    Abstract: A pipeline cleaning apparatus and method configured for use in cleaning and clearing a pipeline of transient fluids, hydrocarbons, and other unwanted debris is disclosed. The apparatus and method utilizes a vacuum assembly haying a collection tank connected to a pipeline by at temporary vacuum line. Negative pressure created by the vacuum assembly causes a compressible pig to move down the length of the pipeline and up the temporary vacuum line to push transient hydrocarbons, fluids, and other unwanted debris from within the pipeline to the collection tank. The removal of hydrocarbons and non-hydrocarbons from the pipeline cleans the pipeline and allows the pipeline to be abandoned while complying with federal regulations.

  • Patent number: 8752542
    Abstract: Solar energy generates steam in a “once-through” configuration without recirculation, with closely managed steam quality, to produce wet steam from high-contaminant feed water without scaling or fouling. Feed water is pressurized, preheated, and evaporated in a series of pipes exposed to concentrated solar energy to produce a water-steam mixture for direct distribution to an industrial process such as enhanced oil recovery or desalination. Water flow rates are managed based on measurements of solar energy and steam production to manage variations in the solar energy. Steam generator piping system uses continuous receiver pipe that is illuminated by segmented parabolic mirrors enabled to track the sun. Provisions for steam generator piping recurring maintenance are provided. Thermal energy from hot condensate and/or from low quality steam is recaptured and warms inlet water.

It comprises radial projections that are flexible along the axial direction, suitable for polishing the inside walls of tubes merely by relative movement between the shuttle and the tube, the shuttle passing inside the tube. In a longitudinal section, the sections of the projections form a series of separate undulations that are long and thin in the radial direction. The polishing method made possible by the shuttle is particularly simple, since a single pass of the shuttle can suffice for performing polishing; the method is thus fast and easy to automate, e.g. in a polisher device of the invention.

  • Patent number: 7739767
    Abstract: A liquid transport system has a number of access points, referred to generally as nodes, connected to an endless loop of piping such that liquid flowing in the system, to move the liquid from one node to another, flows in two generally discrete paths from a source node to a destination node. In general, any node can be associated with either a liquid source or a liquid destination. A source in a first liquid transfer can act as a destination in a subsequent liquid transfer, and vice versa. A single pigging system can be used to clean substantially the entirety of the liquid transport system among all sources and all destinations, except for leads from the nodes to the sources and/or destinations. The liquid transport system can be cleaned in place, thus to clean all of the piping which runs between the respective nodes in the liquid transport system.

  • Publication number: 20100083988
    Abstract: The invention relates to a method of cleaning a pipe (12) by action of a fluid under very high pressure. It is characterised in that the fluid under very high pressure is caused to pass in a flexible tube (14); said tube is subjected to the action of motorisation means (5) for longitudinal advance, and means for driving the tube (14) in rotation around its longitudinal axis; these motorisation means (50) are regulated by management means (48) and rotation detection means (47) and/or pinpointing longitudinal advance, and these means of driving in rotation; the tube (14) is guided near the entrance of the pipe (12). The invention also relates to a device for implementing this method.

  • Patent number: 7645346
    Abstract: A cleaning apparatus useful for cleaning the interior of a pipeline contains: (A) a platform of a dimension sufficient to be inserted through an opening in the pipeline, the platform containing one or more portions; (B) a fluid interrupter having one or more parts to provide a surface to contact fluid flow and thereby interrupt fluid flow, the fluid interrupter constructed and arranged to be attached to the platform; a downstream side of the fluid interrupter being supported by members connected to the platform to dispose the fluid interrupter against fluid flow; (C) runners attached to the underside of the platform to contact an inner diameter of the pipeline; whereby the supported fluid interrupter, platform and runners redirect fluid flow between an underside of the platform and an inner surface of the pipeline; and (D) a device located downstream of the fluid interrupter to constrict the volume of the redirected fluid and increase its flow rate; whereby fluid flow is increased to move solid waste in the p

  • Patent number: 7624806
    Abstract: A method of cleaning a pipe provides a tool within the pipe. The tool has a body of smaller diameter than the pipe such that the body and pipe define an annulus and a fluid guiding member located at the annulus and movable relative to the pipe. The fluid guiding member moves relative to the pipe to guide fluid forward of the fluid guiding member to a pipe outlet.

  • Patent number: 7536742
    Abstract: An apparatus for pushing a dual diameter pig through a conical reducer attached to a pig trap and into a pipeline includes a frame configured such that the pig rests and moves forward on the frame, which has a front end adapted for attachment to the trap. The vertical position of the frame can be adjusted to align the pig with the conical reducer. An actuator is supported on the frame rearward of, and aligned with, the pig and an actuator control extends the actuator into contact with the rear end of a pig, and also retracts the actuator. The actuator locks to the frame at lock locations spaced along the frame, and the lock locations are separated by a distance that is less than a stroke of the actuator. The pig is pushed into the trap in steps by repeatedly extending, retracting, and moving the actuator forward.

    Abstract: A device for washing liquid turbulation for rotary jet heads, especially for water-cleaning machines. The head comprises a main body exhibiting an inlet, coupled with a closure body, exhibiting an outlet, and defining together with the main body, an internal chamber. A dispensing nozzle of the washing liquid is housed in the internal chamber and is mobile with a conical rotary motion having a vertex thereof in the frontal portion. The turbulation device, also located in the internal chamber upstream of the nozzle, comprises means for conveying for facilitating a flow of liquid from the inlet to the internal chamber with helical motion, impressing the conical rotary motion on the nozzle.

  • Patent number: 7406738
    Abstract: A thruster pig for sending through a pipe from an entrance facility to a receiving location, for servicing or monitoring, by pumping a thrusting fluid into the pipe to force the pig forward is disclosed. The thruster pig includes a body having a front end and a back end, where the back end includes a reaction surface to which said the thrusting fluid applies a motive force. The body is slightly smaller in diameter than the inner diameter of the pipe. The pig also includes a seal circumferentially arranged on the pig to seal between said body and said pipe. A desired differential pressure is maintained over the pig to urge said pig forward through the pipe by pumping a fluid into the annulus between the pipe and the return flow line while returning fluid through said return flow line utilizing connected servicing or monitoring equipment. A connector releasably connects a return flow line to the pig.

  • Patent number: 7213290
    Abstract: The invention concerns a pig scraper for cleaning the inside wall of a coating agent conduit. The pig scraper includes a body insertable in the conduit and at least one sealing lip that seals against the inside wall of the conduit and extends parallel to a longitudinal axis of the body. A space is defined between the sealing lip and the body to form a pocket for enhancing the sealing of the sealing lip with respect to the conduit. The length of the sealing lip substantially prevents the lip from folding over on itself in response to a change in the direction of movement of the pig scraper in the conduit.
