b) in the pipeline (10) upstream and downstream, respectively, of the leakage location, inserting through the first opening (14a) a first body (C1), filling the space arrear of the first body (C1) with a first viscose sealing material (M1), inserting through the first opening (14a) a second body (C2) arrear of the first viscose sealing material (M1) compressing the first sealing material by applying a pressure against the first and the second bodies (C1, C2) in opposite directions, causing the first and second bodies (C1, C2) and the compressed first sealing material (M1) to move in unison in the direction of the second opening (14b), and retrieving the first and second bodies (C1, C2). Preferably, the method is performed using three bodies (C1, C2, C3) and two sealing materials (M1, M2).

    摘要： The present invention provides methods and systems for sealing at least one leak in at least one of at least one lateral pipe and a mains pipe, the method including passing a at least one of a pig train and said sealant composition under pressure along at least one of said main pipeline and said at least one lateral pipe such that a portion of the sealant composition enters at least one leakage site to seal and cure the at least one leak.
