NOVELTY - The method involves selecting a steel material with high-corrosion resistance. A stirrer is utilized to soak an activating liquid in a steel pipe. The steel pipe is cleaned after soaking. A passivation device is utilized to passivate a surface of the steel pipe. The steel pipe is polished and passed by a grinding machine. The steel pipe is coated and air-dried by using a coating device. The steel pipe is welded by an electric welding machine. The coating device is provided with a spraying pipe. The raw material of steel material with high-corrosion resistance has: 0.12-0.22 wt.% carbon, 0.05-0.08 wt.% tin, 0.8-1.1 wt.% manganese, 0.06-0.16 wt.% chromium, 0.05-0.09 wt.% antimony, 0.11-0.15 wt.% yttrium, 0.01-0.18 wt.% vanadium, 0.13-0.17 wt.% molybdenum, 0.001-0.005 wt.% boron and iron (remaining amount). The coating has: 5-45 pts. wt. epoxy resin, 1-3 pts. wt. graphene, 15-25 pts. wt. phosphate, 45-60 pts. wt. titanium dioxide, 1-3 pts. wt. anti-settling agent and 8-20 pts. wt. xylene. USE - The method is useful for processing stainless steel pipeline with high-corrosion resistance. ADVANTAGE - The method can fully paint the inner and outer walls of the steel pipe, so as to fully adhere the coating and the inner and outer wall of the steel pipe, and enhance the corrosion resistance of the steel pipe. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the high-corrosion resistant stainless steel pipeline processing method (Drawing includes non-English language text).
