Abstract: Copper-Nickel alloy heat exchangers were used broadly in methane chloride project in China. Double tubesheet was adopted by some special heat exchangers. The technology of deep-hole strength expansion and inspection were the vital and difficult in fabricating double tubesheet heat exchangers. By application of hydraulic expansion and unique assemble, the difficulties can be resolved.
