  • Patent number: 10041790
    Abstract: A misalignment calculation system comprising a misalignment calculator for calculating a misalignment occurring in butt welding of end portions of a first steel pipe and a second steel pipe by using profile data measured in a circumferential direction on the first steel pipe end portion by presetting a first angle datum, and profile data measured in a circumferential direction on the second steel pipe end portion by presetting a second angle datum. The misalignment calculator calculates the misalignment amount in a state in which an angle formed between the first and second angle datums is adjusted to an input angle and in which the center of profile data showing an external surface geometry at the first steel pipe end portion is aligned with the center of the profile data showing an external surface geometry at an end portion of the second steel pipe so that misalignment can be evaluated.

  • Patent number: 9982828
    Abstract: The method for rehabilitating a damaged section of a pipe without a need for a resin absorbent liner is provided. The method includes pumping a low viscosity material towards a damaged section of pipe and changing the viscosity prior to dispensing of the material. For example, the material may be partially cured prior to dispensing. The partially cured or higher viscosity material is compressed between an inflating bladder and interior wall of the pipe, and the material that is allowed to fully cure. The bladder either can then be removed from the pipe or could be allowed to maintain in the pipe providing a new interior surface for the repaired pipe.

    Abstract: Apparatus and methods for lining a pipe line having a first pipe section in communication with a second pipe section where the first pipe section has an inside diameter greater than an inside diameter of the second pipe section. A transition tube having an outside diameter substantially equal to the inside diameter of the second pipe section and a length substantially equal to or greater than the length of the first pipe section is inverted into the pipe line along with a liner. A resinous material applied to the liner cures and hardens the liner after inversion.

  • Patent number: 9512951
    Abstract: An apparatus for replacing an existing pipe. The apparatus comprises a slitter and expander which surround a wire rope. The wire rope is attached to the expander, and the expander abuts either the slitter or a separation tube disposed between the expander and slitter, such that the slitter and expander are pivotable relative to each other. The apparatus is placed in a pipe to be replaced and pulled. While being pulled, blades on the slitter slit the pipe, while a sloped surface of the expander moves the slit sections apart into surrounding soil. A replacement pipe may be pulled by a pipe putter attached to the expander. A beacon may also be disposed within the apparatus to emit a signal for locating the apparatus white underground.

  • Patent number: 9352357
    Abstract: Methods and systems for cleaning, coating and sealing leaks in existing pipes, in a single operation. A piping system can be cleaned in one pass by dry particulates forced and pulled by air throughout the piping system by a generator and a vacuum. Pipes can be protected from water corrosion, erosion and electrolysis, extending the life of pipes such as copper, steel, lead, brass, cast iron piping and composite materials. Coatings can be applied to pipes having diameters up to approximately 6?. Leak sealants of at least approximately 4 mils thick can cover insides of pipes, and can include novel mixtures of fillers and epoxy materials, and viscosity levels. A positive pressure can be maintained within the pipes during applications. Piping systems can be returned to service within approximately 96 hours.

  • Patent number: 9353888
    Abstract: A polymer bag grouting method for repairing a settlement of an underground pipeline includes steps of: (1) detecting a settled pipeline section and determining a grouting plan; (2) drilling holes for containing bags; (3) placing the bags into the holes; (4) injecting a polymer material into the bags; (5) uplifting the settled pipeline section; and, (6) filling a cavity and reinforcing a soft soil layer. The polymer material is a non-water reacted two-component polymer material. The method provided by the present invention has advantages of rapidness, small cut, light mass, high tenacity, economy and durability. The method is advanced, highly-efficient, economical and practical and able to rapidly repair the settlement of the pipeline section through uplifting. The method of the present invention is successfully applied to multiple projects of uplifting the underground pipelines, showing great economic and social benefits and a wide development and application prospect.

  • Patent number: 9163770
    Abstract: The method for rehabilitating a damaged section of a pipe without a need for a resin absorbent liner is provided. The method includes pumping a low viscosity material towards a damaged section of pipe and changing the viscosity prior to dispensing of the material. For example, the material may be partially cured prior to dispensing. The partially cured or higher viscosity material is compressed between an inflating bladder and interior wall of the pipe, and the material that is allowed to fully cure. The bladder either can then be removed from the pipe or could be allowed to maintain in the pipe providing a new interior surface for the repaired pipe.
