# 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.

## Scope

- Tubesheets for shell-and-tube heat exchangers
- Oil cooler and evaporator tubesheets
- Tube installation, expansion and welding on new units

## Work steps

1. Confirm drawings and materials
2. Drill the tube holes
3. Dimensional inspection
4. Install, expand and weld the tubes
5. Testing and documentation handover

## Duration

Depends on tubesheet size, hole count and material; the contract sets the final dates.

## Quality control

- Tube hole dimensional checks
- Leak testing after expansion
- Pressure test
