[MW:12497] Query regarding use of CS Fasteners and CS Blind Flanges for Hydrotest of SS Vessel

 Dear ALL,
 
Greetings.

Please refer below Client Specfication which quotes  ---
  
Hydrostatic pressure testing shall be performed with gaskets and bolting identical to those required in service and as specified on the data sheet. These gaskets may be used as service gaskets if the bolted joint is not disassembled after completion of hydrostatic pressure testing.
 
I believe as per the above requirment only SS Fasteners and Blind flanges shall be used during the hydrotest  of
 SS Vessel UNLESS Data Sheet/Drawing is allowing to use CS Fasteners and Blind flanges for hydrotest.
 
Please suggest.
 
Thanks & Regards
 
Asad Azmi
