要約
(EN)
Provided are a copper-containing refrigerant pipe whose corrosion can be suppressed, a heat exchanger, and a method for producing a refrigerant pipe. A refrigerant pipe includes a pipe body including copper or a copper alloy and an anticorrosive film formed on the outer surface of the pipe body. The anticorrosive film is obtained by applying a coating agent to the outer surface of the pipe body. The coating agent contains one or more anticorrosive agents selected from the group consisting of (A) an organic sulfonate compound, (B) a polyhydric alcohol-organic acid ester compound, and (C) an aliphatic amine compound having 8 to 24 carbon atoms. When the coating agent includes an anticorrosive agent of (C) the aliphatic amine compound having 8 to 24 carbon atoms, (C) the aliphatic amine compound having 8 to 24 carbon atoms is included in an amount of 2.0 wt% or more and 10.0 wt% or less in the coating agent.
