Dear All,

Please see the attached photo for the undercut and advice if it is possible to repair this on PTEF lined vessel the vessel. The size is 2” NB and wall thickness is 2mm with inside PTFE lining of 4mm. We have imported this vessel from Germany but during 3^rd party inspection it is rejected because of this undercut. The working pressure of this vessel is only 3.5 bar and its successful withstood a hydro test pressure of 10 bar.

Now I request all the expert to please advice if we can repair this undercut if yes than please provide me some guideline or some procedure to carry out this repairing.

Thanks in advance for your kind help.
