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.
