[MW:28743] Piping ID chamfer mark in RT Films

Hi Experts,

The piping pre fabrication work going in HRSG piping , in which it has been found that some of the 6" pipe to elbow welding for downcomer are not satisfactory. 


When investigated it was found that pipes, which has been supplied, there are some tool mark in inner surface(refer photo).


 When the thickness measured there is a reduction of 1.25 to 2 mm in thickness and in radiography a dark clear linear indication.


Whether it's acceptable, if its acceptable means suggest code reference 

or we have cut and re-weld


Regards

G Mohanraj
