Many items have a certain degree of elasticity that we cannot see with the naked eye, but this is a phenomenon that does exist. PE pipes also have this situation, and many times we cannot reject it because we cannot see it. So what is the elasticity of PE pipes?
The stiffness of PE tube refers to the ratio of the change in load to the displacement change caused by it. Within the linear characteristic region of the PE tube, the stiffness of the PE tube remains unchanged. In the nonlinear characteristic region of the PE tube, the stiffness of the PE tube varies. In this case, it is meaningful to indicate the stiffness at which the displacement of the PE tube is. When the load applied to the PE tube is a concentrated force, it is called concentrated force stiffness. When the load applied to the PE tube is pressure, it is called pressure stiffness. When the load applied to the PE tube is a moment, it is called moment stiffness or bending stiffness. The reciprocal of the stiffness of a PE tube is called the sensitivity of the PE tube.
When a PE tube is used as a measuring element, the difference between the measured value of its load or displacement and the calculated value obtained based on their linear relationship, and the ratio of the above difference to the maximum load or maximum displacement of the intestine, is called the linearity of the PE tube characteristic. This linear relationship can be a straight line passing through the zero point of coordinates and the endpoint of the measurement range, or a straight line that minimizes linearity.
Therefore, when choosing PE pipes, we need to pay more attention to these aspects, which are very important for us to choose product quality. In addition to strengthening our relevant experience, we also need to learn more about their professional knowledge.
