The invention discloses a pipeline steel wire processing technology for improving stress corrosion performance of pipeline steel wires, and relates to the processing technology of prestressed pipelinesteel wires. The purpose is to solve the problem that the stress corrosion performance of existing pipeline steel wires is poor. Steel wire rods are subjected to acid pickling and phosphating in an acid pickling groove, conveyed into a hot wind drying furnace to be heated to 200 DEG C and subjected to one-hour drying treatment, and hydrogen atoms entering steel in the acid pickling and phosphating process are removed; a drawbench is used for wire drawing, in the wire drawing process, the drawing speed is controlled to less than 2 m/s, cooling is strengthened, the temperature of a steel wire demolding port of a drawbench mold is below 120 DEG C, the temperature of a steel wire mold inlet is below 40 DEG C, and stress ageing is eliminated; the angle is matched with the compression rate in aworking area of the drawbench mold, and according to the compression rate, the length of the working area of the mold is controlled. The processing technology has the advantage that the hidden trouble of stress corrosion cracking of the pipeline steel wires is eliminated.
