Dear SSM,
Following defects may be found during a detailed inspection:

1. Corrosion inside
2. Reduction in shell thickness
3. Welding joint cracks
4. Welding joint leakage
5. Safety valve non-functioning
6. Auto drain not working
7. Pressure gauge indication not proper

Maybe the above will help you!

Dear Raghu,
Thanks for the attachments. Surely good study material. I will read it when I get time. Thanks and keep on sharing. Let's keep this forum alive.

Dear SSM,
The visual defects of an unfired pressure vessel can be:

1. Rusting of the plate used.
2. Quality of the weld joint.
3. If marked, you can see when it was last tested.
4. Functioning of the drain valve.
5. Functioning of the drain valve.

After these visual checks, you can decide the next line of action.

Thanks to Raghu and Dipil for your posts on this thread.

Thanks & Regards,
Sudhir
