Product Introduction

1.  Product Overview

The NJTT-980 silicon core tube cold bending radius tester is developed by Beijing Naijiu Weiye Technology Co., Ltd. for measuring the bending resistance of silicon core tubes at low temperatures in accordance with standard JT/T 496-2018. This equipment is simple and intuitive, and is the preferred equipment for production and quality supervision and inspection departments.

2. Main technical parameters

It can meet the requirements of high-density polyethylene silicon core plastic pipes for underground communication pipelines with different diameters ranging from 32-63mm.

Other testing equipment: a low-temperature box with a temperature controlled at -20 ℃ ± 2 ℃.

Sample: Take three 1.5 meter (2 meters when the outer diameter is greater than 40mm) long silicon core tubes as samples for the bending performance test. Before the test, the samples should be placed at a temperature of -20 ℃ ± 2 ℃ for 2 hours
