With the rapid development of the construction industry, the demand for plastic pipes is increasing, and the quality requirements for pipes are also increasing. In order to ensure the quality of the pipe, its performance needs to be comprehensively detected during production. The longitudinal plastic change as an important indicator to measure the performance of the pipe is related to the reliability and durability of the pipe in actual use. Therefore, it is particularly important to detect it scientifically and accurately.
[0003] In the existing pipe plastic change detection process, a marking device is usually used to mark on the surface of the plastic pipe to define the area to be measured. Specifically, the pipe is placed on a platform, and a hand marking device is used to draw two closed circumferential lines on the surface of the pipe sample, and then it is placed in an oven for heating. After heating is completed, the distance difference between the two marks is measured to determine the longitudinal change of the pipe under the heating condition. However, in the actual marking operation process, the operator needs to manually rotate the pipe. Due to the uneven cutting of the end of the pipe, and the uneven force during operation, it is easy to cause the pipe to slip during marking, which not only increases the difficulty of marking, but also affects the accuracy of the final test results.
