Where are anodes for cathodic protection systems installed?

Where are anodes for cathodic protection systems installed?

Deep Anode Bed Installation Deep anode beds are most often used for the protection of well casings and pipelines, and normally range from 150-700 ft. in depth and consist of 10-20 anodes.

Where do you connect the anode?

The process is called electrolysis, and the two wires or plates dipping into the electrolyte are called electrodes. The electrode which is connected to the positive terminal of the cell or battery is called the anode. The electrode which is connected to the negative terminal of the battery is called the cathode.

How is an anode wire attached to the piping?

Two anode connections, for bonding to the pipe, should be attached to each bracelet half-shell. Electrical connection to the pipeline should be by means of four 16 mm2 cables per anode to be thermit welded to the pipeline after anode installation.

What are the requirements of a sacrificial anode?

There must be a return current path for the electrons to flow from the anode to the material it is protecting (being in physical contact is the usual path) and an electrolyte (water, humidity) to convey the electrons. Sacrificial anodes generally come in three metals: magnesium, aluminum, and zinc.

How long does an anode bag last in a metal underground tank?

~Without proper protection, a tank is vulnerable to corrosion, which results into a possible leak. ~According to the NFPA 58 LP-GAS codes, this MUST be done in intervals not to exceed 36 months. ~Depending on your soil type, these anode bags could be consumed in as little as 6 years.

Can you have too many anodes?

Over zincing happens when there is too much anodic protection. Having an excessive number of sacrificial anodes installed on your boat can lead to unintended consequences.

How is sacrificial anode calculated?

(6.23) and (6.24) are the initial and final current outputs for the individual anodes….Calculation of anode number.
