Pipe Testing Equipment for Standard Pressure‑Temperature Cycle Test of Plastic Pipes and Fittings
Summary:
1. Classified as a long‑term service‑life validation test, this protocol mandates that a complete set of plastic pipeline system specimens undergo 5,000 cycles of hot‑cold water alternating circulation. Each full cycle takes 30 minutes in total, comprising 15‑minute cold‑water circulation phase and subsequent 15‑minute hot‑water circulation phase. Such test conditions impose high requirements on test hardware for sustained uninterrupted running capacity as well as steady, repeatable performance output. Purpose‑built by our factory for a well‑known European brand, this test unit is fully engineered in accordance with European technical specifications. Multiple‑year field deployments within European markets have proven its fault‑free running record without technical breakdowns or quality‑related defects.
2. The system comprises four key functional assemblies: cold‑water exchange actuation module, hot‑water exchange actuation module, specimen test enclosure and industrial cooling chiller. It delivers refined exterior styling together with modular mechanical layout, state‑of‑the‑art control algorithms, stable runtime behaviour, robust build quality and straightforward, user‑oriented operation interface.
Instrument Features:
Full Closed‑Loop Control Architecture
Featuring an imported all‑digital control platform, this test unit realizes closed‑loop high‑accuracy internal pressure modulation for the complete piping test circuit. In the course of testing, the main circulating pump and regulating valves get dynamically tuned by the control platform according to real‑time feedback of fluid temperature, elapsed runtime and pipeline flow velocity, so as to sustain uniform system‑wide internal pressure. This structural configuration effectively avoids water‑hammer hazards even under fast hot‑cold fluid mode alternation, whose comprehensive performance outperforms the criteria laid down by relevant national standards.
Intelligent Cycle‑Transition Mechanism
Leveraging real‑time monitoring signals covering inlet & outlet water temperature of sample pipelines, liquid levels of cold‑hot water reservoirs and mode‑switch timing parameters, the control platform autonomously modifies system working states. It intelligently governs the return‑path valves for both reservoirs, diverting most cold‑phase fluid back into the cold‑water tank upon cycle transition. Temperature deviation between the two tanks is rigorously confined within 3 °C, bringing about remarkably low energy expenditure during prolonged continuous system runs.
Low‑Noise Performance Enhancement
A self‑developed in‑house water‑flow regulating component is integrated onto the test piping loop, which greatly suppresses acoustic noise triggered by high‑velocity fluid scouring effects.
High‑efficiency Refrigeration Configuration
Imported industrial chillers serve as the low‑temperature cold source for this system. Water‑to‑water cooling technique is implemented to elevate refrigeration efficiency and keep compressors functioning within their optimal operating envelope. Such arrangement brings higher overall cooling capacity and notably prolongs the service lifespan of the industrial chiller hardware.
