Method for determining anti-corrosion layer of sulfur-proof oil pipe

The invention relates to a method for determining an anticorrosive coating of a sulfur-proof oil pipe, which comprises the following steps of: preparing a plurality of test steel sheets which are made of the same material as the sulfur-proof oil pipe; anti-corrosion layers of different preset styles are formed on the surfaces of the different test steel sheets; preparing weighted acid simulation liquid with set density; putting the test steel sheet on which the anticorrosive coating is formed into the simulation liquid, putting the simulation liquid into a reaction kettle, and sequentially carrying out weighted acid weightlessness corrosion tests on the test steel sheet at different set temperatures; and carrying out reliability evaluation and economical efficiency evaluation on the test steel sheets subjected to the corrosion test one by one, and selecting the corrosion-resistant layer with the optimal style as the corrosion-resistant layer of the sulfur-proof oil pipe. 本发明涉及一种防硫油管的防腐层确定方法，包括：制备多个试验钢片，所述钢片的材
