1) Magnesium Casting Anode
Grade: AZ63, AZ31, MGM1C
Main application: Sacrificed magnesium anode suitable applies in
the fields of anticorrosion. Such as: Oil, gas, water transmission
in underground or fresh water, underground cable, chemical,
communication, bay, watercraft and reservoir strobe.
2) Magnesium extruded anodes
Grade: AZ63, AZ31, MGM1C
Main application: Water heaere, water container, pre-polarization
of steel structure in seawater, gas pipe, anticorrosion of steel
and iron structure where high resistant and electrolyte (soil and
water) existed.
3) Ribbon Anode
Main application: Ribbon anodes are used for the cathodic
protections of sleeved pipings, tanks and pipe networks ad
grounding grids guarding against heavyy current interfereence. And
temporaly cahodic protection of pipings.
4) Aluminum Anode
Type: AL-Zn-In-CD AL-Zn-In-Sn Al-Zn-In-Si
Main Application: Aluminum anodes are suitable for the cathodic
protection for such metal structures as ships, machinery, offshore
engineering, harbor facilities, and pipings and cables in an ooze
corrosion environment.
5) Zinc Anode
Main Application: Zinc anodes are sitable for the cathodic
protection for ships machinery, offshore engineering and harbor
facilities in seawater and fresh seawater andd for pipes and cables
embeded in soil with cower resistivity.
6) High Silicon cast iron anode
Type: High silicon cast iron Cr-containing silicon iron
Main Application: It is widely aplied to the impressed current
cathodic protection of oil drilling platform at sea. Bried pipings
anad cables under ground.
