3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
The content of iron ions in water mass (mg/L) of water per unit volume usually indicates iron ions, may indicate corrosion pipeline system
Activity.
3.2
The water content of manganese ions, mass (mg/L) of water per unit volume is usually expressed manganese ions.
NOTE. ferroalloy materials for oilfield downhole equipment in the manganese content is generally 0.5% to 1.5%. So if all of the iron ions and manganese ions are rot
Erosion caused by water instead of the original output, the share of output of manganese and iron ions in water is about 100.
3.3
Installed on both ends of the main channel or bypass flanged short pipe length is generally 0.3m ~ 1m. Can be periodically removed for internal
For detection of the piping system to obtain information corrosion. Short tube material should be consistent with the main pipe material.
3.4
Applying an electric field in a short tube pipe metal loss in the pipe wall due to corrosion caused by the electric field changes, the change of the electric field measurements
To calculate the change in the corrosion of pipelines.
