摘要： A plugging device for double blocking a section of pipeline or piping and method for its use includes a first and second sealing element and at least one cylinder that is extendable along an axial direction of the pipe between a retracted first position and an extended second position. A means for actuating the cylinder, such as a fluid power source, is provided. When the cylinder is in the extended second position, the sealing element sealably engages an opposing cut end of the pipe. The sealing element is an elastomeric sealing element and may be cup-shaped, convex-shaped, or cork-shaped.

摘要： A pipe plug comprised of two, pivotally connected plugging heads, each plugging head having a sealing element, which work in combination to double block and bleed a pipe. The first sealing element prevents flow of product in the pipe and the second sealing element captures any leakage past the first sealing element and forces that leakage out through a fitting. A stabilization pad, connected to a flange on a nosepiece of each plugging head, prevents deformation of the sealing elements. A spring-loaded pivot arm connected to the second plugging head allows the yoke that connects the two plugging heads to rotate freely. An outward-facing raised taper projection on the pivot arm, along with a guide wheel connected to the first plugging head, prevent the yokes and plugging heads from becoming entrapped during their installation in or removal from the pipe.
摘要翻译：一个管塞，包括两个枢转连接的堵塞头，每个堵塞头具有一个密封元件，它们组合起来加工成两个块并排出一个管子。第一密封元件防止产品在管道中的流动，并且第二密封元件捕获通过第一密封元件的任何泄漏并且迫使通过配件渗出。连接到每个堵塞头的喷嘴上的凸缘的稳定垫防止密封元件的变形。连接到第二堵塞头的弹簧支撑臂允许连接两个堵塞头的轭自由旋转。在枢转臂上的向外凸起的锥形突起以及连接到第一堵塞头的引导轮防止了轭和堵塞头在其安装在管道中或从管道移除时被夹带。

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).
摘要翻译：一种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）间隔开的套环焊接在一起，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）。

摘要： A pipe plug includes two or more pivotally connected plugging heads that work in combination to double block and bleed a pipe. At least one of the plugging heads has an expandable sealing element that is in communication with an inflation source. The sealing element may be an inflatable sealing element or a compression packer sealing element. A passageway-sections of which may pass through the pivotal connection and into the plugging head-carries the inflation medium from the source to the sealing element. A bleed port passageway is also provided that passes through the plugging head. The leading plugging head may include a cleaning element for sweeping away debris ahead of the plug. The plugging heads may also include a skid plate that slideably engages the interior surface of the pipe to properly orient the plugging heads within the pipe.
