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.

1 - 16 . (Cancelled).  
     
     
         17 . 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;    applying the first liquid liner component to the inner surface of the conduit at the application site; and    applying the second liquid liner component to the inner surface of the conduit at the application site thereby forming a multi-component liquid liner composition disposed on the inner surface of the conduit at the application site.    
     
     
         18 . The method of  claim 17 , wherein at least one additional liquid liner component is transmitted to the application site and applied to the inner surface of the conduit to form the multi-component liquid liner composition disposed on the inner surface of the conduit at the application site.  
     
     
         19 . The method of  claim 17 , wherein the conduit is a production tubular and the application site is disposed at least 200 feet below ground.  
     
     
         20 . The method of  claim 17 , wherein the first and second liquid liner components are applied to the inner surface of the conduit by centrifugal spraying.
