    Aluminium anode in Seawater

    Hi, For a seawater storage tank i am using a sacrificial Aluminium anodes system to protect the internal submerged surface. Is it normal that when i calculate anode life the result is about 2 years (depending on the dimension of the chosen anodes). according to the calculation formulas and due...

    Isolating Kit requirement

    Hi, For a short length of buried pipeline, I will use a galvanic cathodic protection system by connecting a Mg anodes. Is it necessary to place an isolating kit on the extremity of the pipe or this is not required because it is not a ICCP system.

    CP Attenuation

    Hi, For the cathodic protection design of 200 Km of pipeline i used the the following formula to calculate the protected length: L_max=Acosh[(Es)/(El)]/α the L calculated is the total protected length or the length of protection in one direction from the draining point??? meaning if my draining...

    cathodic protection design

    Hi, I will design a cathodic protection system for an already existing tank with a 100m of diameter, under the tank at 500mm depth a layer of PE sheet is spread entirely so - because it's not a new tank i can't use the grid anode under the tank - because of the PE layer I can't use the beep...

    Waard Model for corrosion allowance

    Hi! Normaly,the waard model is for pipeline in wet conditions, but Is it possible to use it for the calculation of the corrosion allowance for a tank or a scrubber for exemple Thank you

    NACE standards for a pump

    I have a water pump with 160ppm of H2s and around 200000ppm of chloride. The pump is in duplex. Is this compatible with the NACE requirement
