Re: [MW:31634] Crack in vessel due to over pressure

Dear Muhammed,

If the welding has done correctly, the overpressure failure usually occurs after plastic deformation and it would be more or less obvious.

The appearance of the crack could give you a lot of clues...

Please provide us with a few high-resolution pictures of the vessel, the crack area and the crack itself...

Regards

Gents, 

Is there any option to find out if the vessel is cracked because of over pressure at site by mistake. 

If we perform a tensile test across the crack area, can we get any clue if grains are already permament deformed due to over pressure? 

Or is there any other metallogaraphic method can we employ? 

Reg, 

Ibrahim
