Pipeline Testing Equipment to Perform Long Term Pressure and Temperature Cycle Testing on Plastic Pipeline Systems and Fittings

Specialized equipment for evaluating the performance of plastic pipeline systems and fittings through rigorous pressure and temperature cycling tests.

This testing procedure represents long-term stability verification, requiring 5,000 hot and cold water circulation cycles per specimen set. Each cycle lasts 30 minutes (15 minutes cold water followed by 15 minutes hot water), demanding reliable long-term operation and consistent performance from the equipment.

Custom-manufactured for European markets in full compliance with European technical specifications, this machine has demonstrated zero technical or quality faults throughout years of practical operation.

The apparatus consists of four core functional components: cold water exchange execution module, hot water exchange execution module, specimen testing chamber, and industrial chiller. It features elegant appearance design, modular architecture, advanced control technology, stable operation performance, reliable quality, and intuitive user-friendly operation.

• Patented Open Structural Design: High-temperature and high-pressure water circulates only within test specimens and dedicated connecting pipelines. The equipment uses atmospheric-pressure container design with all other circulation pipelines operating under normal atmospheric pressure, ensuring long-term reliable operation. This innovative design holds an official technical patent.
• Full Closed-Loop Control Architecture: Utilizes imported fully digital control system for closed-loop precise regulation of internal pressure. The system automatically adjusts main circulation pump and control valves based on real-time parameters including liquid temperature, running duration, and pipeline flow rate to maintain constant internal pressure. Eliminates water hammer risk during rapid hot/cold switching.
• Intelligent Cycle Switching Mechanism: Control system automatically adjusts operation based on real-time monitoring of inlet/outlet water temperatures, tank liquid levels, and switching duration. Intelligently operates return valves to ensure proper water flow management with temperature fluctuation controlled below 3°C, achieving extremely low energy consumption.
• Low-Noise Operation Optimization: Test pipeline includes self-developed proprietary water flow controller that significantly reduces operation noise from high-speed water flow erosion.
• High-Efficiency Refrigeration System: Uses imported industrial chillers with water-to-water cooling technology to boost refrigeration efficiency and ensure optimal compressor operation, improving cooling efficiency and extending chiller service life.
