摘要
随着我国滩海石油工业的迅速发展和上陆海底管线的兴建,滩涂区海土腐蚀性的调查研究就显得更为紧迫和重要,然而,目前国内仅在个别海区作过有关工作,国外虽在海土腐蚀性评价等方面作过一些工作(1974;Roger,1980;Karl,1981),但直接有关滩涂海土腐蚀性试验研究方面的报道甚少。
A corrosion testing of steel (A3 and API5LX52)was conducted in the beach soil of Tang-gu and Yangjiaogou situated in Bohai Sea coast for two years. The average corrosion rates of A3 steel and API5LX52 steel are 0. 035 - 0. 161mm/a and the pit corrosion rates are 0. 356 -1. 56mm/a. The corrosivenesses of beach soil are different according to the positions and depth of beach soils. The corrosiveness of Tanggu beach soil is stranger than the Yangjiaogou,and the - 1. 0m layer soil of Tanggu and Yangjiaogou have stronger corrosiveness than the -1. 5m layer and the surface layer.
