Pipeline

Abstract

A pipeline.

1 . A method of joining a second tubular member to a first tubular member in a pipeline, the first tubular member having an inner diameter greater than an outer diameter of the second tubular member, comprising: 
 positioning an expansion device within an interior region of the second tubular member;    pressurizing a portion of the interior region of the second tubular member; and    radially expanding and plastically deforming the second tubular member using the expansion device into engagement with the first tubular member;    wherein an interface between the expansion device and the second tubular member does not include a fluid tight seal.    
   
   
       2 . A method of fluidicly isolating a section of pipeline tubing, comprising: 
 running a length of expandable tubing into pipeline-lined borehole and positioning the expandable tubing across a section of pipeline to be fluidicly isolated; and    plastically deforming at least one portion of the expandable tubing to increase the diameter of the portion to sealingly engage the pipeline to be fluidicly isolated by displacing an expansion device therethrough in the longitudinal direction.    
   
   
       3 . A tubular liner in a pipeline, comprising: 
 an annular member, the annular member comprising one or more sealing members at an end portion of the annular member; and    one or more pressure relief passages defined only at the end portion of the annular member.    
   
   
       4 . A tubular liner in a pipeline, comprising: 
 an annular member having a first portion, a second portion, and a third portion;    wherein the wall thickness and outside diameter of the first, second and third portions range from about ⅜ to 1.5 inches and 3.5 to 16 inches, ⅛ to 1.25 inches and 3.5 to 19 inches, and ⅛ to 1.25 inches and 3.5 to 19 inches, respectively.    
   
   
       5 . An apparatus for expanding a tubular liner in a pipeline, comprising: 
 a support member;    an expansion device coupled to the support member;    a tubular liner coupled to the expansion device; and    a shoe coupled to the tubular liner, the shoe defining a passage;    wherein the interface between the expansion device and the tubular liner is not fluid tight.    
   
   
       6 . A system for joining a second tubular member to a first tubular member in a pipeline, the first tubular member having an inner diameter greater than an outer diameter of the second tubular member, comprising: 
 means for positioning an expansion device within an interior region of the second tubular member;    means for pressurizing a portion of the interior region of the second tubular member; and    means for radially expanding and plastically deforming the second tubular member using the expansion device into engagement with the first tubular member;    wherein an interface between the expansion device and the second tubular member does not include a fluid tight seal.    
   
   
       7 . A system for fluidicly isolating a section of pipeline tubing, comprising: 
 means for running a length of expandable tubing into pipeline-lined borehole and positioning the expandable tubing across a section of pipeline to be fluidicly isolated; and    means for plastically deforming at least one portion of the expandable tubing to increase the diameter of the portion to sealingly engage the pipeline to be    fluidicly isolated by displacing an expansion device therethrough in the longitudinal direction.
