| 摘要 |
<p>The present invention relates to an equipment (1) for the interconnection of two lines (3,4) to allow running of pigs. Particularly, it is applied to subsea pipelines. This device allows the pigging in installations with restricted accessibility. This equipment enables pigs launched from a first site into the first line, to return via the second line back to the first site. Due to its modular design it can be installed at any point of a pipeline system, even with existing facilities. <IMAGE></p> |
