| 2 | Tube Dimensional Check | Per design drawings and tolerances | QC |
| 3 | Tube Sheet Inspection | As per ASME Sec VIII requirements | QC |
| 4 | Tube-to-Tube Sheet Welding | ASME Sec IX standards | Third-Party Inspector |
| 5 | Baffle and Support Assembly | TEMA Class R specifications | QC |
| 6 | Hydrostatic Testing | No leakage or pressure drop | Authorized Inspector, Client |
| 7 | Final Inspection | TEMA standards | Client, Third-Party Inspector |
| 8 | Documentation Approval | Complete and accurate documentation | Client, QC |
3. Hydrostatic Testing Requirements and Procedure
Key Requirements:
- Test Standard: ASME Section VIII Division 1.
- Pressure: 1.5× design working pressure.
- Hold Time: 2 hours usually we do.
Testing Procedure:
-
Preparation:
- Assemble the tube bundle and ensure all openings are sealed with appropriate caps or plugs.
-
Pressurization:
- Using a calibrated hydraulic pump, gradually increase pressure to the required test level (1.5× design pressure).
-
Hold Period:
- Inspect all welds, connections, and surfaces for visible leaks or deformation
-
De-pressurization:
- Slowly release the pressure after the test duration to avoid damage to the tube bundle.
-
Post-Test Inspection:
- Record test results and prepare a detailed hydrotest report for client approval
