The inner walls of oil and gas pipelines are eroded and corroded by the medium, with an annual corrosion rate of 0.3mm. Traditional pipeline inner wall anti-corrosion coatings (such as epoxy coatings) have a lifespan of only 3-5 years and require frequent pipeline replacement or inner wall repair. This not only incurs high costs but also affects the efficiency of medium transportation. The Daokedao laser cladding equipment has developed a dedicated annular cladding mechanism for repairing the inner wall of pipelines. It can perform 360 ° seamless cladding on the inner wall of pipelines with a diameter of over 150mm. The thickness of the stainless steel coating is uniform, with a density of 99.8% and a corrosion rate reduced to 0.01mm/year. A Russian oil company applied this technology to the repair of the inner wall of a 50 kilometer long crude oil pipeline, resulting in a 40% increase in the smoothness of the pipeline wall, a 5% decrease in crude oil transportation resistance, and an increase of 30000 tons in the annual transportation volume of a single pipeline. At the same time, the expected service life of the pipeline has been extended from 5 years to 30 years, and the leakage rate has been reduced from the original 5% to 0.5%, reducing oil leakage losses by more than $1 million per year and saving costs of over $20 million over the 30-year lifecycle.
