Method for internal pipe protection

摘要

The invention is a method and device for providing a protective coating for the inside of pipes, said method utilizing a device which is remotely actuated from outside said pipes. Specifically, the device comprises a memory metal delivery means, a corrosion resistant liner means, and a bonding means, said device expanding upon application of heat toward the inner wall of the pipe to cause the bonding means to flow progressively between the liner means and the inside of the pipe to thereby preclude air entrapment and to bond said liner means to the inside of the pipe.
