Tube-to-Tubesheet Welding Types: Choosing the Right Joint …
2020年3月19日 · Design engineers have basically two weld options for a tube-to-tubesheet joint: 1) roll or expand (with grooves milled in tube holes) and seal welded, or, 2) strength welds (no grooves required). Each type of joint has advantages and disadvantages; regardless of which type you choose, it’s crucial to use a welding technique that achieves ...
What are the Tube to Tubesheet Joint Types? - Arc Machines
Tube to tubesheet welding is the primary fabrication process for shell and tube-type exchangers. The multiple tubes require connection to the tubesheet, which can be achieved using a suitable tube to tubesheet joint type. Each joint type has a unique welding demand, which is the key to enhancing overall operational productivity.
