Introducing hodic Protection – How Does hodic

The corrosion current of the anode material is the hodic protection current for the steel. The current flows through the electrolyte onto the steel, controlling its corrosion. The current returns to the anode in the metallic circuit. You may have heard the term ‘sacial anodes’. However, though this terminology describes the anode

Improved CP Anode Bed Performance - SAE Inc.

hodic protection (CP) anode beds are typically installed using carbonaceous backfill materials such as coal coke breeze, calcined petroleum coke breeze, or graphite particles.These carbonaceous backfills help reduce the contact resistance of the individual anodes in the anode bed by increasing the size of the anode.

Soderberg Electrode Paste is also called Anode Paste, Self-baking Electrodes Paste or Electrode Carbon Paste. It is produced from calcined petroleum coke (or calcined pitch coke, Electrically Calcined Anthracite Coal), calcined anthracite, coal tar pitch and other additional materials. It is used as conductor in submerged arc furnace under self

hodic Protection System in Oil & Gas Exploration

The hodic Protection is a method of that eliminates the corrosion of metals by the use of sacial anodes or the appliion of an electric current. It is a technique that has been known for 160 years, and is extensively applied to pipelines and tank farms, etc with great success.

hodic protection - SlideShare

Oct 28, 2012· For effective CP, the potential of the steel surface ispolarized (pushed) more negative until the surface has a uniform potential.Metals like (Zn,Al,Mg) are used for making anode because they have very lowelectrochemical potential as compared to steel hence more ‘active’.These metals act as anode and get corroded.For this purpose of

EP0085582A1 - hodic protection using conductive polymer

An impressed current hodic protection system for the reinforcing steel in concrete. Current is carried by a polymer concrete (16) which contains calcined fluid petroleum coke particles: the cured polymer concrete has a resistivity of less than 5 ohm-cm, which eliminates the need for large quantities of material and excessively high voltage in the system.

Anode - Wikipedia

An anode is an electrode through which the conventional current enters into a polarized electrical device. This contrasts with a hode, an electrode through which conventional current leaves an electrical device.A common mnemonic is ACID, for "anode current into device". The direction of conventional current (the flow of positive charges) in a circuit is opposite to the direction of electron
