我国在针对重质油以及原油进行输送的过程中,如果说降低了输送过程中所呈现的温度,那么就极有可能会导致油品在其中出现凝固的现象,这对于输油单位本身来说,就是一种极其严重的损失。因此,必须要针对进行特殊液体输送工作的钢质埋地管道来进行防腐层设置,同时还要确保管道自身有着较为良好的保温效果,通过保温的方式,来确保管道内部所流动的液体不会由于温度等方面的因素而完全停止流动。本篇文章主要针对埋地钢质管道硬质聚氨酯泡沫塑料防腐保温层的检测评价技术进行了全面详细的研究,以期为我国的特殊管道发展研究工作作出贡献。
In the process of transporting heavy oil and crude oil in our country, if we reduce the temperature presented in the process of transportation, it is very likely to cause the oil to solidify in the oil transportation unit itself It is an extremely serious loss. Therefore, it is necessary to carry out anticorrosive coating for the steel buried pipeline for special liquid transportation work, and at the same time, to ensure that the pipeline itself has a relatively good thermal insulation effect, so as to ensure that the liquid flowing inside the pipeline will not Due to temperature and other factors completely stop the flow. This article is mainly for buried steel pipe rigid polyurethane foam corrosion protection and evaluation of the technology conducted a comprehensive and detailed study with a view to China’s special pipeline to contribute to the development of research work.
