Resonant Fatigue Testing

High-speed fatigue testing for energy equipment

We specialize in Resonant/Harmonic Fatigue Testing, applying controlled oscillatory vibrations to evaluate the structural performance of test samples and connections. Our advanced system operates at frequencies up to 30 Hz, cycling continuously until sample failure to determine precise fatigue limits. Test duration varies based on the targeted strain range and material properties. Our high-efficiency system delivers up to 2.5 million cycles per day, providing comprehensive durability analysis in a controlled, safe environment.

Key testing features:

  • Pipe sizes from 3.5" to 14"

  • Fully automated control systems

  • 24/7 operational capability

Get started

  • Our resonant fatigue testing provides complete full-scale high-speed fatigue testing of pipe girth welds and mechanical connectors for energy applications. This advanced testing method dramatically reduces testing time while maintaining accuracy and reliability.

    • The ability to apply fully alternating bending cycles along the full circumference of the pipe

    • Rates up to 2.5 million cycles per day

    • Test frequency of up to 30Hz

    • Pipe size range of 3.5” to 14”

    • 24/7 operational testing

  • We apply fully alternating bending cycles along the full circumference of pipes, testing:

    • Pipe sizes from 3.5" to 14" diameter

    • Girth welds for pipeline systems

    • Mechanical connectors for energy applications

    • Connection performance under cyclic loading

  • Our resonant fatigue systems deliver exceptional testing speeds:

    • Up to 2.5 million cycles per day

    • Test frequencies up to 30Hz

    • 24/7 operational testing capability

    • Years of service life simulated in days or weeks

  • We recently upgraded our resonant fatigue systems with enhanced capabilities:

    • High test frequencies up to 30 Hz

    • 2.5 million cycles in 24 hours

    • Reliable controls with safety shutdowns

    • Continuous automated operation

    These upgrades help manufacturers accelerate time-to-market, get comprehensive fatigue data, and optimize product development.
