| 摘要 |
The present invention is a flanged connection repair device and method for flanged pipe joints and the like that produces axial compression against the flanges of the joint so that the flange bolts may be removed and replaced, while simultaneously producing radial pressure on the sealant between the flanges, mechanically and radially compressing the sealant into the joint, directing the sealant around the full perimeter of the flanged joint. By providing both axial and/or radial compression the invention stops leaks in the pipe without interrupting the use of the pipe, duct work, and the like, and can be used permanently or temporarily, repeatedly, and under a variety of conditions including moderate to high internal pressures, vacuums, and temperatures.
