Heat Exchanger Strength Testing at Aces Process

At Aces Process, we prioritize the safety and reliability of our heat exchangers. That's why we subject every unit to rigorous strength testing, including hydrostatic testing, to ensure its structural integrity and leak-tightness before it leaves our facility.

Hydrostatic Testing:

This essential test involves filling the heat exchanger with water and pressurizing it to a specified level, exceeding its normal operating pressure. This simulates extreme operating conditions and helps identify any potential weaknesses or leaks in the welds, joints, or materials.

Benefits of Hydrostatic Testing:

• Verifies Structural Integrity: Ensures the heat exchanger can withstand the intended operating pressures without deformation or failure.

• Detects Leaks: Pinpoints any leaks in the welds, joints, or materials, preventing potential fluid loss or contamination during operation.

• Ensures Safety: Provides assurance that the heat exchanger will operate safely and reliably, minimizing the risk of accidents or equipment failure.

• Meets Industry Standards: Hydrostatic testing is a crucial step in complying with industry standards and regulations, such as ASME Boiler and Pressure Vessel Code.

Our Testing Process:

• Preparation: The heat exchanger is thoroughly cleaned and inspected before testing.

• Filling & Pressurization: The unit is filled with water and gradually pressurized to the specified test pressure,typically 1.5 times the design pressure.

• Holding & Inspection: The pressure is held for a predetermined duration while inspectors visually examine the heat exchanger for any signs of leaks, deformation, or other abnormalities.

• Depressurization & Drainage: The pressure is slowly released, and the water is drained from the heat exchanger.

• Documentation: A detailed test report is generated, documenting the test procedure, results, and any observations.

Your Assurance of Quality:

Hydrostatic testing is a critical step in our commitment to delivering high-quality, reliable heat exchangers. By subjecting each unit to rigorous testing, we ensure it meets the highest standards of safety and performance, providing you with peace of mind and confidence in your investment.
