Apparatus, systems and methods for plugging a high temperature pipe
摘要：
A method of plugging a pipeline includes the steps of welding onto the exterior of the pipeline (10) first (12) and second (14) spaced apart collars, each having a sealing face (26,26A) in a plane perpendicular the pipeline (10) axis. A containment housing (34,36) is affixed by welding to the collars (12,14) to fully encompass a section of the pipeline (10) between the collars (12,14). A tapping (60) machine is then removably attached to an open top of the containment housing (34). Using the tapping machine (60) a short length of the pipeline (10) is cut and removed from between the collars (12,14) leaving two open exposed pipe ends (78,80). First and second seal elements (92,94) are positioned between the collars (12,14), Each having a forward sealing face. The seal elements (92,94) are forced apart from each other into sealing engagement with the collar sealing faces thereby closing the open, exposed ends (78,80) of the pipe (10).
摘要（中）：

堵塞管道的方法包括以下步骤：将管道（10）的外部第一（12）和第二（14）间隔的套环焊接在一起，每个套环在垂直于管道的平面中具有密封面（26,26A） （10）轴。 密封壳体（34,36）通过焊接固定到套环（12,14），以完全包围套环（12,14）之间的管道（10）的一部分。 然后将轻敲（60）机器可移除地附接到容纳壳体（34）的敞开的顶部。 使用攻丝机（60），短的管道（10）的长度被从两个敞开的暴露的管端（78,80）之间的套环（12,14）之间被切割和移除。 第一和第二密封元件（92,94）位于套环（12,14）之间，每个具有前密封面。 密封元件（92,94）被迫使彼此分离成与套环密封面密封接合，从而封闭管（10）的敞开的暴露端（78,80）。
