Estimation of remaining life of pressure vessels

Estimation of remaining life of pressure vessels

Estimation of remaining life of pressure vessels

I want any informations about the methodes of estimating of the remaining life of pressure vessels in oil field industry and the convertion tables of steel from AFNOR to ASTM. These steel are destinated for the manufature of pressure vessels.

RE: Estimation of remaining life of pressure vessels

One method is to examine the corrosion rate  (UNIFORM Corrosion).

1. determine the material thickness (use ultrasonic techniques) at several locations, heads, shell, nozzles etc.

2. From the Original design drawing get thickness.

3. Determine what the losses are. mills per year (CORROSION RATE)

4. Determine the required thickness ASME SECTION VIII Div 1
   type of calculations

5. Estimated life in years is (Measured thickness - Required Thickness)/ Corrosion Rate

For pitting corrosion you need to measure the pit depth

The assumption is that the process does not change.  Any change in the process can have a dynamic effect on Corrosion rate.

Hope this help.
