Document Type and Number:
WIPO Patent Application WO/1998/034997
Kind Code:
A1
Abstract:
A method for repairing and/or reinforcing a bulkhead for a bulkhead type heat exchanger having a bulkhead formed of a permeable material comprising the steps of supplying a gas (G-1) containing a metal or/and a metallic compound to one side of the bulkhead, supplying to the other side thereof another gas (G-2) containing a reaction gas adapted to react with a metal or/and a metallic compound to deposit a solid metallic compound, said gas (G-1) and said another gas (G-2) being caused to reach the inside of the bulkhead, and then causing said gas (G-1) to react with said another gas (G-2) so as to deposit a solid metallic compound inside the bulkhead , thereby repairing and/or reinforcing the bulkhead of the bulkhead type heat exchanger.
