Fatigue Testing

Advanced fatigue testing for long-term durability

We provide advanced Fatigue Testing services for critical oil and gas components to evaluate their durability under cyclic loading conditions. Our testing capabilities simulate real-world operational stresses — such as pressure and load, mechanical vibrations, and thermal cycling — to assess component performance over time. Our data-driven approach helps mitigate failure risks, extend service life, and enhance operational safety.

Get started

  • Our resonant fatigue applies oscillatory vibrations to test structural capabilities:

    • Test frequencies up to 30 Hz

    • Up to 2.5 million cycles per day

    • Pipe sizes from 3-½" to 14" diameter

    • Fully automated control systems

    • 24/7 operational capability

    We apply fully alternating bending cycles around the full circumference, simulating realistic operational fatigue loading for girth welds and mechanical connectors.

  • Our rotary fatigue simulates combined rotational and bending stresses:

    • Sample rotation up to 30 RPM

    • Maximum outer diameter: 6 inches

    • Up to 40,000 cycles per day

    • Wireless strain gage capabilities

    • Combined pressure and rotation testing

    This testing determines how components handle rotational and bending forces simultaneously, often while under pressure.

  • For components experiencing high stresses with plastic deformation:

    • Controlled application of cyclic loads

    • Combined axial and bending fatigue

    • Integration with pressure cycling

    • Temperature-controlled fatigue testing

    • Comprehensive strain measurement

  • Real-world fatigue rarely occurs under simple conditions. We can combine:

    • Multiple cyclic load types simultaneously

    • Pressure and load cycling together

    • Thermal cycling during fatigue testing

    • Complex load sequences and spectra

    • Realistic field condition simulation

    • Oil and Gas: Premium connections, drill pipe, riser connections

    • LNG: Connections for liquid natural gas applications

    • Geothermal: Equipment for geothermal energy systems

    • Carbon Capture: Components for carbon capture applications

    • Industrial: Manufacturing equipment durability

    • Aerospace: Critical component testing

    • Robotics: System component testing

    • Patented control software for precise operation

    • High-speed data acquisition systems

    • Real-time monitoring and safety controls

    • Automated test sequences

    • Remote monitoring capabilities

  • Many equipment failures result from repeated stress cycles over time, not single overloads. Fatigue testing:

    • Predicts long-term durability

    • Identifies potential failure mechanisms

    • Validates design life expectations

    • Supports preventive maintenance planning

    • Ensures reliable field performance
