From : Mr.M. S. Nimbalakar.

This refers to the discussion we had with you on 4th Aug. and your minutes of meeting dated 4th Aug.    

We are confirming all the points of the minutes of meeting except point nos.1 & 2 

We will be sending the revised quality plan with changes for your approval.  

LLE is designed for full vacuum inside.  Hence in the design calculations, external design pressure (equivalent to full vacuum inside) becomes the governing factor for the thickness.  For external design pressure, joint efficiency factor does not come into calculations.  Hence as per code, radiography is not required for the LLE.  So we suggest not to insist for radiography since LLE will be designed and fabricated as per code.
