Common Types of Corrosion
Common Types of Corrosion
Corrosion - the deterioration of engineering materials, most commonly metals, by chemical interaction with their environment is an extraordinarily costly problem.
Stainless steel tubing is one of many areas where corrosion prevention can make a difference. Tubing systems are used for process and analytical instrumentation, hydraulic lines, and control and utility applications. The mechanical failure associated with corrosion - the escape of fluid or chemicals from tubing can result in an unsafe work environment, the release of harmful emissions, and in worst case scenarios, a situation that leads to a catastrophic system failure. Primarily, two forms of "localised" corrosion affect stainless steel tubing: pitting and crevice corrosion.
Corrosion Types:
- General (or Uniform) Corrosion
- Pitting Corrosion
- Crevice Corrosion
- Galvanic Corrosion
- Stress Corrosion Cracking
- Sour Gas Cracking or Sulfide Stress Cracking at High Hydrogen Sulfide (H2S) Partial Pressure
- Hydrogen Embrittlement
- Intergranular Corrosion
