2. ITP (Inspection and Test Plan) for Carbon Steel Tube Bundles

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:

1. Preparation:

   • Assemble the tube bundle and ensure all openings are sealed with appropriate caps or plugs.

2. Pressurization:

   • Using a calibrated hydraulic pump, gradually increase pressure to the required test level (1.5× design pressure).

3. Hold Period:

   • Inspect all welds, connections, and surfaces for visible leaks or deformation 

4. De-pressurization:

   • Slowly release the pressure after the test duration to avoid damage to the tube bundle.

5. Post-Test Inspection:

   • Record test results and prepare a detailed hydrotest report for client approval
