    Fasteners and options for highly corrosive atmospheric environment

    Thank you for your informative response. I have used Denso wax tape before on large flanges. But I am not familiar with epoxy, Dow Corning 734 silicone, or other products. Other than Dow Corning 734 silicone, would you recommend any specific product for encapsulation? Thank you.

    Fasteners and options for highly corrosive atmospheric environment

    I would like to learn more about what mitigation measures are used in a highly corrosive atmospheric environment, such as off-shore applications. The original design uses galvanized steel, with some aluminum parts and stainless steel fasteners. I am thinking the HDG may not be enough for such a...

    close interval survey

    Thank you guys for your replies. How about discontinuous pipe then? Can CIS be performed if the pipe is not continuous? If not, why is that?

    close interval survey

    thank you very much, Steve. But in order to do what you said we are doing, I would imaging we need to move the connection of the pipe. For example, initially both half-cell and pipe are connected at location A0. Both the half-cell and the pipe connection should move to location A1, A2, A3 and...

    close interval survey

    I just stated working in cathodic protection industry and I am confused about the mechanism of close interval survey. Would someone help me or point some reference for me? Really appreciate your inputs. I understand that we try to measure the potential difference between the pipe and the soil...
