Abstract

A support lug casting for supporting a ferritic tube from an adjacent tube comprising male and female lugs formed on a ring shaped member and engaged around but not welded to each tube. The male lug of one tube engages into the female lug of an adjacent tube. The lugs and rings are made of austenitic material which resist corrosion and heat and which avoids the problem of welding dissimilar materials to each other since no welded connection is established between the austenitic casting and the ferritic tube. The casting is axially fixed on the tube by one or more ferritic stops or weld areas which are at one or both axial ends of each casting.
