Hydrostatic Pressure Tester

The Role of the Hydrostatic Pressure Tester in Quality Assurance

Hydrostatic pressure testers are fundamental instruments used to assess the integrity of pipes, hoses, valves, and other fluid-handling components. By subjecting products to controlled fluid pressure, manufacturers and testing laboratories can identify weak points, leaks, and potential failure modes before products enter service.

Core Features

• High-Precision Pressure Control: Utilizing servo-driven or stepper-motor pumps, the tester maintains target pressures within ±0.1% of setpoint, ensuring reproducible test conditions.

• Automatic Ramp and Hold Cycles: The system can program pressure ramp-up rates, hold times, and pressure drop detection, supporting compliance with standards such as ISO 1167 and EN 1411.

• Leak Detection Sensitivity: Digital flow and pressure sensors detect leakage rates as low as 0.01 mL/min, vital for applications where even minor leaks can pose significant risks.

• Safety Mechanisms: Pressure relief valves, emergency stop functions, and overpressure alarms protect both operators and equipment.

Technical Parameters

• Maximum Test Pressure: 0–30 MPa, selectable

• Pressure Resolution: 0.01 MPa

• Leak Rate Measurement: Range 0–100 mL/min, resolution 0.01 mL/min

• Pressure Medium: Water, oil, or other compatible fluids

• User Interface: Graphical software with multi-language support, test report generation, and remote monitoring capability

Application Scenarios

• Automotive Industry: Testing fuel lines, brake hoses, and cooling-system components under simulated operating conditions.

• Oil and Gas Sector: Validating wellhead equipment, downhole tools, and high-pressure pipelines for deep-well drilling.

• Medical Devices: Ensuring that catheters and fluid delivery systems maintain sterility and pressure integrity.

• Aerospace: Assessing hydraulic and pneumatic lines for aircraft and spacecraft under stringent safety margins.
