I. Overview
Longitudinal shrinkage is a critical indicator of the quality of plastic pipe products. It reflects the stability of the plastic pipe products in terms of their longitudinal plastic deformation under thermal influence. The measurement of longitudinal shrinkage is significant in enhancing the product's ability to withstand temperature changes, sunlight, and other heat sources during use, as well as in extending the product's lifespan. However, due to the diversity of methods for measuring longitudinal shrinkage, inaccuracies often arise from improper operation or a lack of attention to technique, affecting the accuracy of the test.
