Overview
The Hengyi HY(BP)-10MPa Computer-Controlled Pipe Burst Testing Machine is a precision-engineered static pressure endurance and burst resistance evaluation system designed for thermoplastic, thermoset, and multilayer composite piping materials used in potable water, gas distribution, geothermal, and industrial fluid conveyance applications. It operates on the principle of sustained hydrostatic pressure application under controlled thermal conditions, enabling both long-term creep rupture life prediction (per ISO 9080 time-temperature superposition methodology) and instantaneous burst strength determination (per ISO 1167–1 hydraulic failure testing). The system employs closed-loop proportional-integral-derivative (PID) pressure regulation with real-time feedback from calibrated digital transducers, ensuring traceable and repeatable test execution across extended durations—up to 416 days per test channel. Its architecture supports concurrent multi-sample evaluation at independently set pressure levels, eliminating cross-channel interference and supporting statistically robust comparative analysis per ISO 1167 Annex B.
Key Features
- Triple independent test channels with fully decoupled pressure control circuits—each channel configurable with unique pressure setpoints, ramp rates, hold durations, and failure criteria.
- Imported high-efficiency, low-pulsation positive-displacement pump integrated with stainless-steel accumulator and dual-stage filtration (5 µm + 1 µm), ensuring stable pressure delivery and extended service life.
- 10.7-inch industrial-grade capacitive touch display with embedded real-time operating system (RTOS), providing full local control, live curve visualization (pressure vs. time), and on-screen data logging without external PC dependency.
- Automatic leak detection algorithm with user-definable thresholds—supports dynamic adjustment of volumetric loss tolerance, pressure decay rate, and stabilization window duration based on pipe geometry and material compliance class.
- Interruption-resilient test recovery mode: automatic resume from last valid timestamp upon power restoration or manual intervention with audit-trail logging compliant with GLP documentation requirements.
- Modular fixture interface compatible with standardized DIN/ISO mounting patterns; supports rapid interchange of clamping assemblies for nominal diameters ranging from Ø90 mm to Ø250 mm (custom fixtures available).
Sample Compatibility & Compliance
The HY(BP)-10MPa accommodates rigid and flexible thermoplastic pipes—including PE, PP-R, PEX, PVC-U, and PB—as well as reinforced composites such as aluminum-plastic multilayer tubes and fiber-reinforced thermosets. All test protocols adhere strictly to internationally recognized standards for hydrostatic pressure testing: ISO 1167–1 (method A for short-term burst, method B for long-term endurance), ISO 9080 (for extrapolated minimum required strength—MRS—and design coefficient derivation), ASTM D1598 (time-to-failure under constant internal pressure), and ASTM F1335 (for crosslinked polyethylene tubing). The system meets mechanical and electrical safety requirements per IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emission), and its software architecture supports optional 21 CFR Part 11-compliant electronic signatures and audit trail generation when paired with validated networked data servers.
Software & Data Management
Test data—including pressure, temperature, elapsed time, and event markers (e.g., leakage onset, burst occurrence)—are recorded at ≥1 Hz sampling frequency and stored in non-volatile memory with timestamping traceable to UTC via NTP synchronization. Export formats include CSV (for statistical analysis in Minitab or JMP), PDF test reports with embedded signature fields, and XML files conforming to ASTM E1461–22 metadata schema. Optional software modules enable automated report generation aligned with ISO/IEC 17025 laboratory accreditation templates, including uncertainty budgeting per GUM (Guide to the Expression of Uncertainty in Measurement) and calibration certificate linkage. All data logs retain immutable revision history, supporting regulatory inspections under FDA, EU Notified Body, or CNAS audit frameworks.
Applications
- Quality assurance of pipe extrusion batches prior to distribution—verifying conformance to PN (pressure nominal) ratings per EN 1555 or ISO 4427.
- Accelerated lifetime modeling of polymer piping systems under elevated temperature (up to 90 °C, with optional heated water bath) using Larson–Miller parameterization.
- Validation of joint integrity for electrofusion and butt-welded assemblies under combined thermal–mechanical stress.
- Third-party certification testing for WRAS, KIWA, NSF/ANSI 61, and DVGW approval submissions.
- R&D evaluation of novel polymer blends or nanocomposite pipe formulations targeting improved slow crack growth (SCG) resistance.
FAQ
What pressure accuracy is guaranteed over the full 0–16 MPa range?
Pressure control maintains ±2% upper deviation and −1% lower deviation relative to setpoint under steady-state conditions, verified per ISO 1167–2 calibration procedures using NIST-traceable deadweight testers.
Can the system operate unattended for multi-week endurance tests?
Yes—the embedded controller supports autonomous execution up to 10,000 hours (≈416 days) per channel with battery-backed real-time clock, watchdog circuitry, and hardware-level fault detection for pump stall, overheating, or pressure sensor drift.
Is remote monitoring supported?
Standard Ethernet (RJ45) and optional RS485 Modbus RTU interfaces enable integration into plant SCADA or LIMS environments; remote access requires customer-provided secure VLAN configuration.
Are calibration certificates included with shipment?
Each unit ships with factory calibration documentation covering pressure transducers (valid for 12 months) and timing module (traceable to national time standard); ISO/IEC 17025-accredited field calibration services are available upon request.
What thermal conditioning options are available beyond ambient testing?
A thermostatically controlled stainless-steel water bath (700 × 600 × 730 mm, 20–90 °C, ±0.5 °C stability) is offered as an optional accessory, fully insulated and equipped with circulation pump, level sensor, and overtemperature cutoff.
