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： An isolation tool is adapted for location in a pipe and includes a first plug module and a second plug module. The first plug module is configurable to grip the pipe and permit fluid bypass, to prevent fluid bypass without gripping the pipe, and to isolate the pipeline with gripping and leak tight sealing allowing a section to be fully de-pressurised. In use, the first and second plug modules are inserted into opposite ends of the pipe. The first plug module is pigged to a location in the second mode with a seal against the pipe but no grip then is configured in the fluid bypass mode when the second plug module is travelling through the pipe so that fluid displaced by the second plug module bypasses the first plug module. The second plug module and first plug module are then sealingly secured to the pipe to isolate a section of the pipe wall having a restriction.
摘要翻译：隔离工具适于位于管道中并且包括第一插头模块和第二插头模块。第一个插头模块可配置为夹紧管道并允许流体旁路，以防止流体旁路而不夹紧管道，并且通过夹紧和密封密封来隔离管道，从而允许部分完全减压。在使用中，第一和第二插头模块插入管道的相对端。当第二插头模块行进通过管道时，第一插头模块以第二模式的位置被排放到具有密封件的管道上，但是在流体旁路模式中没有配置夹具，使得被第二插塞模块移位的流体绕过第一个插头模块。然后将第二插头模块和第一插头模块密封地固定到管子上以隔离具有限制的管壁的一部分。

摘要： An apparatus for sealing an open end of a pipe includes an external clamp for frictionally being secured to the exterior surface of the pipe and an internal clamp for frictionally being secured to the interior surface of the pipe. The apparatus further includes a means for pressurizing the interior of the pipe.

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.

摘要： An apparatus for sealing a section of a pipe interior includes a clamp having a magnetic engagement means for axially positioning the clamp within the interior of a pipe and preventing relative axial movement there-between and a sealing plate securable thereto. Movement of the sealing plate against the clamp results in deformation of a resilient sealing member thereby forming a seal between the apparatus and the pipe. The apparatus can be used in conjunction with another, oppositely oriented apparatus or other sealing means to form a sealed space within the tube. Pressurization of the sealed space allows for a radial and/or axial force being applied to the sealed section of the pipe.
