An apparatus for the emergency capping of pipes and wells is described. The apparatus uses a form of physically deformative valving for emergency closure of pipes and wells. An active magnetic field augmented theta pinch or zeta pinch apparatus causes the pipe or well fixture to collapse or otherwise deform into itself, thus shutting off the flow of material to prevent the environmental damage that may result if the material is a hydrocarbon such as crude oil natural gas, or the like. The apparatus can be rapidly deployed in response to a situation such as a catastrophic failure of a pipe or well. |
