Zinc anode cathodic protection for marine and offshore industry

 

Description:

 

The zinc anode has a variety of use in marine industry. Its application is limited at the temperature range below 60ºC or when the alkalinity is high. This is due to the polarity reversal occurred to zinc/ iron half cell under the above mentioned conditions. These anodes used for the protection of structures in numerous aqueous environments. Sacrificial anode is a protecting cathode for metal constructions in marine and harbor industries.its properties are in compliance with the requirement of the GB/T 4950-2002.

 

Specification:

 

Electro-chemical characteristics Open-circuit Voltage V Close-circuit Voltage V Actual Capacity(Ah/kg) Consumption rate kg·(A·a)-1 Current Efficiency  Dissolve Performance
Sea water(1mA/cm2) -1.09~-1.05 -1.05~-1.00 ≥780 ≤11.23 ≥95% The surface dissolve evenly&oxide drop easily
In soil(0.03Ma/cm2) ≤-1.05 ≤-1.03 ≥530 ≤17.25 ≥65%

Reference electrode: saturated calomel electrode(SCE)

Medium: arificial sea water, salt water or natural sea water; in soil used moist soil and filled up by back-fill material.

 
Application:
 

1. Interior of pipe handling corrosive waters and effluents.

2. Interior bottoms of oil storage tanks.

3. Double bottom areas of ship ballast tanks.

4. Bottom areas of cargo/ballast tanks of petroleum carriers.

5. Annulus space between outer steel casing and inner pipe of deep wells.

6. Can be used in marine and offshore industies, such as vessel, harbour structure, offshore engineering, submerged pipeline etc.

 

Feature:

 

All metals immersed in an electrolyte (for example sea water) produce an electrical voltage. When two unalike metals are in contact (electrically connected) they produce a galvanic cell (like a battery), with the less noble metal (for example a bronze propeller) forming the anode and the more noble metal (stainless steel shaft) forming the cathode. So we call this phenomenon as sacrifice anodes to protect cathode.
