Overview
ZTT-980 silicon core tube cold bending radius tester is developed by Beijing Tiandi Spark Technology Development Co., Ltd. in accordance with the People's Republic of China transportation industry standard JT/T496-2004 "Highway Underground Communication Pipeline High Density Polyethylene (PE) Silicon Core Plastic Pipe" in the silicon core tube cold bending radius test method. The equipment is simple and intuitive, and is a satisfactory equipment for production and mass supervision and inspection departments.
Features
1. Suitable for measuring the anti-bending performance of silicon core tubes at low temperatures
2, can meet the diameter of 32-63mm different diameter underground communication pipe high density polyethylene (PE) silicon core plastic pipe
3. The equipment is simple and intuitive, easy to operate
Principle
According to the test method of silicon core tube cold bending radius in JT/T496-2004 standard, the tester conducts a bending test by holding the silicon core tube sample in a low-temperature chamber at -20 ° C +/- 2 ° C for 2 hours in advance, and detects its anti-bending performance.
Applications
Production and mass supervision and inspection department
Steps
Take three 1.5-meter (2-meter when the outer diameter is greater than 40mm) long silicon core tubes as samples
2. Place the sample at -20 ° C +/- 2 ° C for 2 hours
3. Conduct bending test
4, check whether the sample cracking, crazing or obvious stress blushing phenomenon
Notice
• The specimen must be placed at -20 ° C +/- 2 ° C for 2h before the test
• The specimen should not appear cracking, crazing or obvious stress blushing after bending test
• Need to be equipped with a low-temperature chamber that can control the temperature at -20 ° C +/- 2 ° C
