内浮顶油罐输油管路改造方法

Method of oil piping reconstructing for inner floating roof tanks

内浮顶油罐输油管路胀油管的安装不同于拱顶罐胀油管的安装。原内浮顶油罐输油管路中在罐前第二道阀门处并联一小口径单向止回阀,在收、发油过程中发现罐间有窜油问题,解决的办法是将单向止回阀改为弹簧压力阀。

The installation of expansion oil pipe of inner floating roof tank oil piping is different with that of dome roof tank oil piping. We restructure the inner floating roof tank oil piping by connecting a small - bore one - way cut off valve parallel with the secondary valve in the front of tank. However, we find the mixing problems when input and output oils. We later solve this problem by change the one- way cut off valve to spring pressure valve.

Xu Rui Abstracts: Of the major factors that have impacts on safety of depots and gas stations, two aspects such as lightening - proof design and grounding design are discussed.
