Problems solved by technology

In 2008, the sacrificial anode method was used to temporarily protect the 100,000 cubic meter oil storage tank during the seawater pressure test at the Dalian National Petroleum Reserve Base. The consumption during the pressure test is very large. According to the protection current density of 150 mA/square meter and the sea water pressure test

Abstract

The invention discloses an anticorrosive device of an oil storage tank during testing seawater pressure, comprising a potentiostat. A cathode cable wire induced from the potentiostat is connected to the soleplate of the oil storage tank; a zero position cathode connecting wire in a reference signal wire induced from the potentiostat is connected to the soleplate of the oil storage tank; a signal reference electrode wire in the reference signal wire induced from the potentiostat is connected to a signal reference electrode installed on the oil storage tank body; and the anode cable wire induced from the potentiostat is connected to auxiliary anode of mixed metallic oxide installed in the oil storage tank. The invention not only can effectively prevent the oil storage tank from being corroded during testing seawater pressure, but also can recycle equipment such as the potentiostat, the reference electrode, the auxiliary anode of the mixed metallic oxide, and the like, thereby reducing cost.

Description

technical field [0001] The invention relates to an anticorrosion device for an oil storage tank, in particular to an anticorrosion device for an oil storage tank during a seawater pressure test. Background technique [0002] At present, after the installation and welding of domestic oil storage tanks, in order to check the construction and installation quality of the oil storage tanks and the settlement of the oil storage tank foundation, fresh water is often used as the pressure test medium for pressure test tests. But in the sea or coastal areas, fresh water resources are very scarce, so more and more oil storage tank projects consider using seawater for hydraulic tests. Since seawater is much more corrosive than freshwater, corrosion protection of the storage tank body must be considered during seawater pressure testing. In 2008, the sacrificial anode method was used to temporarily protect the 100,000 cubic meter oil storage tank during the seawater pressure test at the ...
