20090061098 | METHOD AND SYSTEM FOR PREHEATING EPOXY COATINGS FOR SPRAY APPLICATION - A method and system for the spray application of epoxy materials is provided. The system includes a dual walled tank structure as a reservoir for containing and preheating the epoxy materials in preparation for mixing and spray application. Each component of the epoxy material is preheated before the components are mixed. After preheating, the components are then mixed together and spray applied. The method and system of the present invention provides a high quality spray applied epoxy coating while reducing equipment down time and cleaning. | 03-05-2009 |

20140034178 | METHOD AND COMPOSITION FOR LINING A PIPE - A pipe lining composition and a method for installing the pipe lining composition into a pipeline requiring repair is provided. The lining composition is a layered lining composite formed of alternating plies of felt and carbon fiber strand reinforcing such that layers of carbon fiber reinforcing strands are trapped between layers of felt. Once the composite is laid up the composite is preferably stitched to provide stability and to maintain the layers relative to one another and then formed into a tube. In accordance with the method, the lining tube is then sequentially filled resins of increasing viscosity as it is drawn through rollers in a manner that fully wets out the carbon fiber before it is placed into the pipe to be lined. | 02-06-2014 |
20140319416 | EPOXY ENCAPSULATED FLUORESCENT COATING - A structural epoxy coating blended with a high output fluorescent material. Further other materials may be blended in optimal embodiments including fumed silica and reflective beads. What sets this new product apart from others in the market is the fact that the product is extremely strong and rugged with extreme wear characteristics in very harsh conditions. The base epoxy, P301 epoxy manufactured by Warren Environmental, has passed the US Navy QPL list and is rated #1 based on navy testing for long term service life in sewer conditions. The base epoxy product is NAVSEA approved for salt water exposure and ocean spray, storage of hazardous materials, fuel tanks, salt water boxes, raw sewerage etc. | 10-30-2014 |
20150020908 | PRESSURE INFUSION LINING SYSTEM - A method and system for applying a liner to an underground utility structure is provided. First a layer of epoxy is applied to the interior surface of the host pipe using a machine such as a spincast machine. A dry liner is inverted into the pipe directly behind the coating application at a limited speed and pressure. A drag is set on the inversion equipment relative to the speed of the epoxy spinner unit to control inversion speed. Once the liner is completely inverted the internal pressure of the liner is raised and infused into the uncured epoxy. | 01-22-2015 |
20150114507 | METHOD AND SYSTEM FOR COATING A PIPE - A method and system for evaluating the interior surface and exterior wall conditions of a pipeline while also dynamically installing a repair coating in a pipeline, such as an underground water pipeline. The system is towed into the pipeline and drawn back therethrough. As the system is drawn back, one module in the system evaluates the surface condition of the interior of the pipe and another module evaluates the structural condition of the wall of the pipe. Based on the evaluation data obtained from the two modules an epoxy material is applied to the interior surface of the pipe using a spin cast machine that is drawn behind the two modules. Preferably, a layer of epoxy is applied to the interior surface of the host pipe to the appropriate thickness based on the pipe condition as determined by the two modules. | 04-30-2015 |
