摘要： There is provided an expandable pipeline pig for a varying diameter pipeline having a pig body that carries two or more guides and one or more actuators. Each guide has a resilient body with a folding zone between an outer perimeter and a central area connected to the pig body, a series of support members spaced circumferentially about the resilient body within the folding zone, and a series of collapsing structures positioned between, and integrally formed with, adjacent support members. The actuators selectively release the guides from a reduced to an expanded mode. In the expanded mode the support members extend outward and the collapsing structures are expanded between the support members. In the reduced mode the support members are folded toward the pig body and the collapsing structures are collapsed to reduce a circumference of the resilient body outer perimeter. The support members are biased toward the expanded mode.

摘要： A method for refurbishing an existing host pipe, in which an in-situ longitudinal cut is made in the interior wall of a subterranean host pipe. An expansion tool is moved along a path inside the host pipe, stopping at one or more stations on the way. At each station, responsive to isolated outward radial force from the expansion tool, the interior diameter of the host pipe is increased via separation of the longitudinal cut. A new rigid liner pipe is inserted inside the expanded host pipe to operationally replace the host pipe. In some embodiments, grout is deployed in the annular space between liner pipe and host pipe. Expansion of the host pipe via separation of the longitudinal cut optimizes the refurbishment job and enables the original host pipe, as expanded, to contribute structurally to the refurbished pipe system.

摘要： Disclosed is a pig assembly for maintaining a multi-diameter functional line with a large range of diameter variation for conveying fluid. The pig assembly includes a central shaft having a first shaft end and a second shaft end and at least one cylindrical pig body coaxially mounted on the central shaft. Attached to the at least one pig body are a plurality of arms capable of moving between an extended position radiating from the at least one pig body and a retracted position within the at least one pig body. Each of the pluralities of arms includes a spring to enable each arm of the plurality of arms to move into the extended position and to store potential energy when the arm is in the retracted position, and a roller to enable rolling contact between the pig assembly and an interior of a functional line during movement of the pig assembly within the functional line. The pig assembly further includes at least one set of a plurality of scraper elements located along the central shaft capable of rotating about the central shaft to move between an opened position and a collapsed position. A method for maintaining a multi-diameter functional line using the pig assembly is also disclosed.

摘要： A pipeline pig that can traverse dual- or multiple-diameter pipes or pipelines has collapsible and expandable sealing elements that support the pig, provide a sliding (dynamic) seal with the pipe wall, and maintain the necessary pressure for driving or cleaning as the elements collapse and expand. The sealing elements each have an internal cavity sized to house a first volume of a fluid and a reservoir sized to house a second volume of the fluid. The cavity and reservoir are arranged so that a portion of the volumes of the fluid can move between each. An accumulator maintains a pressure of the first and second volumes of the fluid so that regardless of the sealing element's current size, or whether the element is transitioning between sizes, the element can maintain a sliding seal engagement with the pipe wall and perform the primary function of driving or cleaning (or both).

摘要： A method and system for repairing, replacing or installing an underground pipeline using an appropriate tool head. A coolant, preferably a cryogenic liquid, is injected in front of the tool head to embrittle or otherwise reduce the toughness of the material ahead of the tool head. The method and system of this invention are particularly suitable for use in connection with pipe splitting and pipe bursting, where a pig disposed within the underground pipeline is connected with the appropriate tool head forming a space between the pig and the tool head into which the coolant is introduced. The pipe between the pig and the tool head is embrittled by the coolant, reducing the resistance of a pipe to splitting or bursting which, in turn, reduces the force required for the pig to pull the tool head as the pig is motivated through the pipe.

摘要： A pipe splitting assembly includes an articulating hammer nose assembly having a pipe splitting cutter and a rotatable joint coupled with the pipe splitting cutter. A pneumatic hammer is distal to the articulating hammer nose assembly, The pneumatic hammer is configured to drive the articulating hammer nose assembly proximally away from the pneumatic hammer. The rotatable joint is coupled between the pipe splitting cutter and the pneumatic hammer, and the articulating hammer nose assembly is rotatable into one or more angles relative to the pneumatic hammer through the rotatable joint. A cable coupling is interposed between the pneumatic hammer and the articulated hammer nose assembly. The cable coupling is configured to attach a cable to the pipe splitting assembly. The cable coupling and the rotatable joint are configured to transmit to the pipe splitting cutter a compression force from the cable coupling and dynamic percussive forces from the pneumatic hammer.

摘要： The invention shows pipe cleaning apparatuses for oil and gas pipelines in which a shield with a cleaning apparatus is moved forward by a liquid flow in the pipeline. The shield forms one or more apertures in the pipeline for a passing liquid flow in order to build up a predetermined pressure and is provided at its rear end with a braking apparatus which prevents undesirably large speeds of advance in that at least one clamping element adheres momentarily to the pipe wall and moves relative to the braking apparatus. This movement is kinematically transmitted to a hydraulic displacer which produces a secondary liquid flow that is braked via at least one throttle point and thus determines the speed between the shield and the pipe wall.
