Rapid crack growth testing machine

Standard 

• ISO 13477: Designed exclusively for determining critical pressure (Pc) and temperature (Tc) in polyethylene pressure pipes during rapid crack propagation.

Product Advantages

1. Robust & Adaptable Design

• Universal Compatibility: Tests pipes from Ø50mm to Ø500mm (1629/1671 models) with interchangeable fixtures.
• Motorized Precision: Servo-driven actuator ensures repeatable impact energy delivery.

2. Cutting-Edge Control

• Touchscreen Interface: Pre-programmed ISO 13477 test sequences with adjustable strike velocity (10/15/20 m/s).
• Real-Time Adaptation: Auto-adjusts strike force based on pipe stiffness feedback.

3. Safety & Accuracy

• Pressure Lockout: Prevents test initiation until safe containment is confirmed.
• Laser Alignment: Sub-millimeter positioning of impact head and specimen.

4. Automated Workflow

• Cryogenic Feeder (1671 Model): Robotic arm loads pre-chilled samples (-20°C to -40°C) into test chamber.
• Self-Centering Chucks: Automatic pipe alignment reduces setup time by 60%.

5. Data Integrity

• High-Speed Cameras: 2,000 fps recording of crack initiation and propagation.
• AI-Assisted Analysis: Machine learning algorithms quantify crack velocity (±0.1 m/s accuracy).

Product Features

• Motorized Strike System:
  • Electromagnetic actuator with 0–25 Bar hydraulic boost.
  • 3-stage impact energy calibration (10/15/20 m/s).
• Cryogenic Chamber (1671 Model):
  • Liquid nitrogen cooling with <5°C gradient across 1.2m chamber.
  • Auto-defrost cycle prevents ice buildup.
• Pressure Control:
  • Proportional valve system maintains ±0.1 Bar stability during testing.
  • Explosion-proof pressure vessels rated to 30 Bar.
