Abstract: A method and system for inserting a liner and lining pipes from inside a water main or other larger pipe. The method and system generally includes inserting a string inside the first pipe between a first end and a second end, inserting the string through a liner positioning tool, attaching a first end of the string to the liner, and then pulling the liner into the first pipe with the first string such that the liner extends from the first end to the second end of the pipe. One end of the string may be attached to the liner by a pulling insert, which may be a threaded insert that screws into an end of the liner, and which may further include a fluid passage to allow hot water or other fluid to flow through the insert while the string is connected to it.

Abstract: A pipe liner re-flaring system and method for use with a water pipe containing a pipe liner. The pipe liner re-flaring system and method generally include a compression coupling comprising a pair of female compression fittings and a dual ended male compression fitting connected between the female compression fittings. The female compression fittings are adapted to fit over and secure the lined water pipe and a second pipe to be joined with open ends of the pipe liner and the pipe to be joined in direct contact within the male compression fitting. A pipe liner expansion tool and a pipe liner flaring tool are used to expand and re-flare the open end of the pipe liner so that the pipe liner is in contact with an inner wall of the compression coupling to prevent leakage and contact between fluids flowing in the pipes and the material of the pipes and compression coupling.

Abstract: A pipe tool positioning system for efficiently inserting, positioning, and orienting a tool for use within a pipe. The pipe tool positioning system generally includes a sleeve with a receiver opening adapted to receive and removably retain a tool such as a grinder or the like. The sleeve includes radially-offset bladders extending outwardly from its outer surface. Each of the bladders may be individually inflated and/or deflated to aid in positioning of the tool within a pipe. A control unit may be provided with controllers for individually controlling each of the bladders. A camera may also be included adjacent to the sleeve to feed a display included with the control unit. By utilizing the present invention, various tools may efficiently be inserted and positioned for use within a pipe.

Abstract: A conduit treatment system for uniformly apply coatings or treatments to the inner walls of conduits without excessive build-up or creation of blockages. The conduit treatment system generally includes a tube having an absorbent first layer and a non-absorbent second layer. When not inverted, the first layer is the interior of the tube and the second layer is the exterior of the tube. The first layer will be adapted to absorb a treatment which is to be applied within a conduit. By securing a tether between an inversion unit and a closed-off end of the tube, the tube may be wound onto the inversion unit's shaft. The first end of the tube may then be anchored to the inversion unit's connector head to allow for inversion of the tube within a conduit. Upon inversion, the first layer will apply its absorbed treatment to the inner walls of the conduit.

Abstract: A remote pipe lining air monitoring system for remotely monitoring air pressure when curing a pipe liner. The present system generally includes a case storing an internal monitoring system. The case includes a port which is adapted to be fluidly connected in-line between an air compressor and a pipe liner. An internal compartment of the case includes the various components of the monitoring system, including a communications device, illumination device, air pressure monitor, alarm device, and a camera. The illumination device illuminates the internal compartment of the case while the camera is directed at the air pressure monitor. The communications device remotely transmits a video signal of the monitor to a remote device. In the event of pressure change or loss of power, the audio detector will detect activation of the alarm device and cause an alert to be transmitted to a remote device by the communications device.

Abstract: A laminated pipe lining system reduces or eliminates the risk of liner and seam failure due to stress and eases installation in small diameter pipes or pipes with multiple bends. The present invention generally includes a plurality of liners which are layered to line the inner surface of a conduit such as a utility pipeline. Each of the liners will generally include its own seam which is a product of the fabrication of the liners. The first liner is first inserted through the conduit and cured against the inner surface of the conduit. The second liner may then be inserted through the first liner and cured against its inner surface. The third liner may then be inserted through the second liner and cured against its inner surface. Each of the seams will be radially offset with respect to each other to protect the structural integrity of the lining system.

Abstract: A method and system for lining pipes which utilizes an in-line water heater to improve efficiency when lining long lengths of pipe. The method and system for lining pipes generally includes a pipe lining machine and a water heater. The outlet of the pipe lining machine will generally be connected to the inlet of the water heater by a first conduit. The outlet of the water heater will generally be connected to a second conduit and the linet of the pipe lining machine will generally be connected to a third conduit. A non-metallic liner is extended through the pipe to be lined and connected at either end to the respective ends of the pipe, the end of the second conduit and the end of the third conduit. By placing a water heater in-line with the pipe lining machine, the pipe lining capability of the pipe lining machine may be greatly improved.

The CIPP chilled lubrication system generally includes a lubricant applicator having a reservoir filled with a gel lubricant and a plurality of rollers that guide the CIPP liner through the gel lubricant prior to entry into an air inverter unit. The gel lubricant is chilled to a temperature of 35 degrees Fahrenheit or lower prior to being applied to the CIPP liner.

Abstract: A pipe direction and size indicator which may be attached to a pipe inspection camera for use in determining the flow direction and size of a pipe. The pipe direction and size indicator generally includes an adapter member, extension member and indicator member. The adapter member is adapted to be removably attached to a camera. The extension member is removably secured to the adapter member by a threaded connection. The outer end of the extension member includes an indicator member which is attached thereto and allows the indicator member to freely rotate, swivel and move about the extension member. By observing the positioning of the indicator member, which will be freely affected by gravity, an operator of the present invention may determine the directional flow of a pipe being inspected. Further, by accounting for the size of the indicator member, the size of the pipe may also be determined.
