CATHODIC PROTECTION DETAILS

Cathodic Protection has long been recognized as a vital contribution to the durability of buried or immersed structures, such as pipelines and well heads. Frequently the structures to be protected are located in remote areas that lack a reliable DC Power Source.

Solar Power is the ideal solution and and TDH Visions has all the custom designed tailored systems to offer with best technical reliability.

It is a technique to control the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. It is a method used to protect metal structures from corrosion. Cathodic protection systems are most commonly used to protect steel, water/fuel pipelines and storage tanks; steel pier piles, ships, offshore oil platforms and onshore oil well casings.

A side effect of improperly performed cathodic protection may be production of molecular hydrogen, leading to its absorption in the protected metal and subsequent hydrogen embrittlement. Cathodic protection is an effective method of preventing stress corrosion cracking.
