Method e.g. for sealing leaks in large steel tanks and piping, involves sealing leaks of ferromagnetic objects and provides seal to set up leakage by permanent magnetic field

摘要

The method involves sealing leaks (1) of ferromagnetic objects (2) and provides a seal (3) to set up a leakage. The leak is sealed by providing a device to seal with a sufficient holding power such as provided by a permanent magnetic field. The magnetic field is provided from a permanent magnet (4). An independent claim is included for a device for sealing leaks.
