Best Application: Ring Stiffness Tester for all kinds of plastic pipes.

QT-RST Ring Stiffness Tester is used to determine ring stiffness, ring softness, and compression of thermoplastic pies having a circular cross-section.

Features/Advantages
  • Double-column high rigidity structure, a wide range of speed control
  • Advanced closed-loop AC servo control system enables increase the of controlling accuracy and stability. A high-resolution AD sampling circuit is introduced to collect testing datum, even the peak value will not be lost.
  • Two/Four sensors are connected in a bridge way to strengthen the deflection resist of big pipes, also reduce the mangling rate of load sensor.
  • The unique design of inner diameter measuring system makes specimens easy to install and measurement correct &direct.
  • 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. Creep tests also can be realized (optional).
  • Multi-protection functions from mechanical & electrical design and software, including over-load, over-current and over-temperature.
Theory/Method

ISO 9969-2007 Thermoplastics pipes -- Determination of ring stiffness. It is a standard to test the stiffness, mechanical, deflection and compression properties of plastics, thermoplastic polymers, pipes, plastic pipelines.
