Pipeline Testing Equipment for Long-Term Pressure and Temperature Cycle Testing
This specialized testing system is engineered for durability assessment of plastic pipeline systems and fittings, assembled according to standard specifications. The system applies preset internal pressure while exposing specimens to cyclic cold and hot temperature conditions over programmed testing periods. Upon completion of test cycles, the system automatically inspects pipes and fittings for leakage or rupture defects.
Testing Protocol Overview
This long-term durability verification requires 5,000 hot and cold water circulation cycles per specimen set, with each cycle lasting 30 minutes (15 minutes cold water followed by 15 minutes hot water). The equipment ensures dependable long-term uninterrupted operation and consistent performance stability. Custom-produced for European markets according to technical standards, this machine has demonstrated zero technical or quality defects during years of operation.
System Configuration
The apparatus comprises four core functional modules: cold water exchange execution module, hot water exchange execution module, specimen test chamber, and industrial water chiller. Features include sleek exterior design, modular structural framework, advanced control technology, steady operation performance, dependable quality, and straightforward user-friendly operation.
Instrument Features
Patent-Protected Open Structure Design: High-temperature, high-pressure water circulates exclusively within test specimens and special connecting pipework. The equipment utilizes atmospheric-pressure vessel design with other circulation pipelines running under standard atmospheric pressure, ensuring long-term dependable operation.
Full Closed-Loop Control System: Employs imported all-digital control system providing closed-loop precise adjustment of internal pressure. Automatically regulates main circulation pump and control valves based on real-time indicators including fluid temperature, operating duration, and pipeline flow velocity.
Smart Cycle Switching System: Control system automatically tunes operation status based on real-time monitoring of inlet/outlet water temperatures, tank liquid levels, and switching intervals. Ensures temperature variation between tanks remains below 3°C for ultra-low energy consumption.
Low-Noise Operation Design: Equipped with exclusive water flow controller that significantly reduces operation noise from high-speed water flow.
High-Performance Refrigeration System: Uses imported industrial chillers with water-to-water cooling technology to enhance refrigeration efficiency and extend service life.
