This document discusses the design of galvanic anode cathodic protection systems. It outlines some key advantages of galvanic anode systems, including that they do not require an external power source, have lower installation and maintenance costs than impressed current systems, and can provide protection in areas where power is unavailable. However, it also notes that galvanic anode systems have limited current outputs due to their small driving potential difference. The document provides information on selecting suitable anode materials and their specifications for efficient galvanic cathodic protection.
This document provides an overview and agenda for a presentation on modern cathodic protection for piping. It discusses corrosion basics, criteria for cathodic protection, design considerations for galvanic anode systems, and types of cathodic protection systems. The document uses examples to demonstrate how to design a cathodic protection system using galvanic anodes to protect an underground coated steel pipe over 20 years. It compares zinc, standard magnesium, and high-potential magnesium anodes in terms of current output, life expectancy, and cost.
Galvanic anodes provide cathodic protection to buried metallic structures using sacrificial anodes made of materials more electronegative than the structure, like magnesium or zinc alloys. The anode material corrodes to provide a protective current without an external power source. Selection involves analyzing performance, cost, and calculating requirements like anode size based on structure size, material properties, design life, and protection criteria. Installation and maintenance costs are generally low for galvanic systems.
This document discusses cathodic protection, which involves applying a small electric current to the surface of a metal structure to prevent corrosion. It describes two main methods: impressed current uses an external power source connected between the structure and an auxiliary anode buried in the ground, while sacrificial anodes rely on galvanic action between the structure and more reactive anodes. The principles of cathodic protection involve driving the structure's potential negative of its corrosion potential to inhibit the corrosion reaction while increasing the cathodic reaction. Proper design considers factors like protection potentials, current density, coatings, and avoiding over-protection.
1. Cathodic protection is used to prevent corrosion of oil well casings by making them negatively charged with respect to the surrounding soil. This protects exposed areas of the casing from corrosion.
2. Oil well casings differ from pipelines in that they are vertical, potentials can only be measured at the top, and connections are threaded instead of welded. Soil properties also vary with depth.
3. Cathodic protection only protects external surfaces in contact with the soil and does not protect internal surfaces of the casing or downhole equipment.

Corrosion is the gradual destruction of materials by chemical reaction with the environment, usually affecting metals. Cathodic protection is a method of corrosion control that protects buried or submerged metallic structures by supplying an external cathodic current to move the structure's electrochemical potential into the immune range. There are two main types of cathodic protection systems - sacrificial anode systems which use more reactive "sacrificial" metals to corrode instead of the protected structure, and impressed current systems which use an external DC source and insoluble anodes to supply current to the structure. Cathodic protection is widely used to protect structures like pipelines, storage tanks, ship hulls, and reinforced concrete.

This document provides an overview of galvanic corrosion. It defines corrosion and galvanic corrosion specifically. Galvanic corrosion occurs when two dissimilar metals are in contact, where the more active metal corrodes at an accelerated rate while the noble metal corrodes at a reduced rate. The document highlights how the difference in corrosion potentials between the metals determines the severity of galvanic corrosion. It also notes some methods to prevent galvanic corrosion, such as using galvanic coatings and controlling the surface area ratio between the metals. Videos are included to demonstrate galvanic corrosion procedures and examples.
This document discusses four main forms of corrosion: galvanic, crevice, pitting, and intergranular corrosion. It provides details on the mechanisms, examples, and factors that contribute to each type. Galvanic corrosion occurs when two dissimilar metals are in contact in an electrolyte. Crevice corrosion is localized corrosion in stagnant areas like joints or cracks. Pitting corrosion produces small pits on metal surfaces. Intergranular corrosion preferentially corrodes grain boundaries in metals. The document examines each type through definitions, diagrams, and real-world corrosion incidents.
