Sciteq 2000-2 Static Hydrostatic Pressure Tester

Overview

The Sciteq 2000-2 Static Hydrostatic Pressure Tester is an engineered solution for standardized long-term hydrostatic pressure testing of thermoplastic and composite piping systems, conforming to ISO 1167-1/2, ASTM D1598, EN 921, and GB/T 6111. Built upon Sciteq’s decades of specialization in pipe integrity validation, the system implements a closed-loop, gas-free hydraulic methodology—eliminating compressibility artifacts and ensuring true static pressure fidelity across extended test durations (up to 10,000 hours). Unlike pneumatic or semi-hydraulic alternatives, the 2000-2 utilizes an oil-based, non-volatile fluid medium combined with its proprietary Dynamic Pressure Control System (DPCS), enabling real-time pressure compensation against thermal expansion, viscoelastic relaxation, and minor leakage—critical for compliance with ISO 1167 Annex C requirements for pressure deviation tolerance (±1% of setpoint over time).

Key Features

• Modular 24-inch rack-mount architecture: All functional modules—including pressure source, station controllers, burst valve assemblies, and cyclic actuation units—fit within a standardized 800 mm × 800 mm floor footprint, enabling laboratory space optimization without compromising scalability.
• S40 intelligent controller: Integrated 5.7-inch color touchscreen interface with embedded test sequencing logic; operates autonomously without external PC—supports full test definition, real-time monitoring, pass/fail evaluation per ISO criteria, and on-device data logging (timestamped pressure, temperature, duration).
• DPCS precision regulation: Continuously adjusts hydraulic output via feedback from high-stability piezoresistive transducers (0.1% FS accuracy), maintaining pressure stability within ±0.5% of setpoint under variable thermal load and specimen creep conditions.
• Dedicated burst & cyclic modules: Burst station employs high-flow proportional relief valves with adaptive ramp-rate software (0.1–10 bar/min linear control); cyclic module delivers reproducible 1 Hz sawtooth waveforms using fast-response servo valves and dynamic pressure regulators—fully traceable per ASTM D1599 Annex A.
• Secure remote service infrastructure: TLS-encrypted Ethernet connection enables authenticated remote diagnostics, over-the-air firmware updates, and controlled remote desktop access—designed to meet internal IT security policies while minimizing instrument downtime.

Sample Compatibility & Compliance

The Sciteq 2000-2 accommodates pipe specimens ranging from Ø16 mm to Ø630 mm (DN16–DN630), including PE, PP-R, PVC-U, PEX, multilayer composites, and lined steel conduits. Each pressure station supports independent temperature-controlled water baths (optional integration with external circulators meeting ISO 1167-2 Class I specifications). The system complies with essential regulatory frameworks for quality assurance in pipe certification: ISO/IEC 17025 accredited laboratories routinely validate its measurement uncertainty budget (<0.8% k=2) for pressure and time parameters. Full audit trails—including operator ID, parameter changes, calibration events, and test interruptions—are recorded in immutable binary logs, satisfying GLP documentation requirements and FDA 21 CFR Part 11 electronic record retention standards when paired with validated LIMS integration.

Software & Data Management

The embedded S40 OS provides native CSV export of raw test data (pressure, elapsed time, bath temperature) with ISO 8601 timestamps and configurable metadata fields (sample ID, operator, standard reference, batch number). Optional Sciteq DataLink software (Windows-based) enables centralized fleet management across multiple 2000-2 units, automated report generation per ISO 1167 Annex D templates, and statistical trend analysis (Weibull modulus, failure probability plots). All data files are digitally signed at creation; cryptographic hash verification ensures integrity during archival or third-party review—supporting traceability in dispute resolution or notified body audits.

Applications

• Long-term hydrostatic strength (LTHS) determination for PE100/PE100-RC pipe materials per ISO 9080 extrapolation protocols.
• Burst resistance validation of multilayer pipe systems used in district heating networks (EN 15266).
• Cyclic fatigue assessment of PEX-a tubing under accelerated thermal-mechanical stress (ASTM F876/F877).
• Quality conformance testing for pressure-rated HDPE gas distribution pipes (ISO 4437-2).
• R&D benchmarking of novel polymer formulations under sustained pressure at elevated temperatures (60–80 °C).

FAQ

Does the Sciteq 2000-2 require continuous PC connectivity to run tests?

No—the S40 controller executes all test routines independently; PC connection is optional and only required for advanced reporting or multi-unit synchronization.
Can the system be upgraded from a single-station to a five-station configuration post-purchase?

Yes—modular design allows field installation of additional pressure station modules without hardware replacement or recalibration of existing units.
What pressure media does the system use, and is it compatible with potable water testing requirements?

It uses deionized water or inhibited glycol-water mixtures; all wetted components meet NSF/ANSI 61 and WRAS material compliance when configured per application-specific fluid specifications.
How is calibration traceability maintained across the system’s operational lifetime?

Each pressure transducer carries NIST-traceable calibration certificates; Sciteq provides annual verification kits and documented procedures aligned with ISO/IEC 17025 Clause 6.5.2 for in-house interval checks.
Is the remote support interface compatible with corporate firewalls and proxy servers?

Yes—communication uses configurable TCP ports and supports enterprise-grade authentication (RADIUS/LDAP), certificate pinning, and session timeout policies per ISO 27001 Annex A.8.2.3.
