Petrochemical Equipment Safety Evaluation Indentation Tester - Bolt Yield Strength Measurement
Model PMT-1000 measures actual bolt yield strength to avoid seal failure from under-preload. With 1000 N max load, 100 Hz data acquisition, and minor-damage indentation (60-120 μm), it ensures accurate material property assessment. Intrinsically safe for hazardous zones, it is perfect for petrochemical, energy, and pharmaceutical industries.
Key Selling Points
- Accurate Yield Strength Measurement: Directly measures actual bolt yield strength, preventing under-preload and seal failures.
- Intrinsic Safety: Complies with hazardous zone regulations, safe for on-site testing.
- Minor-Damage Indentation: Indentation depth of 60-120 μm minimizes impact on bolt integrity.
- High Data Rate: 100 Hz sampling ensures reliable and fast measurements.
- Portable & Flexible: Supports wired/wireless power, easy to use in the field.
