Test Station Cathodic Protection
Test station cathodic protection is suitable for cathodic protection of buried metal pipelines in different industries such as natural gas, liquefied petroleum gas, petroleum, refined oil, artificial gas, chemical industry, water conservancy and water supply, etc.
-
Zinc Alloy Cathodic Protection
Zinc alloy sacrificial anode is based on electrochemical principles, it uses the more active electrochemical properties of zinc to prevent the corrosion of other metals. When the zinc alloy sacrificial anode is in contact with the metal to be protected, it will voluntarily oxidize and transfer the corrosion reaction of the metal to itself.
-
Aluminum Alloy Cathodic Protection
aluminum alloy anodes are Al-Zn-In system and Al-Zn-Hg system anodes, which are suitable for cathodic protection of structures in seawater, such as ships, harbor industry and marine facilities, seawater cooling water system and storage tanks sedimentation water parts.
-
Magnesium Alloy Cathodic Protection
Magnesium alloy sacrificial anode provides cathodic current from magnesium alloy anode material body through soil, water and other electrolytes to the protected body, such as steel structure, so as to make the protected steel structure cathodic polarization and realize cathodic protection.
