A method for preventing pipe parts from being corroded by coating paraffin on surfaces of the pipe parts after manufacturing pipes parts using various copper alloys such as brass, bronze, etc. is provided. A method for preventing pipe parts from being corroded comprises: manufacturing various pipe parts including valves such as angle valves and ball valves, fittings such as elbows, T-shaped pipes and Y-shaped pipes, and pipes through casting, die-casting, forging, and cutting; dipping the pipe parts into a molten paraffin solution, and taking the pipe parts out of the molten paraffin solution; dewatering and drying the pipe parts coated with the molten paraffin solution for 5 minutes to one hour such that a paraffin coating layer as a thin transparent film is formed on surfaces of the pipe parts.
