Drick XGNB-N-B Static Internal Pressure Tester for Composite Pipes – Hydrostatic Burst Testing Machine

Overview

The Drick XGNB-N-B Static Internal Pressure Tester is a purpose-built hydrostatic burst testing system engineered for the long-term evaluation of pressure resistance and structural integrity in multilayer composite pipes—including PVC, PE, PP-R, and ABS—under controlled thermal conditions. It operates on the principle of sustained internal hydraulic pressure application while maintaining precise bath temperature stability, enabling compliance with internationally recognized accelerated life testing protocols. The system comprises a high-stability thermostatic medium tank (water bath), a programmable high-pressure generation and regulation unit, a pneumatic safety lid actuation subsystem, and integrated data acquisition architecture. Designed for continuous operation over hundreds of hours, it supports both static endurance testing (per ISO 1167-1 & ASTM D1598) and instantaneous burst evaluation (per ISO 1167-2 & ASTM D1599), delivering reproducible results essential for product qualification, quality assurance, and regulatory submission.

Key Features

• Thermostatic water bath with 15–95 °C operational range, ±0.5 °C control accuracy and uniformity, validated per ASTM E2202 and ISO/IEC 17025 calibration traceability requirements
• High-resolution temperature monitoring at 0.01 °C display resolution, supporting real-time deviation tracking and statistical process control (SPC) reporting
• Pneumatically actuated safety lid with interlocked pressure release logic—meets EN 61000-6-2 electromagnetic compatibility and EN 61000-6-4 emission standards
• Intelligent PID-based controller with built-in memory for ≥400-hour uninterrupted temperature logging; data exportable via CSV or XML format
• Auto-refill system utilizing level-sensing electrodes and solenoid-controlled deionized water injection—designed to maintain constant immersion depth without test interruption or thermal perturbation
• Full-wetted path constructed from ASTM A240 Grade 316L stainless steel, ensuring corrosion resistance against chlorinated or softened water media used in long-duration tests
• Bilingual (Chinese/English) LCD interface compliant with IEC 61000-4-2 ESD immunity and IEC 60529 IP54 enclosure rating

Sample Compatibility & Compliance

The XGNB-N-B accommodates pipe specimens up to Ø315 mm OD and 1,200 mm length, with adaptable clamping fixtures for butt-fused, electrofusion, and mechanical joint configurations. It fully satisfies mandatory test criteria defined in GB/T 6111–2003 (Chinese national standard for plastic piping systems), GB/T 15560–1995 (hydrostatic pressure testing methodology), GB/T 18997.1–2003 and GB/T 18997.2–2003 (aluminum-plastic composite pipe specifications), ISO 1167:2006 (plastics pipes and fittings — determination of resistance to internal pressure), ASTM D1598–2004 (time-to-failure of plastic pipe under constant internal pressure), and ASTM D1599–2008 (short-term hydraulic failure pressure of thermoplastic pipe). All test sequences are configurable to align with GLP-compliant documentation workflows, including electronic signature support and audit-trail-enabled data storage.

Software & Data Management

The embedded controller firmware supports dual-mode operation: standalone mode with local parameter configuration and full-featured PC-connected mode via RS-232/485 serial interface. Optional Drick TestSuite™ software (v3.2+) provides real-time graphical visualization of pressure vs. time and temperature vs. time curves, automated pass/fail classification per ISO 1167 Annex C, and export-ready reports compliant with FDA 21 CFR Part 11 requirements—including user authentication, electronic signatures, and immutable audit logs. Raw datasets include timestamped pressure, temperature, elapsed duration, and system status flags—structured for seamless import into LIMS platforms such as LabWare or Thermo Fisher SampleManager.

Applications

This instrument serves critical roles across R&D laboratories, third-party certification bodies (e.g., CNAS-accredited testing labs), and in-house QA/QC departments of pipe manufacturers. Typical use cases include: validation of multi-layer extrusion bonding integrity under thermal stress; comparative lifetime prediction modeling using the ISO 9080 extrapolation method; verification of raw material batch consistency; assessment of joint reliability in pressurized distribution networks; and technical support for CE marking submissions under EU Construction Products Regulation (CPR) Annex ZA. Its robust architecture ensures stable performance during extended validation campaigns required for WRAS, KIWA, or NSF/ANSI 61 certification pathways.

FAQ

What standards does the XGNB-N-B explicitly support?
It is configured and verified for GB/T 6111–2003, GB/T 15560–1995, GB/T 18997.1–2003, GB/T 18997.2–2003, ISO 1167:2006, ASTM D1598–2004, and ASTM D1599–2008.
Can the system operate unattended for 30 days?
Yes—its controller supports continuous logging for ≥400 hours (16.7 days); with external power backup and networked monitoring, extended campaigns up to 30 days are routinely implemented in accredited labs.
Is the water refill function compatible with deionized water only?
The auto-refill system is optimized for deionized or softened water to prevent scaling; conductivity monitoring prevents activation if TDS exceeds 10 µS/cm.
Does the system include calibration certificates?
Each unit ships with factory calibration certificates for temperature sensor (NIST-traceable Pt100) and pressure transducer (ISO/IEC 17025 accredited), valid for 12 months.
What maintenance intervals are recommended?
Quarterly inspection of O-rings, annual replacement of heat-transfer fluid, and biannual verification of pressure transducer linearity per ISO 6789-2.
