Section VIII Div 1 - UG-84 (i)

Section VIII Div 1 - UG-84 (i)

Section VIII Div 1 - UG-84 (i)

(OP)

Under "Vessel (Production) Impact Tests Plates" (UG-84 (i) of Section VIII Div 1), there is the following statement about the materials used to make the test plate:

"The vessel impact test plate shall be from one of the heats of steel used for the vessel..."  

What's a valid interpretation of this?  That if the vessel is made from SA-105 and SA-516 Gr 70, the production test plate could be made from just the same heat of SA-105?

RE: Section VIII Div 1 - UG-84 (i)

yes....same heat

RE: Section VIII Div 1 - UG-84 (i)

Or JUST the SA516-70.  
Also, keep in mind, one test plate is req'd for each process used, on cat A & B joints.

RE: Section VIII Div 1 - UG-84 (i)

(OP)
Thank you both for your input.

What about a cat D joint?

RE: Section VIII Div 1 - UG-84 (i)

Don't worry about production testing the Cat D's.  See UG 84 (i)(3)
