摘要：
A pipe flange spreading tool is disclosed. The pipe flange spreading tool includes a pair of wedges and a retainer strap. Each of the wedges has a tapered end, and the tapered end is configured to be forced between two pipe flanges of a pipeline to separate the pipe flanges of the pipeline. The retainer strap connects the pair of wedges. The retainer strap is configured to be looped around the pipeline to retain the pair of wedges with respect to the pipeline during operation.
