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 fromØ50mm 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.
Safety Systems:
Dual-layer acrylic shielding with interlock sensors.
Emergency venting system activates within 50ms.
Software Suite:
CrackVision 3D™: Synchronizes pressure, temperature, and high-speed video data.
Cloud RCP™: Remote monitoring for global teams with API integration.
