沿海地区大型储罐工程海水充水试验防腐蚀技术

Anti-corrosion Technology in Hydrostatic Testing Using Sea Water for Large Oil Terminals in Coastal Areas

近年来,国内开始在沿海地区兴建大型石油储罐工程,在整个工程中,防腐技术应用是否得当关系着工程的使用寿命以及总体成本,是整个工程非常重要的一个环节。以大连中石油国际储备库北区工程为例,对该项防腐技术的具体应用流程进行了详细的论述,介绍了在储罐充水试验中应用海水介质,采用了铝制一次性牺牲阳极,配合铝合金阳极块的防腐技术,不仅能保证充水试验效果,同时也有效地降低了工程成本。

In the last several years, large oil terminals began to be built in the coastal areas in China. In the project implementation, the successful application of anti-corrosion technology, which is an important part of the project, has a direct impact on the service life of the project and total project costs. On the basis of the north area project of Dalian International Oil Reserve Terminal of Petrochina, the project and is briefly described and specific application of anti-corrosion technology is detailed. In the project, sea water is used for the hydrostatic testing of tanks, Alsacrficing anode is installed together with A1 alloy anodes to prevent corrosion. The characteristics of the technology are summarized. The practice shows that the application of this technology has not only ensured the good results of hydrostatic tests but also reduced the project costs.
