Apparatus for applying multi-component liquid liner compositions to the inner surfaces of conduits and methods of applying same

Abstract

The invention is directed to an apparatus, or system, for applying a multi-component liquid liner composition to an inner surface of a conduit. The system comprises a first reservoir having a first liquid liner component; a second reservoir having a second liquid liner component, the second liquid liner component being different from the first liquid liner component; a first liquid liner component transmission line in communication with the first reservoir; a second liquid liner component transmission line in communication with the second reservoir; and an applicator in communication with the first and second liquid liner component transmission lines. Methods of applying multi-component liquid liner compositions to the inner surface of conduits are also disclosed.

         12 . A method of applying a multi-component liquid liner composition to an inner surface of a conduit, comprising the steps of: 
 providing a conduit having an inner surface;    transmitting a first liquid liner component to an application site disposed on the inner surface of the conduit;    transmitting a second liquid liner component to the application site, the second liquid liner component being different from the first liquid liner component;    mixing the first liquid liner component with the second liquid liner component at the application site to form a multi-component liquid liner composition; and    applying the multi-component liquid liner composition to the inner surface of the conduit at the application site.    
     
     
         13 . The method of  claim 12 , wherein a third liquid component liner component is transmitted to the application site and mixed with the first and second liquid liner components to form the multi-component liquid liner composition applied to the inner surface of the conduit at the application site.  
     
     
         14 . The method of  claim 12 , wherein the multi-component liquid liner composition includes at least two additional liquid liner components that are transmitted to the application site and mixed with the first and second liquid liner components to form the multi-component liquid liner composition applied to the inner surface of the conduit at the application site.  
     
     
         15 . The method of  claim 12 , wherein the conduit is a production tubular and the application site is disposed at least 200 feet below ground.  
     
     
         16 . The method of  claim 12 , wherein the multi-component liquid liner composition is applied to the inner surface of the conduit by centrifugal spraying.
