PLEASE LET ME KNOW WHETHER RADIOGRAPHY IS REQUIRED AS PER SECTION VIII DIV.1 BEFORE & AFTER FORMING OF DISHED END WHICH IS FORMED WITH JOINT DUE TO LARGE SIZE?

IS IT OK IF WE RADIOGRAPHED ONLY AFTER FORMING?

I understand that material is clad plate. RT is to be taken only after forming. If you take RT before forming then it may help you to know discontinuities which may be larger in nature (and may be worsened while forming) before forming so that you can repair them. Your cost should have margin to allow Rt before forming.

NO MATERIAL IS NOT CLAD

BOTH DISHED ENDS ARE SEPERATE.

1. FIRST CASE IS 14 THK. SA 516 DISH
IS IT NECESSARY TO HAVE RT AFTER FORMING ALSO
WE PROPOSE TO CARRY RT ONLY BEFORE FORMING.
HEAT TRAETMENT IS NOT REQUIRED BY TAKING INTO CONSIDERATION
PERCENTAGE ELONGATION.

2.SECOND CASE IS 14 THK.SA240 DISH.
HEAT TRATMENT IS REQUIRED AFTER HOT FORMING.
WE PROPOSE TO CARRY RT ONLY BEFORE FORMING.

PL. REPLY CASEWISE.

THANKS A LOT

You are right.
