[MW:13571] Clad Dish End / Repair / ASME CODE SEC VIII Div 1

Dear All,
 
Is it mandatory to request a Partial Data Report(PDR) signed by ASME A.I from the Contractor who manufactured Dish End for the Pressure Vessel?
Actually the Dish End we requested was an Explosion bonded Clad Dish End, but dish end manufacturer found some repair on the clad portion and intent to do repair with Approved WPS/PQR.
 
The Service is LETHAL and the Final Vessel will be subjected to Heat Treatment  as per UW-2.
 
Whether we can accept this Dish End without a PDR as we are the sole responsible manufacturer of Pressure Vessel?
 
Please let me know the relevant Records/Reports needed as per ASME Sec VIII Div 1 to be instructed to our Sub contractor while deliverying this Dish End and the Code reference.
 
Looking forward all your postive reponse ASAP...
 
Thanks & Regards
Vino -Doha, Qatar
