In order to improve the service performance of oil pipeline for oilfield development, this paper takes Ф73×5.51 mm J55 oil pipeline as the substrate, and uses self-spreading high-temperature synthesis technology (SHS) to add 4wt%Nb₂O₅, 8wt% ZrO 2, 13wt% CrO₃, and 5wt% SiO₂ to the basic aluminum thermal system of Al+Fe₂O₃ (B component) as a new type of SHS material system, and prepares a new type of ceramic lined wear-resistant coated oil pipe (A component). Using SEM analysis, EDS analysis, XRD analysis, FTIR analysis and other analytical means to test the acid corrosion resistance, bonding strength, bending strength and crush strength and other properties, comparative analysis results show that: the corrosion resistance, bending strength, bonding strength and crushing strength of the ceramic lining layer prepared by component A are better than that of component B. The flow corrosion weight loss rate of component A coating and component B coating at 1200 h is 0.42% and 0.54%, respectively, which is better than that of J55 tubing substrate, and the bending strength of ceramic lined tubing prepared by component A is 15.9% higher than that of component B. Based on the observation of the slip position, the transition temperature between the strength of partial metallurgical bonding at the Fe-Fe interface and the mechanical bonding at the FeAl₂O₃ interface was determined to be about 200℃, with the mechanical bonding strength being greater than the metallurgical bonding strength at low temperatures, and the mechanical bonding strength being less than the metallurgical bonding strength at high temperatures. Both the bond strength and the crush strength properties of the ceramic lining layer showed a significant decreasing trend with increasing temperature.
