I had specified for an exchnager (AEL type) Admiralty tubes, (for cooling water) Naval brass for tube sheet, and CS for Shell (Naphtha) will there be any problem with the tube sheet to shell joint (welding), or for tubesheet to tube joint expecting your reply regards, N.S.Babu

Thank you for your reply, Nnyway i had also raised the same query to some of the experienced personnel inthe refinery field, they also told the same, welding is not a problem, but if we specify AEL type the tube sheet can be specified as brass clad or overlay, for simple and good welding or we can specify AES type so that we can avoid the weld itself. However we have to look into the cost of the claded material and the AES floating head. the cheaper one can be used. N S Babu.
