摘要： A device for emptying fluid from a pipe and for filling the pipe with another fluid while preventing the fluids from mixing comprising a sealing gasket attached to the head end of a tubular support member which presses against the inner wall of the pipe to maintain the separation of the fluids while also drying the inner wall, and a breaking unit attached to the support member for slowing the movement of the device within the pipe thereby slowing the velocity of the fluid filling the pipe.

摘要： Provided herein are a pipeline inspection system for effectively managing a pipeline by inspecting a state of the pipeline while moving along the pipeline. Moreover, the pipeline inspection system and the maintenance method using the same can improve scale removal efficiency by removing scale accumulated on the inner wall of the pipeline with ultrasonic vibrations, and prevent water leakage due to the corrosion of the inner wall of the pipeline.

摘要： The present disclosure relates to a pig which is insertable at least partly within a fabric liner sleeve located in a duct and which is capable of heating the liner sleeve in situ in the duct to melt thermoplastic material of the liner sleeve to form, on subsequent cooling of the melted thermoplastic material, a rigid liner in the duct. The pig comprises: a gas inlet (1008) for receiving pressurised gas; a heating chamber (17) in which the pressurised gas is heated; and a gas outlet (1009) via which pressurised gas heated in the heating chamber (17) is deliverable to the fabric liner sleeve.
The pig comprises a tree diffuser (15) located in the heating chamber (17) via which pressurised gas can be delivered into the heating chamber (17).
The tree diffuser (15) has a plurality of branch pipes (A,B,C) each comprising at least one gas delivery aperture, each branch pipe (A,B,C) extending outwardly from a trunk portion of the tree diffuser (15).

摘要： The present invention relates to an apparatus and method for joining a longitudinal seam in a tube, to an apparatus and method of joining a longitudinal seam in a tube in a borehole, to an apparatus and method of repairing a tube and to a pig. In an aspect an apparatus is provided for joining a longitudinal seam in a tube. The apparatus (200) includes a spool (202) for progressively unwinding a coiled member (10) into an extended form (12). The member (10) transitions from a flat form when coiled (11) to a slit tube form when extended (12), in which form the member is resiliently biased. A joining device (214) is positioned downstream of the spool arranged to provide energy to a portion of the member in its extended form to cause heating so as to progressively join together the longitudinal edges of the slit tube as the member passes the joining device. A longitudinal seam (20) is thereby formed in the tube.

摘要： A pipe loosening device and methods are shown. In one example, the pipe loosening device enables a method wherein a pipe to be replaced is deformed but not burst, and a portion of a sidewall of the pipe is forced outward into the surrounding soil to compact a local region of the surrounding soil and loosen the existing pipe. The pipe may then pulled from the ground along an axis of the pipe.

摘要： System and method for decommissioning a pipeline. The system comprises mechanical and chemical assemblies. The mechanical assembly includes a main body and a contact assembly. When the mechanical assembly is provided in the pipeline, the contact assembly is configurable to contact with the interior wall of the pipeline. The chemical assembly is arranged serially in line with the mechanical assembly. The chemical assembly includes a front section having a cross-sectional portion and a rear section having a cross-sectional portion. The front and the rear section are arranged in such a way that the cross-sectional portions of the front and the rear section cooperate with the interior wall of the pipeline to form a chamber to house a removal medium. The system and method can effectively and efficiently remove most or all of such residual mercury and/or other toxic substance from the interior wall of the pipeline before abandonment.

摘要： An annular seal for a conduit pig includes an annular diaphragm and a separate lead support structure. The annular diaphragm is devoid of internal supports and therefore quite flexible. However, the lead support structure supports the annular diaphragm such that a piston effect can be generated through the annular seal. A brush portion for a conduit pig may include forwardly raked bristles.

摘要： A pipe rehabilitation system and/or robot can be used inside a pipe to measure characteristics of branch conduits, install plugs into branch conduits before the pipe is lined with a liner, remove portions of plugs and liners after lining to restore fluid communication between the pipe and branch conduits, and/or install fittings into the branch conduits to connect the liner to the branch conduits. A probe can measure characteristics of a branch conduit. A tool can install plugs and/or fittings into the branch conduits. A linkage can connect a tool to a robotic tractor so that the connected elements can navigate through a main pipe. A visualization system can aid in aligning a robot with a branch conduit. Height-adjustable braces can support robotic tools in a pipe. A plug can include integrated locating features and/or movable parts that enable expanding the plug to seal with the branch conduit.
