The corrosion of a glass coating of pipelines in acidic, alkaline, and marine environments was studied. In an acidic environment the corrosion of a pipe coating is very small and the corrosion rate is practically non-existent. In an alkaline environment, initially the leach rate is very low and then sharply increases. In the range pH = 6 – 12, pipe coatings do not have high stability and active leaching of pipe coatings occurs. It was shown experimentally that during long-time operation very small scale deposits are observed on the surface of the glass coatings of pipes, but a significant layer of scale forms in pipes that are not glass-lined.

石油化工用管道玻璃涂层腐蚀和结垢的调查

研究了管道玻璃涂层在酸性、碱性和海洋环境中的腐蚀。在酸性环境中,管道涂层的腐蚀非常小,几乎不存在腐蚀速率。在碱性环境中,最初的浸出率非常低,然后急剧增加。在 pH = 6 – 12 的范围内,管道涂层不具有高稳定性,并且会发生管道涂层的主动浸出。实验表明,在长期运行期间,在管道的玻璃涂层表面观察到非常小的水垢沉积物,但在未搪玻璃的管道中形成了显着的水垢层。
