Abstract

DC60 (25/10/55) It is intended to achieve the effect of inhibition of further amplification of electrolyte corrosion (electrolytic corrosion) by aluminum or aluminum alloys formed by The Copper ions are propagated into connecting tubes made of aluminum or aluminum alloys. Copper ions are propagated through condensed water. And stay in a small space Between thermal insulating materials And connecting pipes in gas pipes 30 and fluid pipes 40 of the connecting pipe unit 20, connection 37 and 47, where aluminum pipes 31 and 41 (first refrigerant pipe Refrigerant tubes made of aluminum or aluminum alloy) and copper tubes 32 and 42 (two refrigerant tubes: refrigerant tubes made of copper or copper alloy) are connected to each other accordingly. Order Placed in the agreed part of the aluminum pipe 31 and 41, the connecting pipe 20 units were covered with a Thermal Insulation 60 Anti-corrosion treatment is applied to aluminum pipes 31 and 41 that are covered with heat insulating material 60:
