Re: [MW:24371] RE: 24361] Flange Buttering

Hai brother, 

  It's correct I have suggested same .. but my client told me to do buttering inside flange to close gap between pipe and flange due to ovality 

 Now my question is there is any code allow to do buttering at flange 

If yes means .. there is heat treatment necessary for that 

Thank you for your reply 

Best regards

Hi Friend,

Instead of flange buttering and re machining you can go for a layer build up on the pipe, and particularly for your case pipe has ovality, then as per the gap positions you can deposit single layer or multiple layer and have a proper grinding to give proper fitup to flange.
