Underground Pipeline Protections
In the modern age of Industrial world, the oil refineries, petroleum products, and
petrochemicals form the major part of the industrial set-up all over the world. It is
often economical and practical to carry the liquid and gaseous products through
pipe-lines rather than by tankers over long distance. Passing through land, rivers,
sea, mountains crossing other services like roads, railways, transmission lines,
underground Pipes/Cables etc. This pipelines passing through soils which can be

billion has been lost to the Iraqi government due to unavailability of increased
control in its ability to stop corrosion completely, but it remains within the choice of
protection of steel piping or any other buried metallic structure, to extend their
iron or iron - base alloys with formation of corrosion products consisting largely of
hydrous ferric oxides. Nonferrous metals, therefore, corrode, but do not rust.
Corrosion can compromise the safety of operating equipment by causing failure. For
example, pressure vessels, boilers, metallic containers for toxic chemicals nuclear
power plants and for disposal of nuclear wastes. if the current is considered to flow
current enters it from the electrolyte The ideal design for a cathodic protection
system is the one which will provide the desired degree of protection at the
minimum total annual cost over the projected life of the protected structure.The
prevention of corrosion with cathodic protection is not new; the technology has
existed for over 189years. In 1824, Sir Humphrey Davy used cathodic protection to
papers to the Royal Society in London, in which he described how zinc and iron
anodes could be used to prevent the corrosion of copper sheathing on the wooden
