Jiubin JB-150-BK Microcomputer-Controlled Static Hydraulic Burst Testing Machine for Pipes

Overview

The Jiubin JB-150-BK Microcomputer-Controlled Static Hydraulic Burst Testing Machine is an engineered solution for evaluating the long-term hydrostatic pressure resistance and instantaneous burst strength of thermoplastic and composite piping systems. Designed in strict accordance with ISO/IEC 17025-aligned test methodologies and harmonized with ASTM D1598, ISO 1167-1/-2, and GB/T 6111–2003 and GB/T 15560–1995, this system applies controlled, sustained internal hydraulic pressure to pipe specimens under regulated thermal conditions. It operates on the principle of static pressurization—where pressure is maintained at a defined setpoint for extended durations (up to 10,000 hours) while monitoring time-to-failure or deformation behavior—enabling accelerated life prediction via stress-rupture modeling (e.g., ISO 9080 extrapolation). Its architecture integrates closed-loop servo-hydraulic control, high-fidelity pressure transduction, and precision thermal management to support regulatory compliance testing for pipe certification, quality assurance, and material development.

Key Features

• Triple independent test channels—each with dedicated high-pressure solenoid valves (GSR Germany), triplex plunger pump (U.S.-sourced), and circulation pump (WILO Germany)—enabling concurrent, non-interfering tests on up to three specimens.
• Real-time pressure regulation with ≤±1% full-scale accuracy and dynamic control band of –1% to +2%, achieved via adaptive intermittent replenishment using hydraulic accumulators—minimizing pump duty cycle and enhancing system longevity.
• Ultra-fast pressure acquisition at 50 Hz (20 ms sampling interval), eliminating display lag and ensuring fidelity in rupture event capture and pressure transient analysis.
• Integrated temperature-controlled bath with 20–95 °C range, ±1 °C stability and uniformity, stainless-steel insulated tank, and external recirculation loop for homogeneous thermal distribution across specimen length.
• Fail-safe rupture detection: automatic isolation of failed channel via valve shutoff, continuous operation of remaining channels, and timestamped digital logging of failure mode (leak vs. burst).
• Robust data integrity architecture: local storage of raw pressure/time/temperature streams, audit-trail-enabled test session metadata, and export-ready datasets compatible with LIMS integration.
• Intuitive Windows-based control software supporting programmable multi-step pressure profiles, real-time curve overlay (pressure vs. time per channel), automated report generation (PDF/Excel), and GLP-compliant electronic signatures.
• Modular mechanical design featuring O-ring sealed A-type end caps for rapid specimen loading/unloading across wide diameter range (φ12–φ630 mm), with optional custom fixtures for non-standard geometries.

Sample Compatibility & Compliance

The JB-150-BK accommodates rigid and semi-crystalline thermoplastic pipes—including PVC-U, PP-R, PE-Xa/b/c, PE-RT, PB, and multilayer composites (e.g., aluminum-plastic, steel-plastic)—as well as crosslinked polymer systems used in potable water, district heating, and industrial fluid conveyance. All test configurations conform to mandatory requirements for CE-marked pipe products sold in EEA markets and meet the technical validation criteria of NSF/ANSI 61, EN 1452-2, EN 1555-2, and AS/NZS 4129. The system supports full traceability per ISO/IEC 17025:2017 Clause 7.8 (reporting) and enables Part 11–compliant data handling when configured with user authentication, change logging, and electronic record retention protocols.

Software & Data Management

The proprietary JB-TestSuite v4.2 software provides deterministic real-time control with sub-second command latency and synchronized multi-channel I/O. It records pressure (MPa), elapsed time (h:min:s), bath temperature (°C), and event flags (leak onset, burst, valve actuation) at configurable intervals. Raw binary logs are stored in HDF5 format for archival integrity and post-processing interoperability with MATLAB, Python (pandas/h5py), or Minitab. Reporting modules generate ASTM-compliant test certificates—including specimen ID, material grade, test standard reference, pressure history plot, failure time, and operator verification—fully editable prior to digital signing. Audit trails log all user actions (login/logout, parameter edits, test start/stop), meeting FDA 21 CFR Part 11 and EU Annex 11 expectations for regulated environments.

Applications

• Certification testing per ISO 1167-2 for pipe classification (e.g., PN rating derivation).
• Long-term hydrostatic strength (LTHS) determination for ISO 9080 lifetime extrapolation.
• Quality conformance verification in pipe manufacturing QC labs (incoming/outgoing inspection).
• R&D evaluation of novel polymer formulations, nanocomposite reinforcements, or fusion joint integrity.
• Third-party accreditation testing for CNAS, CMA, or TÜV-certified laboratories.
• Validation of thermal aging effects on pressure resistance under elevated temperature soak conditions.

FAQ

What standards does the JB-150-BK comply with for international pipe certification?
It fully implements ISO 1167-1/-2, ASTM D1598, GB/T 6111–2003, and GB/T 15560–1995, with hardware and software architecture validated for EN 1452-2 and NSF/ANSI 61 alignment.
Can the system perform both constant-pressure hold and step-pressure ramp tests?
Yes—the software supports programmable multi-segment profiles, including linear ramps, dwell periods, and pressure staircases, with independent scheduling per channel.
Is remote monitoring or networked data export supported?
Standard Ethernet TCP/IP interface enables SCADA integration; optional OPC UA server module allows real-time data streaming to MES or cloud-based analytics platforms.
How is calibration traceability maintained?
Each unit ships with NIST-traceable pressure and temperature calibration certificates; onboard self-diagnostics verify sensor linearity and valve response prior to each test sequence.
What maintenance intervals are recommended for long-term reliability?
Plunger pump oil change every 2,000 operating hours; accumulator precharge verification annually; full system performance validation per ISO 21506 biannually.
