Zinc Ribbon Anode provide a very simple,cost effective,maintenance-free method of corrosion control for buried or immersed metals such as iron,Steel,Aluminium,Copper,etc.It is especially used for unattended application:those where other cathodic protection systems requiring monitoring and/or frequent maintenance cannot be possible.
Zinc ribbon anode can be used in fresh water, seawater environments, also can be used in underground structures.

Application
Our zinc ribbon anodes serve as a reliable solution for passive cathodic protection of metal structures operating in constrained spaces or high-resistivity environments. They are particularly well-suited for scenarios such as: underground carrier pipes housed inside protective sleeves; closely positioned pipeline grids; pipeline routes cutting through rocky, mountainous terrain; limited clearance between the inner and outer casings of oil/gas wells; the gap between the base of corroded legacy storage tanks and newly installed tank bottoms; and narrow spaces that demand a wrapped installation approach to safeguard steel structural components.
