The following could be done:
1. Checkfor the degradation of MEA and change it if required.
2. Use treated boiler water for make up.
3. Perform UT (preferably) or RT in the blistered as well as satisfactory areas. Interpretation to be done by levelIII holder.
4. Rerate your equipment from...
Dear givnoz
There are two factors governing the corrosion in SS:
1. Environment
2. Chemical composition.
If marteniste is present somehow in Austenitis SS, the corrosion resistance has to decrease in this area. Also this phase is brittle. As long as the protective oxide layer is in tact and at...
Dear Sir
You can use two component polyamide adduct cured epoxy painted carbon steel shell for the storage of dilute sulphuric acid. If the temperature is aroun 65-70 degree C, you can use GFRP (Glass Fiber Reinforced Olastic) tanks as well. Depends on your economics. The former is cheaper...
Hi
Usually the corrosion allowance for carbon steels is widely taken as 1.27mm. (Refer to any process plants designers pipe standards like Haldor Topsoe, Chiyoda, etc.) Take the life expextancy of equipment as 50 years. From these two values you arrive at an acceptable rate of 5mpy (Mils per...
