Marine Ship Ballast Tank Anodes Aluminium Sacrificial Anode For Cathodic Protection

Marine Ship Ballast Tank Anodes Aluminium Sacrificial Anode For Cathodic Protection
English English Spanish Spanish Arabic Arabic

Description:

Sacrificial Aluminium Anodes are simple and economical way to protect the steel structure in seawater and fresh water environment.Upon proper installation that Aluminium anodes will performance efficiently and continuously without any attention for CP systems.The performance of Aluminum anode is affected by the chemical composition of the alloy.

Aluminum anode chemical composition type:

Al-Zn-In, Al-Zn-In-Cd, Al-Zn-In-Sn, Al-Zn-In-Si, Al-Zn-In-Sn-Mg, Al-Zn-In-Mg-Ti.


Advantage

Aluminum anode has lower driving potential and high current capacity ,they protect the equipment for a longer time.


Application:

Aluminum anodes are widely used on ship hull, ballast tank, harbor dock, offshore platforms, oil tank, Pipe in the seawater, etc.


Chemical compositions of hull Aluminum Anode:
1. CA-I General Aluminum Alloy Anode
2. CA-II High Performance Aluminum Alloy Anode
3. CA-III High Activation Aluminum Alloy Anode
4. CA-IV High Temperature Resistance Aluminum Alloy Anode
