As a main offshore engineering structure, steel pipe pile is very important because it is immersed in seawater for a long time. Sacrificial anode cathodic protection of steel pipe pile is a kind of protection method to control metal electrochemical corrosion.
Port wharf refers to the steel and some reinforced concrete harbor facilities and structures. They are corroded by water medium and humid atmosphere, which makes the structure perforated, which seriously affects the safe use of port and wharf. Therefore, effective anti-corrosion measures must be taken.
According to the scope of protection, the full protection and local protection of the underwater parts of the ship should be treated differently. When the local protection is implemented, because the water flow speed is very fast and it is in the inflation state, the local protection can also be extended to the bow of the ship, but the bow is also under the influence of high water flow speed. Because the mechanical damage of the coating often occurs in the bow and middle of the ship, it is more and more important to implement complete protection by sacrificial anode or forced current method.
Because of the required protection current demand and current distribution, it is impossible or uneconomical to implement cathodic protection on ships without coating. If cathodic protection is implemented, marine organisms will adhere to inert copper in natural corrosion. Therefore, partial or all aluminum alloy or stainless steel hull must be subject to cathodic protection because they are prone to crevice corrosion under the coating.
Shandong Linyi Bosi conductive materials Co., Ltd. is a high-tech enterprise specializing in the production of MMO flexible anode, conductive polymer flexible anode and titanium coated anode, mainly providing cathodic protection technology, engineering design, installation and technical services.
