Heat exchangers or gas condensers form a critical part of the applications that use process fluid for heating or cooling applications. Especially, the shell and tube type is used commonly across petrochemical refineries, the food and beverage industry, power plants, and other major industries for extensive heating, cooling, or refrigeration. Fabricating these exchangers, however, is a unique challenge in itself.
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.
