Localized Corrosion
Localized corrosion targets one area of the metal structure. Localized corrosion is classified to three types
Pitting: When a small hole or cavity forms in the metal. This small area of deterioration can result in failure.
Crevice Corrosion: This is similar to pitting where it will happen in a small part of the metal. This often happens under stagnant micro-environments.
Filiform Corrosion: This happens under plated or painted surfaces, usually when water gets under them. This can spread and cause failure.
De-Alloying
The selective leaching of a specific element in an alloy. The most common type is the de-zincification of unstable brass.
What is Corrosion?
There are many different types of corrosion. It is known as metals chemical deterioration.
General Attack Corrosion
This is the most common type of corrosion and is caused by a chemical or electrochemical reaction that then deteriorates the entire exposed surface of the metal. This can cause the metal to deteriorate to the point of failure.
Fretting Corrosion
Occurs as a result of repeated wearing, weight, and vibration on an uneven rough surface. This causes pits and grooves on the surface.
Galvanic Corrosion
This happens when two types of metal corrosion occur when two different metals are located together in a corrosive electrolyte.
Environmental Corrosion
This results from a combination of environmental conditions affecting the metal. These can all be affected by chemical, temperature, and stress-related conditions
Flow-Assisted Corrosion (FAC)
Happens when the protective layer of oxide on a metal surface is dissolved or removed by water, exposing the underlying metal to more corrosion and causing failure.
Intergranular Corrosion
This is a chemical or electrochemical attack on the grain boundaries of a metal. It most often occurs from the impurities in the metal which tend to be higher in concentration near grain boundaries.
High Temperature Corrosion
Can happen during combustion, form compounds with a low melting point. These compunds are very corrosive towards metal.
We have developed a simple solution that will mitigate corrosion and extend the runtime of your downhole equipment
S73 Downhole Sacrificial Anode
The S73 is designed as a 4 foot 2-7/8" EUE sacrificial anode made up of specific aluminum alloy that becomes anodic within an electrolyte and protects the more noble metals. The more active metal (S73 Sacrificial anode) within the electrolyte corrodes and is consumed at a faster rate while protecting the more noble metals (Downhole equipment) from corrosion concerns. The S73 sacrificial anode is installed downhole below the no-turn tool and is simple and effective product that will help clients eliminate premature failures and extend the operating life of the downhole assets.
PJ89 Downhole Sacrificial Anode
The PJ89 is designed as 6 foot x 3-1/2" EUE sacrificial anode that meets all required API standards. These sacrificial anodes are fabricated in a specific aluminum alloy coating allowing it to operate anodically within an electrolyte and provide protection to noble metals. The more active metal (PJ89 Sacrificial anode) within the electrolyte corrodes and is consumed at a faster rate while protecting the more noble metals (Downhole equipment) from corrosion concerns. This product is also designed specifically to be installed downhole where clients may require more aggressive protection in a localized area of concern. This product effectively mitigates corrosion concerns while extending the life of all associated downhole assets. (Patent pending)
All products manufactured by Source Solutions can be adjusted in sizing in order to meet specific client needs depending on a variety of factors.
