[MW:30055] Re: Requirement of double Normalizing of SA-516 Gr.70

this is all because of asme sec 8 div1 ucs 85 , ug 85

1.if you didint purchase  2 normalise plate + pwht than when you doing simulation test its get chances of fail so its  for safe side purchase plate from mill  already fulfill this condition its give confidence for simulation .if you have same kind of palte at your fabrication workshop try this with non 2 normalised + non pwht plate you will get result alter to your requirements

same concern for wps  .

In our recent project i encounter one problem.

Material Grade : SA-516 Gr.70 Supply condition : Normalized

Dished end : Ellipsodial

Thickness : 45 mm

Forming process : Cold forming

Dished end have one cordal seam

Impact required at : -46 deg. C

so during cold forming vendor need one intermediate normalizing. and as per client requirement one more normalizing performed after complete dished end forming. So, total 2 time normalizing have to perform.

So, my question is ; 

(1) During plate order i have to take 2 normalizing cycle simulation ? Yes Or No? With Reason

(2) May I take benefit of Clause UCS-85 (i) of ASME sec-8 Div.1?

(3) Is same clause applicable for welding?

(4) And If i will perform double normalizing then I have to simply double the normalizing time or 2 separate normalizing i have to perform?

(5) What will be effect on weld and base material after 2 time Normalizing?

(6) if any one encountered such issues . please help to solve
