Aluminum alloy sacrificial anodes for anti-corrosion in ocean engineering. Manufacturer of steel pipe aluminum anodes
The corrosion of the inner wall of the bottom of crude oil storage tanks and sewage tanks is mainly due to electrochemical corrosion and bacterial corrosion caused by the sedimentation of crude oil and sewage. Moreover, the sedimented sewage at the tank bottom has a relatively high salt content (mainly S2-, Cl-, HCO3-, Na+, Ca2+, etc.) and a relatively high temperature, so its corrosiveness is relatively strong. Currently, the sacrificial anode method is commonly used for the cathodic protection of the inner wall of the tank bottom. This method is safe and reliable for the storage tank, does not require special personnel for management, and has a good protection effect. Usually, the materials used as sacrificial anodes include magnesium and magnesium alloys, zinc alloys, aluminum alloys, etc. The anode blocks are evenly arranged on the inner wall of the storage tank, and the steel plate is directly welded to the anode blocks.
Characteristics of the sacrificial anode protection method:
a) Fast and simple construction, without corrosion interference.
b) Low input cost and strong economy.
c) Safe and reliable, without the need for special personnel for management.
d) Remarkable protection effect.
According to the situation of the medium inside the wall, aluminum alloy anodes or magnesium alloy anodes can be selected as the anodes. When using sacrificial anode protection for the inner wall, attention should be paid to the influence of temperature. In a water medium environment at 40~70℃, magnesium anodes are not suitable because of their too high corrosion rate.
Calculate the required number of anodes according to the protected area, protection period, and medium resistivity, and select the anode specifications and shapes. The anodes are evenly distributed in a ring shape on the tank bottom plate, and the anode brackets are welded to the bottom plate. Sacrificial anodes are easy to install, and when the anode is consumed to 85% of its initial weight, it can be replaced during the tank cleaning opportunity.
Aluminum alloy sacrificial anodes are mainly used in anti-corrosion of offshore engineering. These anodes can work effectively in relatively pure seawater with high-speed flow. Therefore, as long as a suitable alloy is selected, the passivation phenomenon rarely occurs. They are light in weight, which is especially suitable for the usage requirements of 20 - 30 years.
