Thermal Cycling Tester for Plastic Pipes and Fittings
Standards ISO 10508
Application The Hot and cold water cycling tester is mainly used to determine the leakage status of composite pipes & fittings when subjected to specified cycling times under specified internal pressure load.
Product Composition • Sample chamber
• Good quality 304 SUS cold water tank (with chiller & heat exchanger)
• 316 SUS hot water tank with good quality heating elements
Electric control system
Flow measurement (option)
Pre-tension loading system (option)
Features
Full closed loop control: instrument adopts imported full digital control system, the internal pressure of the test pipe system to implement the closed-loop control, automatic control system in the process of operation according to the liquid temperature, operation time, pipe flow adjusting parameters such as the main circulation pump and control valve to make test pipe system internal pressure constant, even in cold, hot water or water hammer in the process of alternating, superior to the national standard requirements.
Intelligent switch: automatic control system according to the sample pipe inlet water temperature, outlet water temperature, cold and hot water tank liquid level, hot and cold switching time, intelligent control open cold water, hot water tank control valve, make the most of the cold water when cold and hot switching back to the cold water tank, cold, hot water tank temperature switch process change less than 5 ºC, system test of low energy consumption.
Multiple safety protection
Liquid level protection: multiple sets of liquid level protection are designed in the cold and hot water tanks. Once the water shortage system automatically stops operation (or water replenishment), the damage of circulating pump due to water shortage is avoided.
Transparent shield: the transparent design of the laboratory can effectively protect the test personnel and facilitate the observation of the test samples.
Unique water flow control: the switching time from cold water cycle to hot water cycle and from hot water cycle to cold water cycle in the test pipeline is less than 1 minute. Within 1 minute, the temperature difference between the sample inlet temperature and the sample outlet temperature is less than 2ºC.
Pre-tensioning device: independent rigid support frame design, using ratchet pre stressing method, can display the loading force process in real time (non-standard, optional device).
