Fixed tubesheet
WebA fixed-tubesheet heat exchanger has straight tubes that are secured at both ends to tubesheets welded to the shell. The main advantage of the fixed tubesheet exchanger … WebJun 17, 2015 · When the tubes are hotter than the shell, then the tubes will be in compression. Over time, tubes in tension or compression may start to loosen from the tubesheet. The strength weld is to reinforce the connection of the tubes to the tubesheet. The reason for specifying strength welding is different from the reason for specifying seal …
