从中央科学研究院钢结构设计院和其他一些专门组织的技术文献中可以看出,带浮船的预制成半成品的 PBC—20000型油罐具有很高的技术经济指标,因此可以在各地区使用。这种油罐在石油贮运部门也得到广泛应用。然而,由于 PBC—20000油罐装有软密封的槽形浮船是向上敞开着的,因此在用于转运少量标准原油或石油产品的情况下,或当油罐接收主输油管送来的石油时,标准油罐总的可靠性下降。为此,最近又重新尖锐地提出:当发生气阻时以及油品或灭火液积聚到浮船表面上的情况下,如何选择避免浮船沉没到 PBC—20000
As can be seen from the technical literature of the Steel Structure Design Institute of the Academia Sinica and other specialized organizations, PBC-20000 prefabricated tanks with floating vessels have high technical and economic indicators and therefore can be used in various regions . This tank has also been widely used in oil storage and transportation departments. However, since the PBC-20000 tanks are upwardly open with soft-sealed tank-type pontoons, when used to transport small quantities of standard crude oil or petroleum products or when the tanks receive oil from the main pipeline, The overall reliability of the standard tank declines. To this end, recently, it has been pointedly pointed out again sharply how to avoid sinking the pontoon to the PBC-20000 in the event of an air resistance and the accumulation of oil or liquid fire on the surface of the pontoon
