Shell and Tube Heat Exchanger - Full Hydrostatic Pressure Testing & Quality Assurance
Yuhong Shell and Tube Heat Exchanger is designed and manufactured in strict accordance with ASME BPVC, TEMA, ABS, GB150 international standards. Our heat exchangers are widely used in petrochemical, oil & gas, power generation, marine, offshore, metallurgy and HVAC systems.
What makes Yuhong different is our strict implementation of full hydrostatic testing for every single unit. Hydrostatic pressure testing is not only a final inspection but a core quality control procedure throughout production. It ensures your heat exchanger can safely withstand design pressure, prevent leakage, resist fatigue, and achieve long service life under harsh working conditions.
Yuhong provides complete testing reports, material certificates, and full quality documentation to meet your project inspection and acceptance requirements.
Why Hydrostatic Testing Is Critical
Hydrostatic testing is the most important safety verification for pressure equipment. It is used to:
- Verify the strength and rigidity of shell, tube bundle, tube sheet and flanges
- Check for leakage at welding joints, tube expansion and sealing surfaces
- Eliminate residual stress caused by manufacturing and welding
- Confirm stability under overpressure conditions
- Ensure compliance with ASME, TEMA, ABS and other third-party standards
Without qualified hydrostatic testing, heat exchangers face risks of cracking, leakage, rupture and safety accidents during operation.
Yuhong Hydrostatic Testing Procedure & Standards
All Yuhong shell and tube heat exchangers undergo complete hydrostatic testing before delivery:
Shell-Side Hydro Test
- Test pressure: 1.5 × Design Pressure
- Holding time: ≥ 30 minutes
- Inspect for deformation, leakage or seepage
Tube-Side Hydro Test
- Test pressure: 1.5 × Design Pressure
- Holding time: ≥ 30 minutes
- Check tightness of tube-to-tube sheet joints (expansion & welding)
Full Assembly Test
- Final integrated pressure test
- Inspect flanges, covers, nozzles and gaskets
- Confirm overall safety and reliability
All tests are performed with clean water, under controlled temperature, and recorded with complete data for inspection.

Key Advantages of Yuhong Hydrostatic Testing
Guaranteed Safety & Reliability
1.5× overpressure testing ensures your heat exchanger is safe under actual working pressure and avoids risks of cracking or leakage.
Full Compliance with International Standards
Testing strictly follows ASME, TEMA, ABS requirements, satisfying third-party inspection, ship classification, and project acceptance.
Leak-Proof Tube-to-Tube Sheet Joints
Hydro testing directly verifies the quality of expansion and welding, ensuring zero leakage during long-term operation.
Elimination of Welding Residual Stress
Pressure holding process helps release stress, improving fatigue life and stability under thermal cycling.
Complete Quality Documentation
We provide pressure test records, inspection reports, material certificates, and data reports to support your acceptance and audit.
Stable Performance in Harsh Environments
Especially suitable for marine, offshore, high-pressure, high-temperature working conditions where safety is critical.
