Which is the best projection for a shell heat exchanger?
The most common tube projection for shell and tube heat exchangers is 1/8 from the tube sheet. In situations where all tubes will be rolled to the same projection, an expander with a recess collar should be used. This will accommodate the projection and prevent the tube from being pulled into the expander.See all results for this questionWelding Techniques For Thin-Walled Stainless Steel Tubes smooth tube sheets for heat exchanger Plasma weldingOct 18, 2019 · Welding Techniques For Thin-walled Stainless Steel Tubes The thin-walled stainless steel tubing generally means: the pipe diameter is 5 to 50 mm, and the wall thickness is 0.3 to 1.0 mm.

In this scenario, an expander with double radius rolls should be used. Double radius refers to the smooth taper that is present on both ends of the roll. This allows for a smooth transition and prevents any ridges or lips from being left inside of the tube after expansion.Main points of welding technology of heat exchanger tube The tube sheet and tube holes can be cleaned with acetone or carbon tetrachloride. The tack welding should be spot welded at 3 o'clock and 9 o'clock. The welding specification must be the same as the formal welding. Do not spot weld, and ensure the penetration. When welding the first pipe head, it is necessary to start the arc outside the groove.
