Abstract: A spray coating system includes a spraying robot sized to fit within a conduit. The spraying robot includes arms that extend outward and retract inward to maintain contact with an interior surface of the conduit. The spraying robot is configured to be coupled with hoses that separately supply different fluids to the spraying robot. The spraying robot includes a spray head from which a compound formed from the fluids is sprayed onto the interior surface of the conduit. The spraying robot is configured to be pulled through the conduit and/or self-propel in the conduit to spray the compound onto the interior surface of the conduit and form a coating thereon.

Abstract: A spray coating system includes a rotating spray head and a transfer assembly. The spray head is coupled with a spray nozzle that directs spraying of a fluid multi-component product onto an interior surface of a structure. The spray head rotates around a longitudinal axis in order to cause the spray nozzle to also rotate around the longitudinal axis while spraying the multi-component product onto the interior surface of the structure. The transfer assembly is fluidly coupled with the spray nozzle and supplies plural different fluids that form the multi-component product to the spray nozzle. The transfer assembly supplies the different fluids that form the multi-component product to the spray nozzle without mixing the different fluids with each other prior to the different fluids being disposed proximate to the at least one spray nozzle.

Abstract: A method of refurbishing a beverage storage tank having a lined interior surface. The interior surface of the beverage storage tank is sprayed with a fluid jet to remove lining and surface contaminates from the beverage storage tank. The interior surface of the beverage storage tank is abrasive blasted to prepare the interior surface of the beverage storage tank, and a beverage safe coating material is applied to the prepared interior surface of the beverage storage tank.
