随着中国经济的高速发展,石油和成品油的需求剧增。我国已成为石油进口大国,石油已成为国家重要的战略物资,它直接关系到我国的经济发展、社会稳定和国家安全,大型立式钢制储罐是石油化工行业非常重要的储运设备。目前我国大型储罐的施工建设进入了一个新的高速发展期,正从10×104m3向20×104m3大型化发展,罐体钢板也从原先的进口向国产化发展。大型原油储罐建造的工艺方法,对油库质量安全及工期具有决定性意义。本文以中国石油广西钦州100×104m3原油商业储备库工程4座15×104m3外浮顶原油储罐建造为例,介绍15×104m3外浮顶原油储罐从罐底、罐壁、浮顶及附件等施工技术。总结国产15×104m3外浮顶原油储罐建造施工技术,为国产大型储罐建造发展提供借鉴和参考。
With the rapid development of China’s economy, the demand for oil and refined products has soared. China has become a major oil importer and oil has become an important national strategic material. It is directly related to China’s economic development, social stability and national security. The large-scale vertical steel storage tank is a very important storage and transportation equipment in the petrochemical industry. At present, the construction of large-scale storage tanks in China has entered a new period of rapid development, from 10 × 104m3 to 20 × 104m3 large-scale development, the tank plate from the original import to the localization of development. Large crude oil tank construction process technology, the quality and safety of oil depot and construction period of decisive significance. This paper takes the construction of 4 15 × 104m3 external floating roof crude oil storage tanks in the 100 × 104m3 crude oil commercial reserve project of Qinzhou, Qinzhou, Guangxi as an example to introduce the construction of 15 × 104m3 external floating roof crude oil storage tanks from tank bottom, tank wall, floating roof and accessories Other construction techniques. The construction technology of domestic 15 × 104m3 floating roof crude oil storage tank is summarized, which can provide reference and references for the construction of large domestic tank.
