用于清洁夹套管道单元的联接装置，系统和方法

COUPLING DEVICE, SYSTEM, AND METHOD FOR CLEANING JACKETED PIPES UNITS
Abstract:
A coupling device (20), a system (50,150,250), and a method for transferring a pig between inner tubes (12) of a jacketed pipes unit (11) (JPU) to clean the inner tubes (12). The coupling device (20) includes a mounting block (30). The mounting block (30) has at least first and second openings (33) extending through the mounting block (30). Each opening (33) is in fluid communication with a corresponding inner tube (12) when the mounting block (30) is mounted to the JPU (11). The coupling device (20) also has a looping conduit (40) connecting two of the inner tubes (12) in serial flow communication. The looping conduit (40) extends between a first loop end (41) mounted to the mounting block (30) about the first opening (33), and a second loop end (42) also mounted to the second surface (32) of the mounting block (30) about the second opening (33). The looping conduit (40) in use transfers the pig from one of the inner tubes (12) of the jacketed pipes unit (11) to another one of the inner tubes (12).
Abstract(Chinese):

耦合装置（20），系统（50,150,250）以及用于在夹套管单元（11）（JPU）的内管（12）之间转运猪以清洁内管（12）的方法。 联接装置（20）包括安装块（30）。 安装块（30）具有延伸穿过安装块（30）的至少第一和第二开口（33）。 当安装块（30）安装到JPU（11）时，每个开口（33）与相应的内管（12）流体连通。 联接装置（20）还具有以串联流动连通方式连接两个内管（12）的环形导管（40）。 环形管道（40）在围绕第一开口（33）安装到安装块（30）的第一环路端（41）和第二环路端（42）之间延伸，第二环路端口（42）也安装到第二环路端 安装块（30）围绕第二开口（33）。 使用的环形管道（40）将猪从套管管单元（11）的内管（12）之一转移到另一个内管（12）。
