General causes of corrosion damage
The effect of various factors on corrosion damage is as follows:
Row of Effective Agent in Destruction
Effect on destruction(in term of percentage)
design, material selection and process 36%
Lack of necessary recipes 16%
Human error 12%
poor inspection 10%
Layout, installation, and poor coordination 14%
Unwanted Unwanted Forecasting 8%
other items 4%
Design, material selection and process
As indicated in the table, wrong design has the greatest contribution to destruction.
Important design issues include:
Choosing the right material according to temperature, environment and …
Determine the dimensional characteristics according to the required capacity and variables such as pressure and volume
Considering the components of force and torque
Failure to comply with any of the above will create a driving force in the direction of destruction.
Lack of necessary instructions
Instructions to be followed after design and construction are:
Instructions for correct installation
Operation and process recipes
For example, one of the things that needs to be followed is to know the amount of preservative chemicals and the monitoring of water.
– Design stages of construction, installation, maintenance and maintenance
– Technical inspection
– Unskilled or untrained manpower
Layout, installation and poor coordination
For example: Changing environmental conditions is one of the major causes of unforeseen circumstances in design issues.
Items such as fluid speed, insulation, etc. have a significant impact on this degradation.
