Stiffness tester JJ-RST

ring crush (RCT)for pipethermoplastic pipe

Ring stiffness tester Overview This tester is used to determine the ring stiffness, compression, ring softness of thermoplastic pipes having circular cross-section. It conforms to the requirement of all kinds of plastic pipes, structured-wall pipes, PE corrugated pipes, helically wound pipes etc. Standards ISO 9967, ISO 9969, ASTMD 2412 and the equivalent. Characters 1.Double-column high rigidity structure，wide range of speed control 2.Advanced closed-loop AC servo control system enables to increase the controlling accuracy and stability. High resolution AD sampling circuit is introduced to collect testing datum, even the peak value will not be lost. 3.Two/Four sensors are connected in a bridge way to strengthen the deflection resist of big pipes, also reduce mangling rate of load sensor. 4.Unique design of inner diameter measuring system makes specimen easy to install and measurement correct &direct. 5.Connect the tester to PC via RS232 to control test and download the test data, PC software may realize the functions of test data storage, statistics, analysis and test results printout. 6.Multi protection functions from mechanical & electrical design and software, including over-load, over-current and over-temperature.
