Dear sujit

If your code of construction is asme sec8 div1 no need of mockup you can use groove weld qualified wps for tuve to tubesheet

If code of construction is asme sec8 div2 its mandatory to do mockup.

If you have any earlier qualified tube to tubesheet mockup you can use by providing essential variable for tube to rubesheet in sec9
