Overview
The Drick XGNB-N-AC Pressure Burst Tester is an engineered solution for long-term hydrostatic pressure resistance and instantaneous burst testing of thermoplastic and composite piping systems. It operates on the principle of controlled internal pressurization under precisely regulated thermal conditions, enabling compliance-driven evaluation of structural integrity, creep behavior, and failure mechanisms in accordance with internationally recognized static pressure endurance standards. Designed for laboratory and quality assurance environments, this system supports accelerated life prediction modeling (e.g., extrapolation to 50-year service life per ISO 9080) by maintaining stable temperature–pressure profiles over extended test durations—up to hundreds of hours—with minimal operator intervention.
Key Features
- Multi-specimen testing chamber: Accommodates up to 6 independent pipe specimens simultaneously, each with isolated pressure control and monitoring channels to eliminate cross-interference.
- High-stability thermal management: Stainless-steel water bath (304 grade) with 80–100 mm thick high-efficiency insulation; integrated anti-thermal-bridge design minimizes heat loss and ensures energy efficiency.
- Precision temperature regulation: PID-controlled heating system with ±0.5 °C accuracy and uniformity across the bath volume; real-time display resolution of 0.01 °C via bilingual LCD interface.
- Intelligent fluid management: Ultrasonic water level sensor coupled with programmable solenoid补水 valve; automatic top-up only initiated during thermal equilibrium, with adjustable flow rate to preserve temperature stability.
- Pneumatic lid actuation: Ergonomic, safety-rated gas-spring mechanism enables smooth, angle-adjustable opening/closing without manual lifting force.
- Dual-interface data acquisition: RS-232/USB port enables continuous logging of temperature and pressure time-series data to external PCs; compatible with custom LabVIEW or MATLAB-based analysis scripts.
- Corrosion-resistant wetted components: All fluid-contact parts—including circulation piping, fittings, heaters, and valves—are constructed from AISI 304 stainless steel to prevent contamination and ensure long-term reliability in aggressive aqueous environments.
Sample Compatibility & Compliance
The XGNB-N-AC is validated for use with rigid and flexible plastic pipes including PVC-U, PE80/PE100, PPR, ABS, and multi-layer composite structures (e.g., PE-AL-PE, PP-R/Al/PP-R). It fully satisfies the mechanical and environmental requirements of ISO 1167-1:2014 (determination of resistance to internal pressure), ISO 1167-2:2014 (test apparatus specifications), GB/T 6111–2018, GB/T 15560–1995, ASTM D1598–2020 (time-to-failure under constant internal pressure), ASTM F1335–2019 (burst testing of polyethylene tubing), ISO 9080:2012 (extrapolation methodology), GB 18252–2000, CJ/T 108–1999, and YD/T 841–2016. Its architecture supports both step-pressure and constant-pressure test modes required for ISO 1167 Annexes A–C and ASTM D1598 Procedure A/B.
Software & Data Management
While the base unit employs embedded intelligent instrumentation for standalone operation, optional PC-based software provides GLP-compliant data handling: timestamped audit trails, user-access controls, electronic signatures (aligned with FDA 21 CFR Part 11 readiness), and automated report generation (PDF/CSV export). Temperature and pressure logs are synchronized at configurable intervals (1 s to 60 min); trend curves support overlay comparison across multiple specimens or test series. Data export protocols include Modbus RTU and ASCII-delimited formats for integration into LIMS or enterprise QA databases.
Applications
- Quality conformance verification for pipe manufacturers prior to certification (e.g., CE marking, WRAS, NSF/ANSI 61).
- R&D validation of new polymer formulations and layered composite architectures under simulated service conditions.
- Third-party testing laboratories performing accredited assessments per ISO/IEC 17025 requirements.
- Regulatory submission support for building code approvals (e.g., IAPMO, ICC-ES) and utility procurement specifications.
- Failure mode analysis—including slow crack growth (SCG), brittle fracture, and interfacial delamination—in multi-material pipe systems.
FAQ
What standards does the XGNB-N-AC explicitly support for long-term hydrostatic strength testing?
It meets all technical provisions of ISO 1167-1/-2, ASTM D1598, GB/T 6111, and ISO 9080 for pressure endurance and lifetime extrapolation.
Can the system operate unattended for 168-hour (7-day) tests?
Yes—integrated temperature logging, auto-refill, leak-tolerant pressure hold, and fail-safe overpressure cutoff enable fully autonomous execution of extended-duration protocols.
Is calibration traceability provided with the instrument?
Factory calibration certificates (NIST-traceable reference standards for temperature and pressure transducers) are included; annual recalibration services are available through Drick’s ISO/IEC 17025-accredited metrology lab.
Does the unit support custom test sequences beyond standard methods?
Via optional PC software, users may define multi-step pressure ramps, dwell periods, and conditional triggers (e.g., “hold at 8.0 MPa until temperature deviation exceeds ±0.3 °C”).
What maintenance intervals are recommended for sustained accuracy?
Quarterly inspection of seals, annual verification of pressure transducer linearity, and biannual cleaning of stainless-steel bath interior using citric acid descaling solution per manufacturer guidelines.
