Drop Hammer Test Equipment for Material Compliance Testing
The Falling Weight Deflectometer Impact Tester for Plastic Pipes is a specialized inspection instrument certified in full accordance with ISO 4422, ISO 3127 and ASTM D2444 testing specifications. This precision equipment is designed for quantifying the external impact resistance of circular cross-section thermoplastic pipes in both laboratory and production line environments.
Testing Methodology
During testing, prepared pipe specimens are subjected to impact loads delivered by a falling striker with pre-defined mass and geometric profile. The striker free-falls from a calibrated height to strike designated positions along the circumference of the test piece, enabling accurate estimation of the authentic impact pass rate for entire production batches or continuous manufacturing runs.
Advanced Product Features
- Anti-rebound mechanism achieving 100% striker capture success rate
- Imported AC servo drive delivering ultra-high positioning precision and rapid crosshead lifting speed
- Flexible impact height operation modes: manual custom setting or fully automatic system calibration
- Comprehensive automatic operator safety protection system with safety-interlocked sample loading door
- Multi-layer shock absorption structure and impact-resistant observation window
- Fully automatic lifting height calibration with deviation strictly controlled within ±2mm
- Modular combined impact hammer structure for flexible weight adjustment
- Pneumatic anti-secondary impact capture mechanism with adjustable working air pressure
- Twin-screw support structure for outstanding operation stability and high structural rigidity
