Heat Exchanger Tubesheet Manufacturing
Tubesheet manufacturing for shell-and-tube heat exchangers, oil coolers and evaporators, plus installation of new units (tube installation, expansion and welding).
In tubesheet manufacturing, drilling the tube holes is the critical operation: hole accuracy and consistency directly affect the quality of the expanded joints later on.
Installing a new heat exchanger covers tube installation, expansion and welding of the bundle.
