	Dear All, Does anyone know what is " full area replacement" meant? What do i understand is that tr in the shell is equal to t of the shell. That's mean there will be no excess thickness in the shell taken into credit. Am i correct? On the other hand,if the shell is flat head type, as per UG-39(b), the area required is equal to 0.5dtr + ttn which is equal to half of area required in the cylindrical shell. If client specification call for "full area replacement", then should i remove the value of *0.5* so that the area required same as cylindrical shell? Thanks in advance.

	Really Peja, your question is not clear for me. You are talking about ASME VIII? UG 39 to UG 40 are quite explicit.

	Dear Whitephone, My question is, do you understand "full area replacement" in term of nozzle reinforcement?

	Cutting the hole for the nozzle in the shell removes a certain amount of cross-sectional area of the shell. Full replacement means that the reinforcing pad adds back as much cross-sectional area as was removed. That may be more than needed, but it simplifies calculation. __________________ In vino veritas; in cervisia carmen; in aqua E. coli.

	Agreed with you. Hence, the excess thickness in the shell will be not taken into account when calculating the nozzle reinforcement.
