Abstract
A pipeline breakaway mechanism is provided which includes an elbow in a pipeline and two clamps holding the pipeline to a structure such as a platform or another pipeline. When a strong pull is exerted on the pipeline, the pipeline is bent until it buckles around the first clamp; the first clamp then fails at a preset load, causing the pipe to bend around the second clamp and causing the previously formed buckle to straighten. This buckling and straightening of pipe causes the pipe wall to fracture at a load much smaller than its tensile strength.
