High-Precision Pressure Threshold Testing for Gas Pipeline Integrity
Client: PT. Citra Tubindo
PT. Citra Tubindo, a leading manufacturer of industrial pipes, required a reliable and accurate method to test the pressure threshold and structural integrity of gas pipes. The goal was to simulate extreme pressure conditions to determine the exact failure point of pipes, ensuring compliance with safety standards and enhancing product reliability. Traditional testing methods lacked the precision needed to capture real-time stress distribution and deformation under high-pressure conditions.
Challenges
- High-Accuracy Stress Measurement: Measuring minute deformations and stress on pipes under extreme pressure with minimal error.
- Precise Failure Point Detection: Identifying the exact pressure level at which the pipe fails using strain gauge technology.
- Multi-Sensor Synchronization: Synchronizing data from four triaxial strain gauges placed at 90° intervals around the pipe to ensure cohesive analysis.
- Real-Time Data Integration: Seamlessly integrating strain gauge sensors with a data acquisition (DAQ) system for real-time monitoring and logging.
