Overview
The Hengyi HY(BP)-16MPA Pipe Hydrostatic Burst Testing Machine is a precision-engineered static pressure endurance and burst evaluation system designed for polymeric and composite piping materials used in potable water, gas distribution, geothermal, and industrial fluid conveyance applications. It operates on the principle of controlled hydrostatic pressurization—applying and maintaining calibrated internal water pressure within sealed pipe specimens under constant temperature conditions—to quantify long-term hydrostatic strength (LTHS), time-to-failure at specified stress levels, and instantaneous burst resistance. The system complies with internationally recognized accelerated life testing methodologies defined in ISO 1167 (Parts 1–4), ISO 9080 (for extrapolation of creep rupture data), and ASTM D1598 (time-to-failure under constant internal pressure). Its architecture supports both step-pressure and ramp-hold test profiles, enabling compliance with regulatory validation protocols required for pipe certification under EN 1555, AS/NZS 4129, and CSA B137 series standards.
Key Features
- Triple independent test channels—each with isolated pressure control, real-time monitoring, and autonomous failure detection—eliminating cross-channel interference during multi-specimen evaluation.
- High-fidelity pressure regulation using a U.S.-sourced GIANT GXR25 high-pressure plunger pump, coupled with a precision GEMS 20 MPa transducer (UK) and GSR solenoid valves (Germany) for stable pressure hold within ±2% upper / −1% lower tolerance over extended durations.
- Embedded Delta PLC controller (Taiwan) integrated with a 10.7-inch industrial-grade resistive touchscreen HMI (Delta, Taiwan), supporting full Chinese/English bilingual interface, programmable test sequences, and on-device data logging without external PC dependency.
- Automated leakage threshold configuration—users define dynamic pressure drop criteria (e.g., >0.1 MPa/min decline over 60 s) to distinguish between permeation, micro-leakage, and catastrophic rupture events.
- Intelligent test recovery protocol: following power interruption or manual pause, the system preserves all prior pressure-time history and allows resumption either manually (user-confirmed restart point) or automatically (resume from last stable pressure plateau).
- Rugged stainless-steel custom-manufactured fittings and pressure vessel components ensure long-term corrosion resistance and mechanical integrity under cyclic thermal and hydraulic loading.
Sample Compatibility & Compliance
The HY(BP)-16MPA accommodates rigid and flexible thermoplastic pipes (e.g., PE, PP-R, PVC-U, PB, PEX) and multilayer composites (e.g., PE-AL-PE, PERT-Al-PERT) with outer diameters ranging from 20 mm to 315 mm. Optional custom fixtures—including 90 mm, 110 mm, and 250 mm stainless-steel end caps—are available to meet dimensional requirements per ISO 1167 Annex B and ASTM D1598 Section 7. For elevated-temperature evaluation, an optional insulated stainless-steel water bath (700 × 600 × 730 mm internal volume, 20–90 °C range, ±0.5 °C stability) enables testing per ISO 9080 Annex C and GB/T 6111–2003 Clause 6. All hardware and software functions are traceable and audit-ready for GLP and GMP environments; electronic records include timestamped pressure/time arrays, event logs (valve actuation, leakage triggers, interruptions), and digital signatures compliant with FDA 21 CFR Part 11 requirements when paired with validated Delta HMI firmware.
Software & Data Management
Data acquisition occurs at 10 Hz per channel, storing raw pressure, elapsed time, and system status flags in non-volatile memory. The embedded Delta ISaGRAF runtime environment supports user-defined test templates, automatic curve generation (pressure vs. time, log(time) vs. stress), and export of CSV-formatted datasets compatible with ASTM E29, ISO 5725, and ISO/IEC 17025 uncertainty analysis workflows. Reports include pass/fail annotations against reference standards, statistical summaries (mean time-to-failure, Weibull shape/scale parameters), and graphical overlays for inter-batch comparison. Audit trails record operator ID, parameter changes, calibration events, and firmware updates—retained for ≥10 years per ICH E6(R3) data retention guidance.
Applications
- Quality assurance of PE100/PE100-RC pipe systems for municipal water infrastructure.
- Validation of pressure class ratings (PN10, PN16, PN20) per ISO 4427 and EN 12201.
- Accelerated lifetime prediction using regression-based extrapolation from 10,000-hour test data per ISO 9080 procedures.
- Material development support for novel polymer blends and nanocomposite pipe matrices.
- Third-party certification testing for CE marking, WRAS approval, and NSF/ANSI 61 compliance.
- Root cause analysis of field failures via comparative burst morphology assessment across production lots.
FAQ
What pressure accuracy is maintained during extended 10,000-hour tests?
The system sustains pressure control within +2% / −1% of setpoint across the full 0–16 MPa range, verified per ISO 1167-3 Annex A using NIST-traceable deadweight testers.
Can the machine perform simultaneous tests at different pressure levels on each channel?
Yes—each of the three channels operates independently with separate PID loops, allowing concurrent execution of distinct test profiles (e.g., 8 MPa on Channel 1, 12 MPa on Channel 2, ramp-to-burst on Channel 3).
Is temperature control integrated, or is it optional?
Base configuration operates at ambient temperature; the heated water bath (20–90 °C, ±0.5 °C) is an optional add-on configured to meet ISO 9080 thermal conditioning requirements.
How is data integrity ensured for regulatory submissions?
All measurements are time-stamped with UTC-synchronized clocks, stored with cryptographic hash verification, and exportable in ALCOA+ compliant formats including PDF/A-2 and signed CSV with embedded metadata for FDA 21 CFR Part 11 and EU Annex 11 adherence.
Are calibration certificates provided with the system?
Yes—factory calibration includes accredited pressure transducer verification (UKAS-certified lab), timing circuit validation, and full system functional test report traceable to SI units.
