摘要

Anew technology for the external rehabilitation of pipelines known as Xhab® has been developed by Pipestream Inc. This technology involves wrapping multiple layers of ultra-high strength steel (UHSS) strip in a helical form continuously over an extended length of and be able to reinforce or replace the pipe section before overall pipe failure occurs. An inline inspection (ILI) trial has been performed on a test section of pipe containing an XHab repair with intentional defects in both the pipe wall and the repair strips. The trial was conducted by T.D. Williamson, Inc.(TDW) using an ILI tool containing both axial mag- start and finish of repair; 2) resolution of pipe wall defect filled with epoxy filler material (both organic-filled and metal-filled epoxy); 3) resolution of individual UHSS strip layers in the repair; and 4) resolution of metal loss defects within strip layers (both above pipe wall defects and full pipe wall).

Williamson,Inc.(TDW)使用ILI工具进行的,该工具既包含轴向磁矩,也包含修复的完成; 2)解决用环氧树脂填充材料(有机填充和金属填充的环氧树脂)填充的管壁缺陷的解决方案; 3)修复中各个UHSS条带层的分辨率; 4)解决带状层内的金属损耗缺陷(在管壁缺陷上方和整个管壁上方)。
