Blind thickness for hydrotest

[Ajay Paul]

Dear Experts ,

        i need some clarification 

i need 50mm thickness blind for hydrotest,but i dont have that thickness so can i use welded  30mm+20mm blinds for it?

Pls. suggest .

Usually (as per code practice too), defined blind to be used. Sometimes plate blinds allowed with inspector permission but thickness can’t be achieved using layers. 

Thanks & Regards,
